Document Summary

1. 7m described species and for each species, 100 have already gone extint. Biological diversity = interactions between preceded forms and is an ongoing process.

How to study evolution: 1) population and quantitative genetics (change in allele frequencies real-time), 2) paleobiology (large-scale evolutionary changes), 3) integration of genetics & morphology (developmental patterns and evolutionary transitions) Tried to tell the scientific community that species can evolve and/or go extinct, instead of the common thought that they move away. Lyell (1797-1875) said that landforms slowly changed + earth was much older than assumed. Lamarck (1744-1829) inspired the thought of inheritance in darwin. Believed that species changed over time (transmutation) + acquired traits can be inherited, lost through disuse. Faster than food = competition & survival of the fittest. Darwin: finches varied from island to island, but closer islands had more similar finches.
