How Far Have We Come, Really?
Theories on evolution have existed since ancient times, with Ancient Greek philosophers like Aristotle speculating that organisms grew and changed in accordance to some divine cosmic order. Throughout the 18th and 19th centuries, more theories arose that attempted to explain the evolutionary change of species strictly according to science and not religion, and our entire understanding of the process changed when Charles Darwin introduced his theory of natural selection.
According to Darwin, growth in population on the planet leads to a “struggle for existence” in which species must adapt to changing conditions in order to survive, thus leading to more advanced and well-suited physiologies.
Though some people still contest the reality of evolution, and while it takes place over such long periods of time as to make it hard to observe, there is proof of evolution right in your own body. The presence or absence of certain inherited physical traits that serve no clear purpose are our biggest indicators that we are the product of the lengthy process of evolution, and that our own species is slowly but surely adapting to our society and planet’s changing conditions.
Don’t believe us? Chances are you have plenty of vestigial traits, or organs and behaviors that have lost their function due to evolution. Just look at yourself in the mirror…
Here’s some of the clearest evolutionary proof on your own body!
