Define Evolution | the process through which a populations traits change over time |
Differentiate between microevolution and macroevolution | Evolution or change on a small scale, Evolution or change on a large scale |
Define a species | organisms that are so genetically similar that they have the potential to breed and produce organisms that are living and able to reproduce eventually themselves |
List the 4 criteria's that define a population | same species of organisms,located in the same location,at the same time,showing signs of reproduction |
What is a geographic barrier?Example | a large mountain large bodies of water. Atlantic Ocean or Mt.Everest |
What is a mutation? How could it lead to evolution? | random changes that occur in organisms DNA.It can lead to evolution as long as the population can grow and reproduce |
Define Natural Selection? | survival of the fittest |
Define overproduction.Give an example. | is a species ability to produce more off spring than the environment can support. Bunnies reproduce on a land that can only support 50 bunnies but there are 80 bunnies |
Define competition.Give an example | is an interaction between organisms or species in which both the organisms or species are harmed.If 50 bunnies keep reproducing and the land their on can only hold 80 and wolves come and kill all of them except for 50. |
Differentiate between natural selection and artificial selection.Give an example. | Natural Selection is random Artificial Selection is man made |
What is ERA? | largest period of time |
Different between homologous structures and analogous structures | homologous indicates common ancestry and analogous does not |
Define embryological homologies | common stages of development that occur in embryos |
Define molecular homologies | DNA nucleotide sequences being exact in order and function |
