Travels of a Fish Nut

This is another long post with a lot of complicated words. I'm sorry about that, but this will hopefully be the last post like this for a while. In the next one we'll start looking at the different types of animals.  What is natural selection? Here’s an experiment for you to try. It will take both of you and your mum to watch and time you (and maybe help with the maths).

Evolution is a simple concept when explained well (which I hope I will be able to do!) but in order to fully understand it I need to explain a few things about cell biology. I will make this as brief and simple as possible because it’s not our focus at the moment (though if I am able to keep up these posts it will be at a later date) but it involves some complicated words and ideas which I can't really avoid so apologies in advance.
