Over a century ago, scientists discarded a proposed theory that human limbs evolved from gills, given the lack of evidence in the fossil record. That theory is being revisited in light of new genetic results just published in the journal Development.

Basically some of us, were like the baddest sharks in the oceanic playground. We were dreamers, and we knew there was something more out there for us. Like strip clubs and cocaine. So we said “fuck these guys” and through sheer will and because we believed, we swam in radioactive much and mutated and became the humans we are today. Eventually, we made the lasers we always wanted. 😉
IT MIGHT look like an amputated rat forelimb, but the photo above is of something much more exciting: the limb has been grown in the lab from living cells. It may go down in history as the first step to creating real, biologically functional limbs for amputees.

Awesome, they’re leveraging the approach used to grow lungs. They’ve got issues to address, like circulation and nerves… But I count that has problems they’d probably like to have 😉
The possibility of a natural limb means no need for immuno-suppression drugs, no need for powering, no degradation of the body where the limb attaches/anchors… This is seriously good news for amputees.
