Punctuated equilibrium
Which of the following is NOT one of Gouldd’s three general arguments for evolution?
The scientific method has proven that natural selection is true
Is the central idea of intelligent design, that biological organisms could not have been produced by natural processes (like natural selection) is a testable hypothesis ?
No
Does the scientific method ensure that good theories will eventually become facts?
No
What is NOT one of Darwin’s postulates?
The perfection of nature
Natural selection operates at the level of

Translation
Every meiosis, bits of the chromosome you got from your mother exchange with bits you got from your father. This is known as:
Recombination
If an individual who is heterozygous for the sickle cell allele (Aa) mates with an individual who is homozygous for the normal allele (AA), what is the chase that their offspring will have sickle cell anemia (aa)
0%
The nuclei of most human body cells (other than gametes) have
23 pairs of chromosomes
What are the 4 DNA bases?
A, C, T, G
Each gamete is genetically unique because of which of the following processes
Independent assortment
Suppose that a population of lizards disperses to an island. This island has a few large predators that eat the smallest lizards. It also has less food than were the lizards come from, and the largest lizards can’t get enough to eat to survive. Over time, there are fewer very large and very small lizards in the population. What TYPE of natural selection is acting on the lizard population?
Stabilizing selection
Sometimes when a large number of new ecological niches become available, many new species form quickly. This process is known as
Adaptive radiation
Migration (gene flow) ____ genetic differences between populations
Decreases

DNA - mRNA - tRNA - amino acid - polypeptide
The _______ reconciled Darwin’s hypothesis of gradual evolution with Mendel’s laws of inheritance
modern synthesis
