Vocab Flashcards
Natural selection
Process in nature that results in the most for organisms producing offspring
Evolution
Process where modern organisms have descended from ancient organisms
Fossil
Preserved remains or evidence of an ancient organism
Artificial selection
Human control of those organisms with desirable traits to produce offspring
Speciation
New species evolving from old ones
Reproductive isolation
Deprecation of populations so that they don’t interbreed to produce fertile offspring
Adaptive radiation
One species gives rise to many species
Divergent evolution
Same as adaptive radiation
Convergent evolution
Adaptive radiation among different organisms producing species that are similar with appearance and behavior
Homologous structure
Develops From same body parts but meet different needs
Analogous structure
Structures that are similar in appearance and function but have different origins
Radioactive dating
Using radioactive elements to determine age of fossils
Radioactive decay
Half life of radioactive elements
Common descent
Species descended from common ancestors
Vestigual organ
Reduced in size or function
