Evolution
Molecule that all living things have in common.
What is DNA?
Occurs when organisms with favorable variations survive, reproduce, and pass on their variations to the next generation.
What is natural selection?
variation
What is biodiversity?
A change in inherited traits over time.
What is Evolution?
This type of evidence involves comparing organisms' genetic code.
What is DNA evidence?
More offspring than necessary are produced in hopes that some will survive.
What is overproduction?
homologous pairs exchange similar section of the chromosome in prophase I
What is crossing over
the end of a species
What is Extinction?
Evolution in which organisms split from a common ancestor.
What is divergent?
This type of structure shows similar ancestry, but different functions.
What is homologous?
The change of living things over time.
What is Evolution?
when the average individual in the population have higher fitness and are favored
What is stabilizing selection
a branching diagram showing the inferred evolutionary relationships among species
What is Evolutionary Tree
Diversity; or different inherited traits in the same type of organism (2 words)
What is Genetic variation?
This type of structure shows different ancestry, but similar function.
What is analogous?
This trait can produce many phenotypes.
What is polygenic trait?
When individuals at one end of the curve have higher fitness and are favored more than individuals in the middle or at the other end.
What is directional selection?
the movement of alleles into and out of a gene pool
What is gene flow
Model of evolution that occurs in "short bursts" over time.
What is Punctuated equilibrium?
This term is given to structures that no longer serve an important function in an organism.
What is vestigial?
Darwin's hypothesis about how life changes over time is now called.
What is the theory of evolution?
new genetic combination
What is crossing over
collection of mechanisms, behaviors, and physiological processes that prevents cross-breeding
What is Reproductive Isolation?
Model of evolution where it occurs steadily over time
What is Gradualism?
This type of evidence involves studying organisms during their development.
What is embryology?
