What I've posted below is from a thread in another place where I discussed this question and asked for additional examples. The examples are from others who discussed this topic.
I've been learning a lot of neat stuff about how we know what we know about evolution in some recent threads (the evidence trail). It made me want to get a handle on what we would actually expect to find in our world if young earth creationism with noachic flood were true.
Geologic Record
We would expect one massive worldwide sedimentary event that is very homogenous
Geographical Distribution of Species
the distribution of species on the planet should be governed largely by the Noah's Flood event.
We would expect that the slowest species be closer to the Middle East, while the fastest species be distributed throughout the world. Further, we expect to see distributions in radial lines extending from the middle east to more distant parts of the world (as stragglers got left behind during the journey).
For example, if all marsupials made the journey from the Middle East to Australia, then to South/North America, then we would expect to see straggler species distributed along the path they took in migrating to Australia.
Fossil Record
the overwhelming majority of fossils are arranged by Noah's Flood. Virtually every living thing would have been fossilized, so we would have an extremely complete record of all the animals that were alive at the time of Noah's flood.
The churning of the ocean's floor would have been so violent that there would be no sorting of the animals drowned by Noah's Flood.
The conditions of the Flood should have preserved nearly all individuals alive at the time, so the great majority of fossils we find should be from the time of the Flood (an event spanning some 40 days or so, a blink in the geological eye), and these would all be in a homogeneous sedimentary layer of a single age.
We would see fossils form very quickly, in less than 6,000 years. Such that any fossil NOT in the Noachic layer must be a younger fossil and will show the rate of fossilization.
We'd know that fossils are all younger than 6000 years, so all should still have DNA and/or large amounts of carbon.
Furthermore, the mix of species before the flood should have remained fairly constant. The only sorting we should see in the fossil record is that certain species existed before the flood, but not after the flood. No other major extinction events should exist other than the flood.
Genetics
Life is organized into "kinds" (needs definition). Each "kind" was created completely separately, and thus we expect to find great similarities within "kinds", but vast differences between kinds because kinds are not related to each other at all.
We would expect to see the same rate of genetic differentiation now as we infer from the Noachic fossil record until now. However the "kinds" have changed since the flood, we expect they would continue changing at that rate.
We would see massive mutation rates. Getting from no more than 10 HLA-B alleles to over 620 alleles in less than 6000 years. So we're talking a minimum of one obviously beneficial mutation per generation (assuming a generation time of ten years).
That's in addition to all the other multiple allele genes within human systems.
It's much worse for some animal 'kinds'. As you have to get hundreds of alleles from a max of 4 alleles.
Embryology
Creation theory tells us that "kinds" are distinct and that if we compare embryos between species of different "kinds" should not have similarities.
For example, would human, rabbit, and chicken embryos have gill slits very early in development? Would we expect to see animals without tails have embryonic tails that disappear?
...
So my question is - why do we not see the evidence we would expect to see if all animal kinds were created separately 6000 years ago, and bottlenecked to fewer than 7 examples of each at about 4000 years ago and re-dispersed after that?
Or - DO we see the evidence we would expect to see if all animals were dispersed from 7 or fewer individuals only 4000 years ago from a single geographical location in the middle east?
by the way, I would like to cite the contributors directly, but the terms of service of this site prohibit me from linking to the original contributors. If you wish to search on the text, you'll find it.
