In a landmark decision more than two decades in the making, the US Food and Drug Administration announced its approval of a genetically modified Atlantic Salmon variant on Thursday. The AquAdvantage salmon, which was initially developed back in 1989 and submitted for approval in 1995, grows far faster than its conventionally bred brethren. The FDA has deemed it safe for human consumption, equally nutritious as other salmon varieties and not dangerous to the environment. And since the GMO salmon is considered nutritionally equivalent to regular salmon supermarkets will be able to carry the fish without having to label them being GMO.

What Is the Molecular Clock, Exactly?

In the 150 years since Charles Darwin recognised the kinship of all life, scientists have worked to fulfil his dream of a complete Tree of Life. Today, the methods used to trace the evolutionary branches back through time would exceed Darwin’s expectations. Scientists across a range of biological disciplines use a technique called the molecular clock, where the past is deciphered by reading the stories written in the genes of living organisms.
