EVOLUTION AND GTS VOCABULARY

Species – Group of organisms that can mate with each other to produce fertile offspring

2**Generation Time – Period between birth of one generation and birth of the next generation

3Pangaea – Single landmass surrounded by gigantic ocean; means “all Earth”

4 Struggle to Survive – Part of natural selection theory: individuals within a population compete with each other for limited resources

5Mesozoic Era – Period from 248 mya-65 mya; called “age of reptiles

6**Fossil Record – Historical sequence of life indicated by fossils found in layers of Earth’s crust

7Extinct – Describes a species that has died out completely

8Evolution – Process by which populations’ inherited characteristics change over time

9Absolute Dating – Method of measuring the age of fossils or rocks in years

1Inherited Variation – Part of natural selection theory; individuals within a population have slightly different traits

1Relative Dating – Estimating the age of rocks and fossils

1Darwin – Naturalist who is considered the “father of evolution” and wrote the theory of natural selection

1 Neanderthal – Hominid that hunted large animals, made fire, and wore clothing

1Plate Tectonics – Theory that explains how large pieces of Earth’s crust move and change shape

1Paleozoic Era – Period from 543 mya-248 mya; means “ancient life”

1Fossil – Remains or imprint of a once living organism

1Cenozoic Era – Period from 65 mya-present day; called “age of mammals”

  Precambrian Time – Period from 4.6 mya-543 mya; no oxygen, volcanic eruptions, intense sun radiation

1Adaptation – Characteristic that helps an organism survive and reproduce in its environment

2Hominid- Type of primate that includes only humans and their human-like ancestors

2Speciation – Formation of a new species as a result of evolution (separation, adaptation, division)

2 Natural Selection – Process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals; theory to explain evolution

2 Homo sapiens – Species of hominids that included modern humans and their closest ancestors

2 Overproduction – Part of natural selection theory; each species produces more offspring than will survive to reproduce

2 GTS (Geologic Time Scale) – Standard method used to divide Earth’s long natural history into manageable parts

2  Successful Reproduction – Part of natural selection theory; individuals that are better equipped to live in an environment are more likely to survive to reproduce
