Not at all medican'. But this is a serious subject for me, although I expect a certain amount of derision from some quarters that's fine because it gives me an excuse to talk about it.
living within the evolutionary cycle there are billions of species on this planet. That's just the ones you can see. There is also an invisible world full of species you can't. Each of these species is evolving at a rate that is determined on the species' need to survive in their given environment.
Do a search on the Galapagos Islands and cross section that with Darwin for a fuller explanation of the discoveries there. The Islands are ideal for research on evolution because the islands have the same animals on each. The Islands climates are all extremely different despite their proximity to each other and the same animals have different characteristics on different islands. Which shows evolution because (forgive me if you have difficulty understanding, I'm quite mashed now) the... o.k. lets start again. Let's take 2 of the islands and the turtle that inhabits both. At one time the turtles started out the same but as the Islands are isolated from each other over time the turtles were split between the two islands. On the 1 island the available food is in abundance and the turtle quite happily has enough to survive so evolution for the turtle on this Island is slowed. Now take island number two and the same species of turtle (the exact name is lost to me now), the conditions here are far worse and the only available food source available to the turtle is one it has to stretch up it's neck to reach. Over years these turtles' (check this out if you like, it'll make good reading) shells developed a dent just above their head so they could stretch up further to reach the available food. It would have started as a small dent but over years those turtles can reach more and more food as the dent got bigger. If you want me to explain more I will, only not now.
