keywords: abiogenesis, cell biology, evolutionary biology

In this second foray into the biology of death, I will examine programmed cell death or PCD. You might have heard of the process of apoptosis, but, as the previously reviewed The Biology of Death mentioned, this is just one of many ways in which cells can actively kill themselves. It is a vital part of life in multicellular organisms, for instance sculpting our hands so that we are not born with webs of skin between our fingers, or allowing leaves to fall from the trees in autumn by triggering cell death in so-called abscission zones. These are small sacrifices to serve the larger organism. Surprisingly, single-celled (unicellular) organisms also show PCD. But wait, is that not tantamount to suicide? How did that evolve?

Book review – Through a Glass Brightly: Using Science to See Our Species as We Really Are

6-minute read

Science has brought us many advances and has deepened our understanding of the world around us, pushing back the boundaries of our ignorance. But as it has given, so it has taken. It has revealed a vast stage whose age is measured in incomprehensible epochs of Deep Time and whose dimensions stretch away into the frigid depths of an uncaring cosmos. Leaving us bereft of meaning and purpose, science has driven home how utterly insignificant we, the denizens of that Pale Blue Dot, ultimately are. Personally, I find this perspective deeply humbling and I know many scientists feel likewise, but I also realise we live in a bubble of our own.

The notion that we are unique, special, or – in the eyes of many still – God’s chosen children, persists. Luckily for us all, evolutionary biologist David P. Barash is here to take down our “species-wide narcissism” a peg or two (or three). But far from a self-congratulatory circle-jerk, Through a Glass Brightly is an erudite, life-affirming, and sometimes riotously amusing look at ourselves.

Book review – Genesis: On the Deep Origin of Societies

Why, of all the species that have ever existed, have only us humans reached this unparalleled level of intelligence and social organisation? When a senior scientist such as Edward O. Wilson trains his mind on such a question, you hope to be in for a treat.
