The process of biological evolution often allows humans to survive consistent environmental stresses that occur across multiple generations. As humans colonized Earth's diverse environments, they encountered hot, dry areas and decided to settle. What trait likely offered an advantage in this environment?

A) the ability to squint eyes to block out bright light
B) the ability to dig deep holes to find groundwater
C) the ability to shiver to create body heat
D) the ability to produce sweat to cool their bodies

An advantage for the humans in hot, dry areas has been the ability to produce sweat to cool their bodies.

Explanation:

The humans may seem as a species that lacks adaptations for living in nature successfully nowadays, but that is far from true. Our species has developed lot of traits over the course of millions of years in order to be able to survive in all types of environment, making it a species that is very flexible, and can develop traits in relatively short period of time. The fast development of advantageous traits have provided the humans with the ability to live pretty much everywhere on the planet.

In this case, we have the hot, dry environment. While the majority of the species, especially the medium sized and large ones, either can not survive, or struggle to do so, the humans thrived. One of the main evolutionary adaptations that enable that are the sweating glands. Unlike most of the animals, the humans have sweating glands all over their body, and that is of huge help in hot environments because the body is cooled off much more efficiently, so the humans don't suffer from overheating, or rather they are much more tolerant to these conditions than most of the other animals.

Some other adaptations developed by the humans because of the climate conditions are:

  • reduced sweating glands among the east-Eurasians
  • wider nostrils at higher latitudes, smaller nostrils at low and cold latitudes
  • different pigmentation of the skin
  • reduction of the body hair
