Fossils - Window To The Past (Home)
Why would you think there would be a preserved fossil for every animal that ever walked the earth?
I would think there would be a transitional fossil for every major group that crossed over.
The point gould and eldredge made was there was no change at all.
Thats not what they said at all. What they said was there were evolutionary changes then a stasis of evolution for a long period of time, then a change again.
They appear suddenly with no change ?
Punctuated equilibrium: come of age?
by Dr Don Batten
The concept of punctuated equilibrium (PE) is explained. The development of the idea since its inception by Stephen Gould and Niles Eldredge is traced, as well as some of the controversies. PE consists of two aspects:
(1) an observation—that the fossil record is characterised by
(a) abrupt appearance of species, and
(b) stasis, or lack of substantial change, throughout a speciesÂ’ range in the fossil record; and
(2) a theoretical attempt to explain how this pattern can fit an evolutionary (naturalistic) model for the origin of species.
Gould and Eldredge claimed that the abrupt appearance of species could be explained by the transition occurring quickly, geologically speaking, in small, isolated populations such that the transitional forms would be highly unlikely to be preserved. They claimed that this theory arose out of biology, but there is no empirical biological basis for such speciation events. It seems that the ‘mechanism’ was adopted because it ‘explained’ their observation of the fossils (they are both palaeontologists). Gould gave air to ideas of macromutational change to explain major transitions and fueled perceptions that PE’s rapid speciation was a form of ‘hopeful monsters’ evolution. Gould and Eldredge denied that this is what they meant.
The debate over PE has given publicity to stasis as a serious problem for evolution (how can you believe in evolution, or change, when the fossils testify to stasis, or lack of change?). The recognition of the reality of abrupt appearance and stasis corroborates what creationists have been saying since Darwin—that the evidence fits special creation combined with the results of a worldwide Flood. In this context, Wise’s ‘punc eq creation style’ is also discussed.
