Your brain is one of the most important human features evolved by natural selection. ( perhaps sexual selection also had something to do with it )

Camouflage is a beneficial feature that evolved through natural selection, as it allows organisms to blend in with their environment and escape predators. This adaptation increases an individual's chances of survival and reproductive success, ultimately leading to its increased prevalence in the population over time.
The Archaeopteryx evolved through natural selection by inheriting beneficial traits that aided in survival and reproduction, such as feathers for insulation and flight. Individuals with these advantageous traits were more likely to survive and pass on their genes to offspring, leading to the evolutionary development of the Archaeopteryx.
All animals, including Homo sapiens, did and do.
Sexual reproduction has evolved because it increases genetic diversity in a population, which can enhance the ability of offspring to adapt to changing environments. It also allows for the removal of harmful mutations through recombination and provides an opportunity for natural selection to act on beneficial traits.
