Human 'microevolution' sees people born without wisdom teeth and extra artery
- instance 6y agoHere's the paper related to that artery for anyone interested: https://sci-hub.se/https://onlinelibrary.wiley.com/doi/abs/10.1111/joa.13224 https://sci-hub.se/https://onlinelibrary.wiley.com/doi/abs/1... They predict that all people in 80 years are going to carry that median artery. So in the span of like 200 years we will have evolved to include this artery.
- rahimnathwani 6y agoThe article suggests the cause is evolution/genes, not environmental conditions such as infection: "The observed increase therefore in the prevalence of persistent median arteries in adult forearms of people in many countries may be a trend associated with the evolutionary process." If I'm reading the paper correctly, they're not suggesting that this is because the artery provides some survival or reproductive advantage. They're just saying the trend is likely to continue.
- sschueller 6y agoHow does one check if one has this extra artery?
- rahimnathwani 6y agoYou don't. The method they used is very invasive, so used only on dead bodies.

- kps 6y agoYup. Genes can't think long-term, so they foolishly made us smarter than they are.
