A Few Thoughts on ID - Part I. The Fossil Record
This post is very long, so I am going to break it into three parts. To get it into the proper order on the page, Part 3 was posted 1st, Part 2 2nd, and Part 1 3rd. Hence the apparent contradiction in the time stamps is an artifact of ensuring a convenient reading experience.
Part I. The Fossil Record
Part II. The Age Of The Earth
Part III. Religion In The Classroom
IDers frequently complain that the fossil record fails to contain evidentiary link of the evolution of “man from ape.” This argument is disingenuous as it shows a complete lack of understanding of what the theory of evolution says. Man did not evolve from extant species of apes, rather, man and ape share a common ancestor. Thus, the fossil record would never show intermediary species between human and ape. What it would (and does) show is a progression backwards from both species to intermediary forms sharing increasingly (as time goes backwards) similar traits.
In other words, the theory of evolution states that millions of years ago, there was a species B that due to environmental pressures and random mutations became two nearly identical species, B’ and B’’ which occupied similar, but slightly different, habitats. As time went on, B’ and B’’ (also through environmental pressures and random mutations) further differentiated themselves (i.e. widened the gap of similarity). This process ultimately resulted in two completely new species, AB and BC, along with numerous intermediary forms, b, b’, b’’, etc. that became extinct because they could not adapt or compete.
What did survive, however, was species AB, which displayed predominantly human-like traits, and species BC which displayed predominantly ape-like traits. As the evolutionary process continued in the same manner as above, AB evolved into modern humans (A) and modern apes (C). Actually, I think species C is either orangutans or rhesus monkeys. Again, I’m not an expert, I just read a lot. Either way, the point is that there would not be a direct intermediary path between species A and C.
What galls me is that the IDers refuse to acknowledge that this is what evolution teaches, and instead insist that without the direct link between A and C, it “proves” that evolution is wrong. Even were they to argue in good faith that there were gaps in the intermediary forms, it would not disprove evolution. The fact that there are gaps in the evolutionary record is not half as surprising as the fact that there are so many “slots” on the path that are actually filled in. It takes very precise conditions for a fossil to result from the bones of a dead creature. Ravages of time and weather further decrease the likelihood that any particular fossil will even survive the intervening millennia such that it can be found. I think that a fossil is much like making a cheesecake: it takes very specific conditions to come out right, but when it does, the result is spectacular.
