Continuing my adventures in la-la land, this week I thought I’d have a look at this gem from @Starchasr

This is from an Old-Earth Creationist, so he accepts that the earth is very old but denies that any evolution has taken place. That’s why he’s made the claim. Apparently animals have remained unchanged.

Sadly, anyone with a decent knowledge of biology (which by definition, means someone who is not a creationist) knows that some rather dramatic changes have occurred. If we look at one of my favourite groups, the Arachnids, then all sorts of changes have taken place.

From common ancestors likely resembling scorpions, evolution has generated a number of fairly dramatic changes.

This has features such as claw-like pedipalps and segmented opithosoma (the second body segment).

If we look at a spider, then we can see how it’s kind of nothing like that:

The opithosomal segments have fused, a distinct waist has formed, the pedipalps are leg-like, and its evolved the ability to make silk.

And neither look much like this arachnid, a native harvestman

Here the opithisoma is still segmented, the waist has gone, the pedipalps are leg-like not pincer like, and the chelicerae are nothing like the above. This guy doesn’t have venom, nor can he spin silk.
