1) Evolutionary theory can allow for deleterious traits to arise. Usually they "ride along" next to some other trait that is overwhelmingly beneficial. Impulses of moral altruism might be connected to structures of social learning that have lead to marvels throughout our lives: from our use of fire to our understanding of modern engineering.
2) Evolutionary theory need not explain any specific learned beliefs, especially once it demonstrates how our processes for learning an incredible variety of beliefs are advantageous on the whole. I can train a pigeon to fly into walls. Since learning for the pigeon is bad for it in the specific, it doesn't mean that learning for the pigeon is bad in the general... my trained pigeon is not a counterexample to evolution. The critic of the theory must first demonstrate that altruism is not simply a learned belief, but in fact, a genetic trait. I suspect this will be difficult, likely impossible. But even if it should be found to be provably true, it will probably contribute more to evolutionary theory than detract from it, as it reaffirms how phenotype is linked to genotype.

# There are similarities that cannot rationally be attributed to design. For example, an endogenous retroviral element (ERV) is a retrovirus (a parasite) that has become part of the genome. There are several kinds of ERVs, and they can insert themselves at random locations. Humans and chimps have thousands of such ERVs in common -- the same type of ERV at the same location in the genome (D. M. Taylor 2003).
Your right, the Human Genome is acquiring an ever greater number of genetic disease. Humans are not improving from a baseline. I challenge you to give an example of how we are becoming more fit. The people I see suffering in hospital beds from crippling bone pain are far from agreeing with you that their sickle cell mutation is beneficial. Similar for the many other hematologic diseases which many evolutionists tout as evidence.
Perhaps you may refer to a mutation of CCR5 providing resistance against some strains of HIV. 1. HIV is not & likely will not be expressed throughout the entire human population
2. This confers no benefit, except on exposure to HIV. Condoms can be beneficial too. Viruses mutate much faster than our genome dose & if they are exposed to multiple STD's concurrently then that worsens the prognosis.
I will say more, after I can respond to your critique about me not considering how HIV affects the population long term. The evolutionary "shades of grey" or slowly changing over time are not realistic. The earth is very limited in its capacity.
Response
I don't understand why you don't consider a mutation beneficial when it could potentially benefit "only" about 40 million people, plus an estimated 14,000 additional people each day [1]. Furthermore, there is evidence that the CCR5-delta-32 mutation which protects against AIDS also protects against another disease, perhaps smallpox or plague [2]. Another mutation, giving rise to apolipoprotein A-1(Milano), prevents atherosclerosis, protecting against heart disease [3].
You seem to have missed the point that many ERVs appear to be common to humans and chimp, and in a pattern that indicates common descent, not design. Good thing, too, in my opinion, because design would indicate that suffering such as you refer to was done on purpose.

Among the great diversity and similarity of the universe, philosophers, scientists, theologians seek to relate one phenomenon to another and to recognize the causes and effects of phenomena. In this way, they have developed explanations for the changing of the seasons, the movements of the sun and stars, the structure of matter, the history of life on Earth, the changes in the society, and many other occurrences. Alternative models, processes, formulas, and theories in many areas are developing to help our understanding of how the universe works. The theory of evolution is one of the most important ideas ever generated by the application of scientific methods to the universe. Evolution in the broadest sense explains that what we see today is different from what existed in the past. The term “evolution” not only concerns changes in living things during the history of life on Earth but also refers to the changes of the universe over time, including cultural changes.
Evolutionary theory incorporates a large body of scientific facts, laws, tested hypotheses, and logical inferences but it is much harder to support scientifically in one process, one model, one formula, or one theory. This is because of the great diversity and similarity among the universe, the explanation of only evolutionary theory can not be applied to everything. For instance, biological evolution provides an explanatory framework for the processes of natural change, but that it can not be applies uncritically to cultural phenomena, the evolutionary formulas for making a universe and making life can enable everything- with the exceptions of man-made things, such as computer or buildings, and of complicated things, such as wooden boxes with nails in them, require thought, intelligence, and careful workmanship.

