2. Even if true, this isn't all that surprising. While we're all familiar with the simple linear evolutionary projections we see in elementary school textbooks, the fossil record is much more complex, filled with branches, dead ends, hybridization and other weird stuff. It's often hard to figure out the exact evolutionary path from a series of specimens.
I like your tag line, and how true that really is, we only think that gravity is the real ldeal, but at sometime in the future someone may show that it really doesn’t even exist but what attracts bodies is something different.
Ain't that the truth. Lies lead to deadends.
