Human Nurture - Feral Children

Learning about feral children, and especially seeing the video of the feral girl from Ukraine who was raised by dogs and adopted their traits, made me realize just how much of our human behavior is learned. The girl walked around on all fours and even panted. Dogs pant because they can't sweat; that girl had sweat glands, but just chose to pant. You'd think that something like that is natural, but apparently even panting is learned behavior.

It's also interesting that once brought back into society, they began re-adapting quickly. But the feral children were still most comfortable acting like they were raised. This shows us that after the first five or so years of one's life, their brain stops absorbing information at the rate that it had done so earlier.
