Divergence and constraint in the origin of new species The origin of
... The origin of new species creates biological diversity and understanding species formation is thus a key goal in biology. In this talk, I will tackle the issue of why some populations that begin the speciation process diverge further than others, a phenomenon central to understanding diversification ...

... b. endangered - too few individuals, extinction soon Species need 10,000 organisms to maintain evolutionary potential. c. extinct - means gone forever - when numbers drop below 1,000 for animal species and 120 species for plants, the species is considered extinct because of the problems finding mate ...
