Natural Selection
What is natural selection?
This is the name of the process where individuals with beneficial traits survive and reproduce more.
What is inheritance?
This is the process by which traits are passed from parents to offspring.
What is variation?
This term refers to the differences between individuals in a population.
What is an adaptation?
A trait that helps an organism survive in its environment.
What is speciation?
This term describes the formation of a new species.
What is change or evolution?
Natural selection causes this to happen to populations over time.
What are genes?
These carry the genetic information passed from one generation to the next.
What is genetic variation?
This type of variation is caused by changes in an organism's DNA sequence.
What is a structural adaptation?
This type of adaptation involves physical features like fur color or body shape.
What is isolated?
Speciation happens when groups of organisms become this from one another.
What is survive and reproduce?
Natural selection favors individuals that can do this better in their environment.
What are chromosomes?
These structures in the cell contain the genes inherited from parents.
What is phenotypic variation?
The range of traits or characteristics seen in a population, such as size, color, or shape.
What is a behavioral adaptation?
This type of adaptation involves how an organism acts or behaves.
What is reproductive isolation?
When two populations can no longer mate and produce fertile offspring, this has occurred.
What is many generations?
Natural selection works over this span of time.
What is DNA?
This is the molecule that carries genetic instructions in all living organisms and is inherited from both parents.
What are mutations?
These are the main sources of variation that result from changes in DNA.
What is a physiological adaptation?
The ability of some animals to hibernate during winter is an example of this kind of adaptation.
What is geographic speciation?
This type of speciation happens when populations are separated by physical barriers like mountains or rivers.
