|
theory |
well-substantiaed explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses. |
|
|
hypothesis |

|
Evolution |
the theory of evolution is a unifying principle for understanding the history of life on earth, relationships among living things, and dependence of life on the physical environment. Best explanation that we have for the diversity of life on Earth. DECENT WITH MODIFICATION. |
|
|
Decent with modification |
all living species are the modified descendants of earlier species, and that all life shares a common ancestor in the distant past. |
|
|
Heritable change |
genes that can be passed down |
|
|
microevolution |
evolution viewed by the change in gene frequencies. |

|
macroevolution |
the formation of a new species |
|
|
natural selection |
mechanism for evolution, adaptive, population of organisms evolve in such a way as to become better suited to their environments as advantageous traits become predominant over time. |

|
mutation |
random change in the DNA sequence. |
|
|

|
|
adaptation |
the process by which populations evolve in such a way as to become better suited to their environments as advantageous traits increase in frequency |
