The evolution of wings in birds and wings in insects is an example of
What is Convergent Evolution?
Given that the recessive allele is present in a population at .9 frequency, what is the frequency of the dominant allele in the population?
What is .1?
Organisms change over time. For example, if that horse keeps practicing jumping over the fence, it will eventually grow longer legs and pass those down to its offspring.
Who is Jean Baptiste Lamarck?
the number of different types of species living in an area is referred to as...
What is species richness?
Female mormon crickets select their mates based on who has the biggest sperm packet. This is an example of which evolutionary mechanism?
What is Sexual Selection?
As a young biologist, Charles Darwin had expected the living plants of temperate South America would resemble those of temperate Europe, but he was surprised to find that they more closely resembled the plants of tropical South America. The biological explanation for this observation is most properly associated with which line of evidence for evolution?
What is Biogeographical evidence?
A population of sheep is in Hardy-Weinberg equilibrium. The allele for white wool (A) has an allele frequency of 0.19, and the allele for black wool (a) has an allele frequency of 0.81.
What is the percentage of heterozygous individuals in the population?
What is .307 or .31?
Individuals are better adapted to their environments so that they can survive and reproduce, and thus pass on their genes.
Who is Charles Darwin?
The proposed geological age, viewed as the period during which human activity has been the dominant influence on climate and the environment.
What is Anthropocene?
A population of squirrels exists with variation in tail length. A new predator moves into their territory. Short squirrel tails help them evade the predator while long tails are good for balancing in trees. Medium tails are useless. Eventually medium tailed squirrels are eaten. This is an example of what kind of natural selection? Draw a simple graph to show your answer too!
What is disruptive selection?
The criteria used to determine anatomical homology
What is composition, positioning, and development?
If a population has the following genotype frequencies, AA = 0.25, Aa= 0.50, and aa= 0.25 what are the allele frequencies?
What is p = .5 and q = .5?
The Earth is much older than people think it is.
Who is Hutton and/or Lyell?
The level of biodiversity that involves the variety of living organisms in an area
What is species level of biodiversity?
Natural selection is random, mutations are not. Is this a true or false statement?
False.
Burrows, footprints, and feces are all examples of what?
Trace fossils
A population is in Hardy Weinberg Equilibrium if these five conditions are met.
Large population
Random mating - no sexual selection.
Everyone is equally fit - no natural selection
No gene flow in or out of the population
No mutations
Totally against evolution, but solidified the concept of extinctions occuring due to catastrophes.
Who is George Cuvier?
The rise and fall of biodiversity reflect differences in these two processes
What is speciation and extinction?
Natural selection acts on individuals and populations evolve. Is this a TRUE or False Statement? Explain your choice.
What is TRUE?
Evolution of olfaction (sense of smell) in animals, such as humans and mice, was likely due to:
What is multiple gene duplications?
The ability to taste phenylthiocarbamide (PTC) is a trait controlled by 2 alleles (PTC taster and PTC non-taster). Suppose 36% of a remote mountain village cannot taste PTC and must, therefore, be homozygous recessive (tt) for the PTC non-taster allele. If this population conforms to Hardy-Weinberg expectations for this gene, what percentage of the population must be homozygous (TT) for the PTC taster allele?
What is .16 or 16%?
If you do not know the names of things, then the knowledge of them is lost, too. Also, I don't believe in evolution.
Who is Carolus Linnaeus?
