HTTP:: Evolution Only Goes One Way
--------
Evolution in a biological context roughly translates into a species' ability to favor the passing on of genes that ensure its survival into the next generation. In order for this to happen, mutations must occur. Mutations generate diversity, but can also have adverse effects on a species, and lead to its extinction. In a groundbreaking, new study, experts discovered that, once a protein, for instance, evolved into a higher form than its original one, it could no longer devolve, or go back to its previous state. The experts behind the investigation say that there is no easy way of going back, LiveScience reports. As various species of humans evolved from the common ancestors we share with primates, it was mutations and adaptations that set our ancestors on a path to becoming the dominant species on the planet. If evolutionary regression had been possible, then at least some humans would have surely devolved back into forms similar to the common ancestor, once the environme!
ntal factors that drove their mutations in the first place disappeared. However, historical records and fossil discoveries show that this type of events never took place. “Evolutionary biologists have long been fascinated by whether evolution can go backwards. But the issue has remained unresolved, because we seldom know exactly what features our ...
