Modern medicine has completely changed our lives, but I hadn't considered it could be changing human evolution in the long term.

A study has found that more women are needing Caesarean births as their hips are too small, compared with 50 years ago. Before Caesareans, women with smaller hips wouldn't have survived childbirth. Today they can, and they then pass their 'small hip' genes on to their children.

This could be one of many changes we see in future humans. Our amazing medicine makes us healthier, but our descendants could need more treatment as a result.
