Thanks on
behalf of TalkOrigins for your kind words.
I can make two responces to your query about abiogensis,
the first you have already heard and found unsatifying. But
the fact is that evolutionary biology does not rest on the
origin of life as it is expressly the theory of the
diversity of life as we find it. Now at the same time, I
agree with you (and Darwin) that the notion of common
decent can logically imply a single "First Common
Ancestor."
Darwin had this to say about the origin of life in his
Origin of Species.
“ I believe that animals are descended from at
most only four or five progenitors, and plants from an
equal or lessor number.
Analogy would lead me one step farther, namely, to the
belief that all animals and plants are descended from some
one prototype. But analogy may be a deceitful guide.
Nevertheless all living things have much in common, in
their chemical composition, their cellular structure, their
laws of growth, and their liability to injurious
influences. ...
Therefore, on the principle of natural selection with
the divergence of character, it does not seem incredible
that, from some such low and intermediate form, both
animals and plants may have been developed; and, if we
admit this, we must likewise admit that all the organic
beings which have ever lived on this earth may be descended
from some one primordial form. But this inference is
chiefly grounded on analogy, and it is immaterial whether
or not it be accepted. No doubt it is possible, as Mr. G.
H. Lewes has urged, that at the first commencement of life
many different forms were evolved; but if so, we may
conclude that only a very few have left modified
descendants.”
Since the 1970s, the majority of funding in this area
has come from NASA as part of its exobiology program. In
fact, very few individuals can devote their professional
careers to research on the origin of life, and they are
scattered in various sciences that do not always
communicate well with one another. The Scripts Institute in
La Joya, California is one locus of active research with
three or four of the top names in the field. But, even with
a relatively low level of funding there is a prodigious
amount of relevant material published. This leads to the
next response to your question.
In order to be reasonably current with abiogensis
research one must read the relevant geochemical, molecular
biological, and astronomical research. And, to be
particularly germane to TalkOrigins, one must also read the
creatonists' "scholarship" on the topic. This includes
their classics, such as C. B. Thaxton, Walter L. Bradley,
and R. L. Olsen, "The Mystery of Life’s
Origin." (1984 New York: Philosophical Library) and
more recent books such as, Fazale Rana, and Hugh Ross
"Origins of Life: Biblical and Evolutionary Models Face
Off" (2004 Colorado Springs: NavPress). There are also
dozens of creationist "research" publications that present
their reactions the published science.
The bibliography I have collected on this topic is
running about 45 pages long, and represents 3 to 4 thousand
pages read as of today. Now, this is minuscule compared to
the amount published on any of the dozens of subdisciplines
related to evolution per se. Actually, it is a
minuscule part of the relevant research on abiogensis. I am
toying with the idea that it is about time to stop reading
and start writing. Your nudge might be enough, in which
case thanks again. I think ...
The most current book that presents origin of life
research to the general reader that I recommend is Iris
Fry, "The Emergence of Life on Earth: A Historical and
Scientific Overview" (2000 Rutgers University
Press).
