Why are humans growing an extra artery?
Lucas explained in a conversation with ScienceAlert, “This increase could have resulted from mutations of genes involved in median artery development or health problems in mothers during pregnancy, or both actually.”
Why are babies being born with an extra artery?
Modern babies are being born without wisdom teeth as humans continue to evolve at a rapid rate, a study has found. In addition to that, they seem to have an extra artery in their arm as a result of a human “microevolution” in recent years.
Can humans grow new blood vessels?
we never lose the ability to grow new blood vessels.
Are we still evolving as humans?
Natural selection doesn’t really care about survival.” And, a 2010 paper by Alan R. Templeton preemptively discarded Attenborough’s theory that physical evolution has been replaced by cultural evolution, arguing instead that “all organisms adapt to their environment, and humans are no exception.

Are humans being born without wisdom teeth?
Not everyone has to hassle with wisdom teeth. Some people aren’t born with a complete set and studies have shown that approximately a third of people are born without any. And while some people may have the teeth, they never see them emerge.
Do I have an extra artery in my forearm?
New research in Australia has confirmed that more and more adults have a median artery in their forearms. Or, more accurately, they have retained the median artery. It is the main vessel that supplies blood to the forearm and hand in the womb, but usually disappears once the radial and ulnar arteries develop.
What is extra artery?
The extra artery is a median artery that’s first formed in the womb and serves as the main vessel that supplies blood to the forearm and hand, according to Sky News. The median artery vanishes once the radial and ulnal arteries develop, though now one in three people keep it for life.
What is the extra artery in your arm?
The extra artery is a median artery that’s first formed in the womb and serves as the main vessel that supplies blood to the forearm and hand, according to Sky News. The median artery vanishes once the radial and ulnal arteries develop, though now one in three people keep it for life.
When does the median artery form?
The median artery forms fairly early in development in all humans, transporting blood down the center of our arms to feed our growing hands. At around eight weeks, it usually regresses, leaving the task to two other vessels – the radial (which we can feel when we take a person’s pulse) and the ulnar arteries.
Are babies being born without wisdom teeth and an extra artery?
Humans are undergoing a “microevolution” resulting in babies being born without wisdom teeth and with an extra artery in their arm, according to Australian researchers.
