Humans bones became lighter and frailer once farming became widespread
Our bones are much lighter and weaker than those of our Paleolithic ancestors (11,000 to 33,000 years ago), but it’s not our spoiled modern day lifestyle that’s to blame. Instead, a new study which closely compared homo sapiens bones, both ancient and modern, found that the most significant changes occurred once the paradigm shift from hunter-gatherer to agriculture took place, some 10,000 years ago. Humans started forming permanent settlements, worked the land and tended to flocks. Consequently, the lifestyle became more sedentary.
This pen 3-D prints bone directly on site of injury
Medicine and 3-d printing fit together like a glove. Imagine how many transplants and surgical procedures are so difficult to make or downright impossible because you can’t find a matching tissue or body part for the patient at hand. With 3-D printers, you can even make new bones – identical to those modeled from a patient that would require them.
