One of the courses I did during my degree was the Evolution of the Vertebrates. It was *fascinating* to see the parallels among various animal classes, especially in their embryology! Many of the now-extinct dinosaurs had much more in common with today's birds than you'd expect and the existence of a creature like Archaeopteryx (the fossil bird that shows lots of reptilian features - such as a 'beak' lined with teeth, scaly skin bearing feathers and reptile-like claws) just increases the magic.
Baby birds certainly look like little reptiles to me! I read Darwin's 'The Voyage of the Beagle' when I was eleven and remember being astounded at the way he related the forms of the Galapagos finches to their niches. Recently, I read the autobiography of Sir David Attenborough and thought to myself that all people who love nature share something very special indeed.
Be-e-e-eth! I'm not brilliant! I've just been around for a long time. Oh, and I've got a weird memory. Certain things stick with me while others (usually involving money) just waft away. LOL!
Thanks for the link! Guess what I'll be doing for the next while? (ie. Reading it)
Y'know, back when I studied all that stuff, DNA had not long been isolated. I remember sitting in lectures and being told 'one day, DNA analysis will be able to prove and disprove a lot of the relationships we can only guess at'. And lo! It did! What *really* drives me mad is that I'm beginning to forget a lot of stuff I want to remember. Urk! I used to be able to recite the evolution of the vertebrates from Amphioxus up to Homo Sapiens. Can't do that any more. Snif! (I can still spell all the complicated names, though, so that's something...)
Interesting things to think about: evolution of the air sac (did it come from lungs or instead of lungs?); evolution of the avian jaw and bill; evolution of the cleidoic ('shelled') egg and evolution of the pentadactyl (five-fingered) limb, especially with regard to birds and flight. Birds are special: they're the only Class of animals that truly conquered the skies and made it their own. In fact, it's another interesting area of study: the evolution of flight in reptiles, birds and mammals. Did you know there are 'flying' lizards and snakes, for example?
All forms of Life are amazing! Not only that, but they're all interconnected in the most wondrous and elegant ways. I've spent my whole life being mesmerised by living things (ever since I caught my first ant at the age of three) and astounded by watching them live and grow. I feel *so* lucky to have been able to do that! And especially lucky to have wound up in this forum where everybody else feels the same way about birds as I do.
Sorry to write an essay. As you've probably noticed by now, I get all worked up over these things.
