This Forearm Artery Shows Our Species Is Still Evolving

KEY POINTS

  • The study shows a significant increase in the prevalence of median artery in humans in the past 250 years
  • The artery usually disappears during developmental stages in the womb
  • Researchers say its prevalence in adults suggests that humans are still evolving

Humans are still evolving and are doing so at a faster rate than before, shows a new study. The evidence backing this “microevolution” can be found in people’s forearms.

When talking about evolution, people tend to think of it as something that happened in the past and perhaps of changes that are quite drastic such as aquatic creatures developing legs to walk on land. But a study by researchers from the University of Adelaide and Flinders University, both in Australia, found that humans are still evolving in small ways that are not easily observed.

The new study, published in the Journal of Anatomy, analyzed the prevalence of
