Did you write all that yourself?
No, it was probably the same idiots who wrote this:
Huge predators would have lurked in Tiktaalik's rivers and lakes, study co-leader Shubin says—perhaps one reason why Tiktaalik appears to have been headed for land.
"Land had no predators, and it also had food in the form of invertebrates," Shubin said. "Put this all together and the shallows and mudflats might have been a good place to make a living."
Supposedly learned individuals put out this drivel and then other supposedly learned individuals soak it up like sponges...
