Claim CC250:

The fossil record does not show the origin of any group of modern plants from its beginning.

Morris, Henry M., 1974. Scientific Creationism, Green Forest, AR: Master Books, pp. 86-87.

Response:

  1. The fossil record shows the origins of several groups of modern plants. The groups listed here are some of the most prominent:

    1. Land plants. Several fossils exist showing their origin (Bateman et al. 1998; Kenrick and Crane 1997). Molecular data combined with the fossil evidence shows that the first land plants were liverworts (Qiu et al. 1998). A fossil Ordovician fungus (about 460 million years ago) has the same form as modern arbuscular mycorrhizal fungi, indicating that the earliest land plants had this kind of symbiotic relationship with fungi (Redecker et al. 2000).

    2. Seed plants. The first trees were also among the first free-sporing plants sharing characteristics with seed plants (Meyer-Berthaud et al. 1999).

    3. Angiosperms. Jurassic fossils of Archaefructus show some of the earliest and most primitive angiosperms (Sun et al. 2002). Ren (1998) described some Jurassic flies adapted for pollination, suggesting that angiosperms may have originated by then. Dilcher (2000) briefly reviews angiosperm paleobotany. Major events in their evolution were the appearance of closed carpels, bilaterally symmetrical flowers, and large fruits.

    4. Monocotyledons. The early fossils of this group are meager, but some fossils exist (Gandolfo et al. 1998).
