If you’re near Bristol: to commemorate Darwin, Bristol Zoo is offering free entry to anyone who turns up this morning with a beard (real or fake). As I write, there’s about 2 1/2 hours left to claim, so you’ll have to rush.

As it happens, only the other day I was reading a book which reminded me how important it is to remember Mr Darwin, as important as it ever was. Counterknowledge, by Damien Thompson, a short book on a long long subject: how falsehoods such as creationism and pseudoarchaeology are presented as somehow equal to facts and truth. How they are presented by the media as a “debate”, when one side’s evidence greatly outweighs the other.* It’s easy to find people today who believe that evolution is wrong; that somehow, because they find life beautiful, there must be a purpose and a designer behind it. And from there it’s a slippery slope to believing first that species are immutable; and from there, that conservation is unimportant, that God must have given us everything we need, and that Genesis 1:28** gives humanity the right to use up any and all resources that there are.

* as much as the inactive contents of a homeopathic remedy outweigh the active contents, you could say.

** “God said unto [man and woman],*** be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.”

*** Not “Adam and Eve”, note. Adam and Eve aren’t in the “six days” story of Creation, which this verse is part of. They’re in the second Creation story, which starts at Genesis 2:4; where God creates Adam from the barren earth and then Eden for him to live in.
