Not all offspring can survive. Chapter 5 Evolution of Biodiversity Objectives Quantify biodiversity. Explain how evolution can occur through natural selection.

Adaptation Any genetically controlled structural physiological or behavioral characteristic that helps an organism survive and reproduce under a given set of environmental conditions. The variety of species in a given ecosystem. In contrast to some previous mass extinctions there is agreement among scientists that the current mass extinction has human causes.

A fossil of higher. Differences in traits are associated with differences in the ability to survive and reproduce. Evolution of Biodiversity Summary This chapter explains evolution and the processes that have created biodiversity on our planet.

If there is sufficient biodiversity when an environmental change occurs some variations may be adapted to the changing environment.
