Future humans -- more attractive, more intelligent, more nurturing?

I’m generally a fan of the physicist Michio Kaku. I enjoy his speculations about the future of humanity, his realistic optimism, and his willingness to speculate about ideas from the realm of science-fiction. But recently, I watched a short video in which Dr. Kaku explained some of his ideas about evolution, and I found myself strongly disagreeing with a number of his points.
