Bees and flowers are an example of this.

When an organism builds resistance to something over time.
What is tolerance.

This man contributed to ecology by studying species on the Galapagos Islands and proposed the Theory of Evolution.
Who is Charles Darwin
200
This is increased through mutations and gene shuffling.
What is genetic variation
200
This is what is believed to have occurred to wipe out all the dinosaurs.
What is mass extinction
200
This is an increase in variabillity through mutations in gene shuffling.
What is genetic mutation.
200
These are the evidence that scientists use to prove that there was life long ago.
What are fossils
300
This is a tool of survival is used when a snow fox blends in with the surrounding snow.
What is camouflage
300
Name and define ways in which natural selection can affect populations.
What are stabilizing selection-more fitness in middle of graph, directional selection-more fitness in the end of the graph, and disruptive selection-more fitness at both ends of the graph; middle graph dies.
300
A long period of no change followed by a sudden rapid change is due to.
What is punctuated equilibrium
300
This is the process that leads to the formation of a new species.
What is speciation
300
Not to be confused with its counterpart, these structures have similar function, but different structure.
What are analogous structures.
400
This is the study of similarities of organisms during development.
What is embryology
400
This causes allele frequencies to stay the same generation to generation.
What is genetic equilibrium.
400
Male fireflies of a variety of species signal to their female counterparts by flashing their lights in specific patterns. Females will only respond to the signals flashed by their own species, preventing them from mating with other closely related firefly species. This is an example of
What is behavioral isolation.
400
Also known as mutualism, this is when 2 species evolve in response to change in each other.
What is coevolution.
400
Lichen is an example of this.
What is a pioneer species.

"Black on yellow, kill a fellow. Red on black, won't hurt Jack." This rhyme describes this tool of survival.
What is mimicry
500
These are the two equations of the Hardy-Weinberg Principle
What are p² + 2pq + q² = 1, p + q =1
500
Organisms that change at a slow pace or/and constant pace.
What is gradualism.
500
This was the idea that a trait changed over an organism's lifetime could be passed onto its offspring and was later proven NOT TRUE.
What is inheritance of acquired traits.
500

What is relative allele frequency.
