On my toes
September 16th, 2009 by Lisa
OK, I need some help from somebody who knows. I thought my grasp of science was quite firm but I find it shaken to its foundations by tricky questions from Maggie (who, incidentally has been in and out and in and out of school like a tee-to-tum* this past week; we have no idea what is going on except she’s a bit poorly. Sometimes.) We’ve been touching on evolution a little since our visit to the Natural History Museum in the summer, but it is all a bit confused. What can I say, ask me about molecules!
She declares she doesn’t believe in dinosaurs because it doesn’t seem very likely, does it. Well no it doesn’t – and how to explain that they are not like fairies or, you know, dragons, or something that you can choose to believe in a bit if you like but really we all know they are not true. Or Santa – and we’ve had some interesting chats about the juxtaposition of him and Jesus, also, thanks to the church school she is attending. The Christmas when Jesus was born was indeed the first Christmas, after a fashion, but was it the first time Santa brought presents? And if not, why not?
So. We established rather reluctantly that dinosaurs had existed a long time ago (we saw the skeletons, remember). But – here’s the science bit – did the monkey things** evolve from the dinosaurs? Or did they evolve from the other mammally things that were around at the same time (I think), mammoths and, um, sabre-toothed tigers and suchlike? And if that is the case, did they share a common ancestor? I am pretty firm on birds (and I imagine reptiles) evolving from dinosaurs, but didn’t some fishy thing crawl out of the swamp on its fins at some point? Was the pre-dinosaur, and did that then evolve into us or into birds?
*A thing that goes in and out a lot. No idea; ask my mum.
**She’s fairly unquestioningly happy about us having evolved from monkey things, and I am reasonably happy about hominids and Lucy and missing links. I think. We haven’t got into that in depth yet.
