Charles Darwin’s theory of evolution postulates that organisms change over time as a result of changes in heritable physical or behavioral traits. Beneficial changes that better enable an organism to adapt help it survive and produce offspring that might carry the same traits.
Since Darwin released his book On The Origin of Species in 1859, evolution by natural selection has been supported by evidence from geology, paleontology, biology, and genetics; now it’s one of the best substantiated theories in the whole history of science. But despite the overwhelming confirmation, a 2014 Gallup Poll showed that a whopping 73 percent of Americans still subscribed to one form of creationism or another. So to help those people understand that humans didn’t just magically arrive in their present form 10,000 years ago, here’s a list of seven ways that science has validated the theory of evolution.
7. The Examination of Embryo Development
If you take a look at the growth of a human mbryo and compare it with other species such as fish and reptiles, it becomes apparent that they all look similar at certain stages in their development. This is because, even though their evolutionary paths diverged millions of years ago, they still all have some ancient genes in common. These genes date back all the way to the origins of cellular life and they’re the reason why early human embryos feature tails and have a lot in common with fish embryos.http://www.theguardian.com/science/2015/jan/30/experts-urge-uk-permit-ivf-procedure-prevent-fatal-genetic-diseases-mitochondrial Via The Guardian
