Chloe’s Chat: Human adaptations amaze

I am continuously amazed by the many biological adaptations of the human race, and find myself delving deeper and deeper into the “why’s” or “how’s” of human diversity.

I’m especially intrigued to further my knowledge and argument of why “race” is a social construct and is not a valid biological category, and therefore shouldn’t be used as such.

Our appearances differ only in that we adapted to our specific climates, and it has nothing to do with superiority, inferiority or the like. These differences between us are based around hot and cold climates.

An important job of the human nose is to warm and humidify the air we breathe in. Homo sapiens who adapted in hot climates have wider nostrils in order to do that. Homo sapiens who adapted in colder climates have narrower nostrils in order to warm up the air that travels through their nose.

Another fantastic example of how our climate formed our bodies is that when living things are more compact, they tend to conserve heat, due to a high mass to surface area ratio. While in vice versa, when living things are more linear, they tend to lose heat. This is the reason why people of African heritage tend to be taller than people of European or Inuit lineage.

Our differences are not because we are of different “races.” Our differences are from our biological adaptations to the climates and areas we chose to survive in.
