The Elements of Biodiversity - Biological Diversity
The measurement of biodiversity is complex and has a qualitative as well as a quantitative aspect. If a species is genetically unique — if, for instance, it's far out on a remote arm of the evolutionary tree, like the distinctive, peculiar platypus — its biodiversity value is greater than that of a species clustered with many similar species because it preserves a unique part of the ...
About the Center - Biological Diversity
At the Center for Biological Diversity, we believe that the welfare of human beings is deeply linked to nature — to the existence in our world of a vast diversity of wild animals and plants.

Mammals - Biological Diversity
Mammals are warm-blooded vertebrates with sweat glands, hair, three middle ear bones and a neocortex region in the brain. Their gradual evolution from mammal-like “reptiles” called “synapsids” spanned about 70 million years. The first clear evidence of fully mammalian jaw joints and middle ears was found about 200 million years ago; mid ...
Plants - Biological Diversity
Plants are a kingdom of life forms that includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns and mosses. Through photosynthesis, they convert water and carbon dioxide into the oxygen we breathe and the sugars that provide the primary fuel for life. Through nitrogen fixation, plants generate proteins that are basic ...
