Various articles touting evolution in action have been circulating through social media, claiming that the rise of c-sections due to the size limitations of smaller female pelvises is an example of the upward evolution of our species.
While this is an excellent example of natural selection (which is observable), it is not an example of evolution (acquiring beneficial traits that lead to a more complex and highly developed species).
These articles point out that more women are losing the ability to give birth naturally. Without medical intervention, most of these women and babies would lose their lives. This is not a beneficial trait to pass on to offspring, and is therefore not an example of upward evolution.
It would instead, unchecked, lead to extinction.
