“New mutations don't create new species; they create offspring that are impaired.”

“Natural selection eliminates and maybe maintains, but it doesn't create... Neo-Darwinists say that new species emerge when mutations occur and modify an organism. I was taught over and over again that the accumulation of random mutations led to evolutionary change [which] led to new species. I believed it until I looked for evidence.”

“Evolution is no linear family tree, but change in the single multidimensional being that has grown to cover the entire surface of Earth.”
