natural selection Flashcards
(8 cards)
What is Natural Selection?
How organism’s traits allow them to survive and reproduce overtime.
What are Homologous structures ?
similar features in different species that inherit from a common ancestor.
What is Adaptation?
traits that increase a organism’s ability to survive and reproduce
without genetic variation evolutionary change like natural selection can not operate.
overproduction is when there’s too much of something than is needed or producing to much
examples of natural selection:
finches with larger beaks were able to crack open seeds causing the short beak finches to die and have large beaks become more common
evolution?
change over time
Example of evolution:
there will be light and dark frogs. predators will be hunt down light frogs as they are easier to see compared to dark frogs. overtime there will be more dark frogs.
