Why did quadripedal life evolve so much earlier and more wide spread then bipideal life?
Ik bipedal forms are better at long distance and energy conservation but I also know predation came super early in evolution so it's not like a chase down predators did not have a niche. Is it because the skills to make chase down hunting truly special require larger brains like group hunts and tool use. I am just curious. I am also aware of animals like birds and their ancestors that are/were bipedal but the vast majority of animals are quadripeads
