Evo-Devo & Lucy

The continuous unfolding of the fossilized skeleton, Lucy, is illustrious of how historical anthropological evidence can serve to better understand evolutionary development. Although Lucy's remains were found over 20 years ago, research and published articles still make their way into the public eye. "Meet the ancestors: the story of our evolution continues" is another example of this phenomenon, and Lucy is to thank. As I mentioned in class, I believe I saw the skeleton at the World's Fair in Germany, 2000. It was remarkable to examine (through thick, plate glass) the fossils, reaching only 3' 8, but 3.2 million years old. The remains were so small, and yet it was reminiscent of something- ah yes, the human skeleton (see below). Scientists have continued to uncover more fossils and piece together (literally) how we have evolved to Homo sapiens, examining pelvic structures, foot bones, brain size, in addition to atmospheric change and how climate had an impact on existing species. I believe it is a gift to have evidence of the evolutionary process; it is difficult to be skeptical when there exists tangible, visible structures which illustrate development of species. I am appreciative of these learning devices and look forward to more discoveries, which will further enhance our understanding of evo-devo and how perhaps, as Homo sapiens, we can avoid catastrophe and extinction...