That nearly every early civilization has an account of a global flood hardly vindicates the biblical flood story. First the flood stories of other early civilizations have them occuring at different times. Some earlier (the Indian, Shatapatha-Brahmama epic dates to 2000 BCE). Some later (the Mayan Popol-Vuh epic which dates to the classic period 200-1000CE). (Interestingly, one of the oldest civilizations, the Egyptian, does not have a flood epic to brag about.) The real problem with the global flood, (aside from the lack of evidence) is the "global" area of most ancient cultures was a area of about 250-500 miles in diameter. That was their universe. Factor in the evidence that most early cultures lived on or near rivers and seas, and a major flood did occur, such as the floods created by Lake Missoula in Eastern Washington State, it certainly would have been preceived as a "global" event to them.
Many of us that study philosophy do question the writings of Plato, Aristotle, Homer et al. just as we do the Bible. The discipline of Higher Criticism has and continues to place the Bible along side other great epic writings, complete with errors, omissions, myths and legends. Special pleading aside, there is no good reason to place the Bible in any other catagory.
Where did Darwin ever disclaim his theory of Natural Selection?

Unfortuately, one of the tenents of young earth creationism is that the universe, including galaxies and stars, was created in the present state with their light already shining on earth. Of course there is no good reason to believe this other than it is an article of faith with them based on a literal reading of Genesis.

BTW as Eastern Orthodox Christians, we never had any inkling that this was even an issue until recently. What a shock! When I went to a Catholic High School years ago what y'all call theistic evolution was called something like intelliget design. It sure wasn't what it appears to be now.

This is in the news again (Mar 2005), [but the original discovery took place a decade ago].
Your claim reports that amino racemization (AAR) was used to confirm the ancientness of this bone. But this technique can only date back 200,000 years (and not terribly reliable at that).
T.Rex died out 65 Million years ago, so how can AAR prove anything (except that it didn't die recently)? How come radiometric methods haven't been applied, which could settle the ancientness issue properly?
Response
The point of the amino acid racimization analysis was indeed to demonstrate that the organic residue she had extracted was not a recent contaminant. The Hell creek Formation happens to be one of the better dated hunk of rock on the planet. The data below were compiled by Dr. G. Brent Dalrymple, and published (along with many more) in "Radiometeric Dating Does Work!" which can be read at the National Center for Science Education website.
The data are presented in the order of "Material," "Dating Method" "Number of samples," and "Age in Millions of years."
| tektites | 40Ar/39Ar total fusion | 28 | 64.8±0.1 |
| tektites | 40Ar/39Ar age spectrum | 1 | 66.0±0.5 |
| tektite | 40Ar/39Ar age spectrum | 1 | 64.7±0.1 |
| tektites | 40Ar/39Ar total fussion | 17 | 64.8±0.2 |
| biotite, sanidine | K-Ar | 12 | 64.6±1.0 |
| biotite, sanidine | Rb-Sr isochron, (26 D.P.) | 1 | 63.7±0.6 |
| zircon | U-Pb concordia (16 data) | 1 | 63.9±0.8 |
So, the MOR 1125, and MOR 555 femurs happen to be some of the better dated dinosaur bones known to exist. The independently established age of this bone is based on 86 seperate chemical analyses on three different kinds of minerals, based on four independent radiometric decay series. It doesn't get much better than that.

I've put my suggestions in brackets after what you've currently got.
Evolution The fact the frequency of the apperance of alleles in a population of organisms changes over time.
[All the changes that have transformed life on Earth from its earliest beginnings to the diversity that characterizes it today. from Campbell and Reece] At the least, the current version is pretty sloppy.
Allele The pieces of DNA that cause a particular trait, ie. "blue eyes".
[Put in gene, modify allele: Gene A discrete unit of hereditary information, located at a specific place on a certain chromosome, consisting of a specific nucleotide sequence.
Allele An alternative version of a gene. Different alleles are located at the same specific place on homologous chromosomes, but their nucleotide sequences differ.] The current definition is flat out incorrect.

Chapter 7, v11: In the six hundredth year of Noah's life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
And the event ends here:
Chapter 8, v13: And it came to pass in the six hundredth and first year, in the first month, the first day of the month, the waters were dried up from off the earth: and Noah removed the covering of the ark, and looked, and, behold, the face of the ground was dry.
So according to the Bible, the flood begins in Noah 600, month 2, day 17, and ends on Noah 601, month 1, day 1. This is, by my workings, 11 months, 13 days.
Also, note the two statements:
7:24: And the waters prevailed upon the earth an hundred and fifty days.
and
8:3: And the waters returned from off the earth continually: and after the end of the hundred and fifty days the waters were abated.
So the waters remained constant ("prevailed") for 150 days and began to abate after that.
It is sad that people don't actually read the texts they are supposedly defending from us evil science types...

