Lots of animals share similar DNA.
I truly believe we are made in the image of God. Not some ape.
Evolution is full of speculation. I see no real hard facts myself.
It's really about more than just similar looking DNA. It's also DNA that has differences which make genomes look as if they descended from a common ancestor.
For example, let's say you have a fish with genes AAAA. And you have an amphibian with DNA AAAT. You might consider that the two are related, as their DNA appears to depict the occurance of a point mutation. It isn't the similarity that we are looking at, rather it's the difference. It Is the mutation that we look at. Just the same, a reptile with DNA AACT would be considered more distant in relation to the fish because there are more
difference in their genome.
It's relatedness via differences
that look like changes made by mutations.
As if they are related.
The same goes with a paternity test. If a woman wants to know the father of her child, they look for differences in DNA that suggest ancestry and modification as a product of mutations.
And those differences look
as if they were a product of mutation.
Thankfully we can observe mutations and changes in DNA in the present time, so it isn't a mystery to us how those differences from the ancestral genome came to be.
Until someone has a logical argument against paternity tests, they don't really have ground to argue that say alligators and crocodiles aren't related or ostriches and penguins or wolves and tigers etc. Because common ancestry between all these animals is concluded in the exact same way that paternity tests are.
And this only makes sense in light of common descent. If I were a young earth creationist, I'd have no reason to believe that a flowering plant or seeded plant shared more or less differences in DNA to non vascular plants. I also would have no understanding of why plants appear in order in the fossil record to begin with.
Can any young earther explain why non vasculars predate vasculars which predate seeded which predate flowering? No, they can't.
At best Creationists will tell you that flowering plants ran away from flood waters to higher ground faster than seeded plants, or that flood waters deposited fossils of the earth in an order based on differences in their DNA.
Or they might say that aquatic animals predated land based animals, while simultaneously ignoring species like whales which came after land animals and of course whales have shared DNA differences with hippos and appear in the fossil record at the same time as ungulates (hippos, giraffes etc). But it's just some fluke where the flood waters happened to deposit prehistoric whales right near land based ungulates in some sort of bizarre coincidence of the fossil record.
