Complex Animals Led to More Oxygen, Says Maverick Theory
...Darwinian evolution needed time to arrive at that tipping point. “The gene regulatory network to build an animal is the most complex algorithm that evolution has ever produced,” he said....
What’s in a Name? Taxonomy Problems Vex Biologists

What Is Life?
...Not think about chemistry or geology or physics or astronomy, biology as separate things. But it’s one interconnected web, in which we see this amazing process of evolution, evolution of...