I'll warn you, though. Before you start debating evolution, you'd better know a lot more about it than, in all likelihood, you do now. (Certainly, you should know more than I do; I know enough to know I don't know enough.) Just cutting and pasting some arguments you read in a booklet somewhere probably won't cut it. Until you can really understand and analyze the evidence supporting evolution -- and there are mountains of it -- you'd probably be better off reading more and learning what you can. There's plenty of resources on this site; why not start with the Must-Read Files?
When you decide you're ready to start debating, save yourself some hardship and read the talk.origins Welcome FAQ. Pay close attention to the pointers for debate. And good luck!

Being wrong also helps me be humble (and I need all the help I can get). If I can be wrong about something like prions, then I can be wrong about matters in personal relationships. I have been around people who are right all the time; I do not like to spend time with such people, and I very much do not want to be like them.

Gentry claims that the Po is primordial because many Po centers are not accompanied by uranium which could serve as a long-lived parent (U-238 decays, with a half life of 4.5 Gy, to Pb-206 via a series of intermediate daughters including Po-218). Gentry concludes that the “primordial” Po centers and their host Precambrian granites formed within the first minutes of the Biblical creation 6,000 years ago. That some Po radio-centers are unsupported by U cannot be denied: Neutron irradiation produces no fission tracks; concentric U halos are missing; and the final daughter Pb is free of the 205 isotope derived from U-235.
Gentry argues that the Po was not derived from radon that had diffused from its U parent because he did not identify Radon-222 halos concentric with Po halos (there are usually 3 concentric Po halos from the 3 Po isotopes 218, 214, and 210). But some of his microphotographs clearly show Po halos centered on cracks, and the intersections of cracks, precisely where one would expect microcavities that could accumulate radon gas. Biotite has basal cleavage along which radon could diffuse, and his samples are flaked for viewing.
Gentry erroneously states that fluorite has no cleavage, whereas it actually has perfect octahedral cleavage. Most importantly, the energies of Rn-222 alpha particles, 5.49 MeV, are sufficiently similar to those of Po-210 alpha particles, 5.30 MeV, to render their respective halos indistinguishable. Furthermore, only 5 distinct concentric halos are evident in his micrographs of fully developed U halos, whereas his idealized diagram shows 6. In U-free polonium halos the inner halo is especially intense, as one would expect if it were a superposition of two halos, one due to Rn-222 and the other to Po-210.
Thus, the inability to recognize a separate Rn halo associated with U-free polonium halos is not sufficient evidence against the in-situ derivation of Po from Rn, which could have diffused away from parent U and accumulated within a microcavity. All this does not preclude the possibility that, in rare cases, Rn-derived Po migrated to a center of precipitation of unknown chemical affinity, although its 3-minute half life limits the distance it could have moved.
There is no mystery: Gentry’s polonium is not primordial; it is derived from long-lived U-238 (half life = 4.5Gy) via the diffusion of the inert gas, radon-222 (half life = 3.8 days). Furthermore, geologic mapping shows that one of Gentry’s granites intrudes stromatolite-bearing sedimentary rocks (Wakefield, JGE 1988).

What is the evidence that the rings are entire seasons? Couldn't the rings be caused by monthly or weekly differences in temperature causing some water to be compacted as ice and others as snow?

And the God Darwin believed in towards the latter half of his life was at best the Deist God, an absent God who worked through the laws of nature only. Not that this matters - there have been many theist evolutionary biologists, and Darwin is not an authority in this regard, but as a matter of historical accuracy, Darwin believed in neither the Christian God nor the Bible.

But it doesn't help that many scientists don't know how to articulate the nature of science. There are a considerable number of what can only be called "textbook myths" about "scientific method". Science is in fact a living thing, not entirely capable of being captured by a definition; and so it gets hard to demarcate between science and pseudoscience in ways that could be passed through the limited nozzle, conceptually speaking, of the mass media.

