Describe Natural Selection
Individuals within a population exhibit differences in their traits is called________________?
Variation
Different structures. Same function
Analogous structures
A bat wing, whale flipper, and a human arm are what type of structures?
Homologous
A distinguishing quality or characteristic that makes an organism unique or able to survive and reproduce.
Trait
This is the code that form genes found in every living organism
DNA
Individuals with certain traits have a greater chance of surviving and reproducing compared to others is differential _____________ success.
Reproductive
Structures at one time DID have a function, but not anymore.
Vestigial Structures
The human appendix is which type of structure?
Vestigial
The adjustment or change in behavior or structure within an organism that makes it suitable to survive in its environment.
Adaptation
Darwin sailed this ship to collect his evidence on his theory of natural selection
HMS Beagle
Resources within an environment are limited, leading to competition among individuals for survival and reproduction is the ____________for existence.
Struggle
Similar structure but different function
Homologous structures
A bat wing, a bird wing, and a butterfly wing are what type of structures?
Analogous structures
The study of the geographical distribution of living things that can lead a species to evolve in multiple species.
Biogeography
This environmental factor changed the reproductive success of moths from light to dark.
Soot from the industrial revolution
Natural selection is defined as?
Organisms that are more adapted to their environment are more likely to survive and pass on the genes.
The age of the fossils can be determined by the age of?
Rocks
Wisdom teeth, or a third set of molars found in the rear of the human jawbone that provided the greatest chewing power.
Vestigial structure
A change in DNA can happen spontaneously or through environmental factors such as radiation and chemicals within the environment.
Mutation
The type of selection that allows human to selectively breed animals/vegetables for desired traits
Artificial selection
Evolution is simply defined as?
Change over time
The evidence that shows similarities in the early development of an organism
Embryonic development
The eyes of octopuses and humans
Analogous structures.
The type of diversity that accounts for all living organisms on Earth, unfortunately decreasing each passing year, and thus promoting biodiversity loss.
Species diversity
Recalling the three types of selection curves, this type allows both traits to be present as dominant
Disruptive selection
