About the book: 2020 / When and why did our ancestors lose their wool? And did you really lose it? Why are we not naked and aquatic, but rather sweating monkeys? How many crazy hypotheses have been proposed to explain our hairlessness, and why has the question remained open? What can lice and fleas tell us about human evolution? How did skin color change during evolution: did our ancestors lighten or darken? Or maybe they darkened first and then brightened? What was all this leapfrog and what do Neanderthals have to do with it? Why do lemurs have blue eyes and macaques have bald heads? Is it true that a beard does not attract women, but intimidates men? Alexander Sokolov, editor of the ANTHROPOGENES.RU portal, talks about this and much more in his book, once again proving that science is incredibly interesting and sometimes paradoxical.
