Subject Area:

life science


Standard:

Understands the basic concepts of the evolution of species.


Benchmarks:

Knows that the basic idea of evolution is that the Earth's present-day life forms have evolved from earlier, distinctly different species as a consequence of the interactions of:

- The potential for a species to increase its numbers

- The genetic variability of offspring due to mutation and recombination of genes

- A finite supply of resources required for life

- The ensuing selection by the environment of those offspring better able to survive and leave offspring

Knows that natural selection leads to organisms that are well suited for survival in particular environments, so that when an environment changes, some inherited characteristics become more or less advantageous or neutral, and chance alone can result in characteristics having no survival or reproductive value.

Knows how natural selection and its evolutionary consequences provide a scientific explanation for the diversity and unity of past and present life forms on Earth (e.g., recurring patterns of relationship exist throughout the fossil record; molecular similarities exist among the diverse species of living organisms; the millions of different species living today appear to be related by descent from common ancestors).
