Risen Apes And Fallen Angels: The New Museology Of Human Origins, Stephen Asma
Risen Apes And Fallen Angels: The New Museology Of Human Origins, Stephen Asma
Stephen T Asma
There has been a little explosion of "origin" exhibitions in the past few years. The recent bicentennial of Darwin's birth, in 2009, ushered in a bevy of traveling exhibitions and events. Grandscale permanent exhibitions have recently opened at the American Museum of Natural History (the Spitzer Hall of Human Origins) in New York, and the Smithsonian's National Museum of Natural History (the David H. Koch Hall of Human Origins) in Washington, D.C. A new museology is afoot, and some of the recent changes are worth tracking. And let's not forget the recently opened Creation Museum in Petersburg, Kentucky. Even in …

Levels Of Biological Organization And The Origin Of Novelty, Brian Hall, Ryan Kerney

The concept of novelty in evolutionary biology pertains to multiple tiers of biological organization from behavioral and morphological changes to changes at the molecular level. Identifying novel features requires assessments of similarity (homology and homoplasy) of relationships (phylogenetic history) and of shared developmental and genetic pathways or networks. After a brief discussion of how novelty is used in recent literature, we discuss whether the evolutionary approach to homology and homoplasy initially formulated by Lankester in the 19th century informs our understanding of novelty today. We then discuss six examples of morphological features described in the recent literature as novelties, and …
