Evolution Vocabulary

Vocab words needed to know for the Evolution Unit.

Evolution The process through which species develop new traits.
Species A group of similar organisms that reproduce among themselves.
Overproduction When a plant or an animal reproduces, it usually makes more offspring than can possibly survive.
Variation Is essential for new species to evolve. Differences among individuals result from differences in the genetic material.
Natural Selection The process by which forms of life having traits that better enable them to adapt to specific environmental pressures will tend to survive and reproduce in greater numbers than others of their kind.
Adaptation Any inherited trait that gives an organism a better chance to survive in its particular environment.
Mutation Change in genetic material which causes a new variation.
Selective Breeding Selective breeding is the process by which humans breed other animals and plants for particular traits.
Artificial Breeding The process by which humans breed other animals and plants for particular traits.
Charles Darwin Believed that species evolve through natural selection.
Isolation Separation of populations by geographical or other barriers and prevents reproduction. Contributes to the process of speciation.
Jean Baptiste de Lamark Suggested that when giraffes stretched their necks to eat from tall trees, their offspring inherited this longer neck.
Observation The action or process of observing something or someone carefully or in order to gain information.
Speciation Evolution of new species from an existing species.
Artificial Selection The process by which humans breed other animals and plants for particular traits.
Fossil Evidence Fossils provide evidence that two species with a common ancestor can develop differently in different locations.
Biological Evidence Includes looking at the structure and development of living things.
Genetic Evidence Scientists can tell how closely organisms are related by comparing their DNA.
Vestigial Organs Physical structures that existed in an earlier group of organisms but are reduced and unused in later species.
Homologous Structure Features of 2 organisms that have similar structure, but have different functions. EX: human arm and bird’s wing (common ancestor).
Analogous Structure Features of 2 different species that are similar in function, but differ in structure. EX: wings on butterflies and wings on bats (no common ancestor).
Embryonic Development Organisms resemble each other in early stages of development, but look less and less alike as they grow.
Classification The process of arranging organisms into groups based on similarities.
Ancestor Early form of an organism from which later forms descend
