The long length of human hair compared to other primates may be the result of sexual selection.

“It could have been sexual selection. It could have been that human populations around the world just liked it. They just thought it was pretty and they chose partners who were able to grow longer hair.”

The aesthetic human preference for symmetry and centering is an evolutionary trait linked to the high-skill requirements for ancestral human survival.

“humans that enjoyed things like hey look, this is symmetric or this is centered did better when it came to surviving with such soft fleshy bodies.”

Breast size is not a factor in how much milk a woman can produce.

“Although your breasts will likely grow larger before and during your breastfeeding journey, breast size is irrelevant when it comes to how much milk you produce. A mom with small breasts might have just as much milk supply as a mom with large breasts.”
