Evolution T7 PART A

This is the complete section A of evolution flashcards

QuestionAnswer
Mechanism How something works
Inherited characteristic A characteristic that parents pass to their offspring through their DNA
Acquired characteristic A characteristic that parents get during their lifetime which cannot be passed to their offspring through their DNA
Species A group of organisms that can successfully reproduce with each other
Evolution The slow inherited change of a species over many many generations
Natural selection Darwin's explanation of how evolution happens based on four ideas: overproduction, variation, adaptation, and spread of successful variations
Variation Differences in an inherited trait among members of a species
Adaptation A variation that helps an organism to survive better than an organism without the variation
Gradualism Explanation of how fast evolution happens and how new species evolve; gradualism says new species evolve slowly by gradual change
Punctuated equilibrium Explanation of how fast evolution happens and how new species evolve; punctuated equilibrium says new species evolve "quickly" due to small genetic mutations and/or rapid environmental change, then stay the same for long periods of time
