Well, that’s revealing, isn’t it? The evolutionary biologist admits that epigenetics is controversial, not because it can’t be demonstrated (it can) but because it provides competition for “traditional Darwinian inheritance.” Read More ›

Beetle larvae (“superworms”) can survive on waste plastic

Recent evolution? Maybe. Doesn’t sound as though much evolution is needed, actually. Later in the article, it is suggested that the required enzymes may have existed for some time (that is, the plastic is what’s new). Read More ›

Are synthetic chemicals altering the fabric of our bodies?

It’s certainly worth reflecting on: It’s fair to say that PCBs and fluorocarbons have altered the biochemical composition of the food web and the interior of the human body, and in the case of the PFASs, the water we drink. (Some PFASs can even fall with rain.) These have been swift, sweeping changes over the course of just three or four generations, too quick for the slow-grinding machinery of human evolution to adapt. And yet, PCBs and PFASs are now an integral part of the human story. They pass from species to species, from mother to child. They are present from conception to death, and consumed with daily meals and holy feasts. The presence of PCBs alone shapes how humankind Read More ›