Now consider that the first and most primitive Primates supposedly appeared 60 million years ago—5 million years after the start of the Cretaceous period. The first modern Apes appeared 30 million years ago. Yet, there are ape species on both the African and South American continents.
How is it that genetically compatible apes are native to both continents? I’m not sure if I’m more impressed by the monkey’s swimming abilities or their boat-building skills.
Also: note to the webpage author-- I would be happy to offer a reply to any of your questions that could supposedly stump a creationist (the lists i've seen so far are not even remotely challenging). If, for some reason, you wanted some sort of accreditation I have a Ph.D. in Organic Chemistry from the University of Georgia and a J.D. in Law from Regent University School of Law, so I think you would find me qualified to respond to any technical queries. It's up to you. Bye, everyone.
Response
You need not worry too much about either. Species found on Caribbean islands do suggest some ability to move by "island hopping" and we know that primates today can swim between islands very well. But just as likely was a simple overland route when the North and South American continents became connected. We know by comparison to the Indian, and African plates that the biological 'connections' follow the geological.
What you should consider is the many primates such as Microsyopidae, and Plesiadapidae, which were present in both North America and Europe during the middle Paleocene to late Eocene. In fact, the oldest primate, Purgatorius, was found in North America.
Most South American fossil primates, such as Cebidae, and Callitrichidae, do not appear until the Miocene. Even the earliest South American fossil primate, Branisella, did not appear until the late Oligocene.
Africa was colonized from Europe in the early Oligocene. Similarly, the South American continent doesn't seem to have been colonized by primates until it was "reachable" from North America.
Second verse; There are many authors who contribute to TalkOrigins. There is a quite clear set of submisison guidelines. I suggest that you review them.

Over time, the amounts of Pb-206 and Pb-207 will change in some samples, as these isotopes are decay end-products of uranium decay (U-238 decays to Pb-206, and U-235 decays to Pb-207). This causes the data points to separate from each other. The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time
Why will the amounts not change in all samples, only some?
Response
That quoted text is from my Age of the Earth FAQ, discussing a Pb/Pb isochron diagram for the Solar System. In that diagram, the data point for iron meteorites will never move, because they contain little or no uranium.

When a person claiming to be Christian attempts to appease man-made viewpoints, it results in a compromise of the belief in the Christian God. If you do not believe the Bible to be the literal, inerrant Word of God, how can you claim to agree with Christianity? To take the Bible as literal is a fundamental must of claiming to adhere to the Christian faith. The sad fact is, when Christians try to appease evolutionist scientists by claiming both Creation and Evolution are true, they lose even more respect from evolutionists. Try taking one side and sticking to it, not watering down your belief in God to try and mollify the evolutionists. Trust me, they look at creation-evolution integrators and derisively laugh even harder than they do at Creationists who stick to pure Creationism.

The sad fact is, the largest anti-Christian movement in the United States today is creationism, and is done in the name of Christianity.

“Evolution is thus seen as a series of blind alleys. Some are extremely short - those leading to new genera and and species that either become stable or become extinct. Others are longer - the lines of aadptive isolation within a group such as a class or subclass, which run for tens of millions of years before coming up against their terminal blank wall. Others are still longer - the links that in the past led to the development of the major phyla and their highest representatives; their course is to be reckioned not in tens but in hundreds of millions of years. But all in the long run have terminated blindly. etc. etc. Julian Huxley, “Evolution: The Modern Synthesis” page 571

anyway a quick request. my girlfriend is writing an essay on the impact of evolutionary though on social democracy in early 1900s. anyway she wants a good explanation of the key differences between lamarckism and neo-lamarckism, and then the differences between those and darwinism. I read a bit of the stuff you had in the "So you want to be an anti-darwinist" which was useful, but was wondering if you could outline more of the differences between lamarckism and neo-lamarckism.
thanks for your help and keep up the good work.

(Type 1) Neo-Lamarckian heredity
This actually appears in Darwin's own writings in two sub-varieties. The first is that traits that get used in a modified form will tend to be passed on due to some hereditary process, while those that do not will tend not to be passed on and will wither away over generations. This is use-and-disuse. Soft-inheritance or the 'inheritance of acquired characteristics' is the idea that changes accrued during an organism's life are passed on to their progeny. While Lamarck held the soft-inheritance view, this was well before Weismann introduced what Mayr later called "hard inheritance".
(Type 2) Directed variation
A second sense of Lamarckism is the idea that variations arise to anticipate or meet needs. This is not what Lamarck thought. Instead he thought that variations were brought about to deal with present needs as a result of the action of the local environment upon the underlying biology of the organism. How this happened was never really clear.
(Type 3) The progressive evolution of complexity
Lamarck and many since (e.g., Teilhard) thought that evolution is an inevitable increase in some measure that is progressive. It might be increasing in 'perfection', 'complexity', 'consciousness' or whatever. It is widely accepted that Darwinian evolution is no guarantee of progressiveness on any measure. Even the existence of an objective scale is open to question.
Neo-Lamarckians adopted types 1 and 3 more or less unreservedly, in the period known as the "Eclipse of Darwinism" from around 1880 to 1920 or so. They occasionally also accepted type 3. It is important when discussing these ideas that you disambiguate them, or confusion will result.
