- .. of Richard Thompson's _Mechanistic and Nonmechanistic Science_
-
-
- Chapter 8, "The Doctrine of Evolution", argues that the Science of
- Evolution has never been successful in providing a reasonable basis
- for a natural explanation of the origin of species. It uses several
- tactics, most of them distressingly familiar.
-
- Briefly, we have the gaps in the fossil record, the argument from
- amazing design, the hopeful monster as scientific desperation, and the
- argument from negative theology. The only new idea, to me, at least,
- is an argument that claims that there are displaced fossils of "higher
- plants" that contradicts the claimed order of evolution theory.
- If they are true, they would through some serious doubt on the descent
- claimed for flowering plants. I will cover this one first, and invite
- all comments. I will then cover the rest of the items briefly in future
- posts.
-
- Thompson starts out with some statements to the effect that there is
- none of the continuity in the fossil record that is claimed by Evolution.
- I think that he is referring mainly to the large scale characteristics,
- as opposed to intra-species changes. "Even such important general pattern
- as the basic vertebrate body plan are seen to appear suddenly in the
- fossil record without recognizable antecedents." [p.187] He then
- goes on to talk about the sudden appearance of angiosperms in the
- fossils during the Albian and Cenomanian Epochs (about 100 mya).
- During this period of 12 million years, the number of families of
- angiosperms goes from 0 to 50. He says that this seems to be "'punctuated
- equilibrium' with a vengeance." [p. 188] He says that many paleontologists
- believe that the angiosperms evolved in relative isolation in some as
- yet unknown place for many millions of years, and then proliferated
- throughout the world sometime in the late Cretaceous. Thompson quotes
- Daniel Axelrod (from _The Evolution of Flowering Plants_) suggestion
- that the evolution of flowering plants took place in highlands, which
- are not represented in very old fossil beds due to severe erosion
- effects. Thompson takes umbrage at this suggestion. He says, "it is
- completely unscientific for paleontologists to try to save the theory of
- evolution by maintaining that they evolved there. If this procedure is
- allowed, then the theory of evolution becomes unfalsifiable.... Such
- vacuous proposals can explain anything, but for this very reason they have no
- place in a scientific account of this world." [p.190] Ironically, later
- on Thompson will claim that the realm of science needs to be expanded to
- include Vedic beliefs as principles and theories! How such claims as the
- existence of the jivatma (the Vedic "soul") are to be made falsifiable
- is not presented.
-
- Next, Thompson drops his coup de theatre - "what would [paleontologists] say
- about evidence for the existence of flowering plants...two billion years
- ago? ... Yet there is evidence that flowering plants may have existed
- during this time [the Pre-Cambrian]." [p.191] He then quotes "Nature"
- as claiming that angiosperm pollen has been found in rock dated to ages
- of 2,090 mya and 1,710 mya.* He also cites an Axelrod paper ["Evolution of
- the Psilophyte Paleoflora," pp. 264-275, journal of "Evolution", 1959 (I
- don't have a vol.#/month)] that mentions claims that spores and wood
- fragments were found from the Cambrian Period. Apparently, Axelrod
- has some theories that run (or ran; how long ago was Axelrod's last
- contribution to the field?) counter to other more popular theories.
- Is anybody familiar with him?
-
- Thompson concludes this section with the claim that the fossil record
- is used to support "unverifiable hypotheses", and that there are "cases
- where evidence conflicting with established evolutionary scenarios seems to
- have been ignored, or even suppressed." [p.192] Now where have we heard
- that before?
-
- This constitutes Thompson's entire argument against Evolution proper.

- *I see that I made a fatal mistake by not copying the bibliography, so
- my citations are more than a little lacking. Perhaps we can persuade
- KD to provide the complete citations. If he/she/it/they feels that
- biblio ref's also require Author Perm's, then I will try to get back
- to the Library for the missing pieces.
- We lack:
- Axelrod, _The Evolution of Flowering Plants_ (presumable a book)
- and Axelrod, "Evolution of the Psilophyte Paleoflora" from the
- journal "Evolution" sometime in 1959.
- and several "Nature" citations, corresponding to notes 15, 16 and 17 of
- chapter 8.
