Physical characteristics known as structural adaptations assist an organism in surviving and procreating in its environment. Our hands, along with those of other primates, are one of our best adaptations. We were able to use tools and construct elaborate shelters and other structures thanks to our hands.
We have been able to live in a wide variety of environments and temperatures because to three adaptations: our bipedalism (the capacity to walk on two feet), opposable thumbs (which can touch the fingers of the same hand), and complex brains (which oversee all we do).
Through the course of human history, humans have also evolved biologically as a result of these adaptations as well as several environmental variables. Biological adaptations include acquiring opposable thumbs, larger, more developed lungs, the ability to stand up straight, and larger brains.
