Document Summary
Biological evolution is the change of populations/organisms over time: measured in generations, not years (e. g. blowfly evolved over many 11 day. Changes that occur over the lifetime of a single organism are not evolutionary (i. e. aging) Careful examination of similarities and differences of biological species enabled aristotle to create a ladder-like classification of nature from the simplest to the most complex called the. Biological research was dominated by natural theology which sought to name and catalogue all of god"s creation. By 1600 sir francis bacon established the importance of observation, experimentation and finding evidence to support a theory/proposal (inductive reasoning) The collective work of many scientists gave rise to three new disciplines biogeography, comparative morphology and geology. Global exploration provided naturalists with many unknown species. Figure 17. 1 these three species of large, flightless birds, with greatly reduced wings appear very similar. The african ostrich, the australian emu and the south american rhea occupy similar habitats in geographically separated regions.
