These two articles highlight that humans show evidence of natural selection. The Tibetans and those who live in high elevations show genetic changes in their ability to carry oxygen. Native Siberian populations show changes in their genes to adapt to colder temperatures and better maintain homeostasis in the frigid temperatures.
"identified one previously known cold-adaptive gene, UCP1, which helps body fat directly produce heat, as well as two new genes: PRKG1, which is involved in preventing heat loss, and ENPP7, which plays a role in metabolizing fats."
What do you think of these adaptations? What other populations or regions should scientists look for other differences in maintaining homeostasis?
