Fast Track ~ Evolution: More People Being Born Without Wisdom Teeth & An Extra Artery (Page 1/2) Boondawg OCT 09, 08:10 PM More people are being born without wisdom teeth and an extra artery in their arm as a result of a human "microevolution" in recent years, a study has found. Babies now have shorter faces, smaller jaws and extra bones in their legs and feet, a study in the Journal of Anatomy found. Australian researchers who worked on the paper claim the human race is evolving faster than it has done at any point in the past 250 years. Over time, human faces have got shorter, which has seen our mouths get smaller, with less room for as many teeth. As part of natural selection and our increased ability to chew food, this has resulted in fewer people being born with wisdom teeth, Dr Teghan Lucas from Flinders University, Adelaide, said. "A lot of people thought humans have stopped evolving. But our study shows we are still evolving - faster than at any point in the past 250 years," she added. An artery in the forearm that supplies blood to the hand has become more prevalent in newborns since the 19th century, the study also found. The median artery used to form in the womb but disappear after the baby was born and the radial and ulna arteries had grown. Now, one in three people keep their median arteries for their whole lives, which poses no health risk and increases blood supply to the hand. Author Professor Maciej Henneberg said: "This is 'micro evolution' in modern humans. "The median artery is a perfect example of how we are still evolving because people born more recently have a higher prevalence of this artery when compared to humans from previous generations." The research was carried out by tracking the rate of retainment of different parts of the body through the generations and dissecting preserved corpses of people born throughout the 20th century. https://news.sky.com/story/...xtra-artery-12099689 MidEngineManiac OCT 09, 09:43 PM Looking around me, seems a lot were born without brain tissue starting about 30 years ago too.

Broken jaw getting them out at 23 was not a pleasant experience !!!!! htexans1 OCT 12, 04:24 PM Humans that travel to other planets and staying there, like Mars (or farther away) will evolve too. Its bound to happen. Jake_Dragon OCT 12, 04:44 PM Both myself and my sister never got wisdom teeth. As far as I know we are the only ones in the family. sourmash OCT 12, 09:40 PM quote Originally posted by MidEngineManiac: Lucky bastage.

I was scared chitless of what I was going to do when it was my turn having watched my brother and sister with impacted ones. blackrams OCT 13, 07:22 AM quote Originally posted by htexans1: Humans that travel to other planets and staying there, like Mars (or farther away) will evolve too. Its bound to happen. Agreed, all living things will evolve with time and as their environment changes. One notable example is of the astronaut twin brothers where the one in space for a year came back with changes in his DNA. Prior to his year in space, the identical twins had identical DNA but now don't. Change and time drive what we are. I used to be a die-hard Democrat, now not so much. See how that happens. Rams olejoedad OCT 13, 09:18 AM I've noticed lots of people that have been evolving to the point that they don't seem to use their brains.....
