Humans are STILL evolving, say experts who found an artery that is lost at ...

A new study suggests humans are still evolving and 'at a faster rate than at any point in the past 250 years'.

Scientists found an increase prevalence of an artery in the forearm, which typically disappears around eight weeks after birth, since the late 19th century.

Called the median artery, as the structure begins to disappear, two other arteries form in its place – but there has been an increase of cases with all three.

The prevalence began around the 1880s in 10 percent of the population, but by the 20th century, the cases increased to 30 percent.

The team found this vessel is currently present in 35 percent of people and theorizes those born 80 years from now will carry a median artery.

The discovery was made by experts at Flinders University and the University of Adelaide.

The median artery is an important vessel in the embryogenic circulation, bringing blood through the forearm and hand.

Following birth, the artery recedes and is replaced by the radial and the ulnar arteries.

Dr Teghan Lucas at Flinders University, said: 'Since the 18th century, anatomists have been studying the prevalence of this artery in adults and our study shows it's clearly increasing.'

'The prevalence was around 10 percent in people born in the mid-1880s compared to 30% in those born in the late 20th century, so that's a significant increase in a fairly short period of time, when it comes to evolution.'

'This increase could have resulted from mutations of genes involved in median artery development or health problems in mothers during pregnancy, or both actually.'

'If this trend continues, a majority of people will have median artery of the forearm by 2100.'

The team suggests the presence of the median artery benefits because it increases overall blood supply and can be used as a replacement in surgical procedures in other parts of the human body.

And they refer to this as 'micro evolution' in humans.

Senior author Professor Maciej Henneberg, of the University of Adelaide, said: 'the median artery is a perfect example of how we are still evolving because people born more recently have a higher prevalence of this
