True Or False Flashcards
The organisms that are alive today are best suited to their environments
True
Alfred Russel Wallace was the first to propose that life can change over time through his theory of acquired characteristics.
False
Comparing embryos of different animals and seeing their similar developmental sequences provides evidence for evolution from a common ancestor.
True
An example of artificial selection is when the allele for long necks in giraffes was selected for because it allowed giraffes to reach leaves in the tree tips and thus have energy to survive and reproduce.
False
Gene flow occurs when individuals migrate into or out of a population.
True
Vestigial structures are body parts that no longer have a major function in animals today.
True
Founder effect occurs when individuals leave the general population and start a new population thus the allele frequencies in the new population is different compared to the original population.
True
Micro evolution occurs over a very long period of time whereas macro evolution occurs over a short period of time.
False
The gene pool represents only the genes if those individuals that were born into the population and not those that migrated into the population
False
Bottleneck effect occurs when there is a random change in allele frequencies of a population due to things like natural disasters, disease, predation, etc.
True
A good example of convolution would be birds and bats both having the ability to fly.
False
If p=.85 and q=.15, a population in hardy-Weinberg equilibrium would have the following genotype frequencies: AA: .72 Aa: .3 aa: .4
False
p2+2pq+q2
Adaptations are considered anything that helps an organism survive it’s environment.
True
Thomas Malthus argued that populations grow faster than the resources that can sustain them and this creates a “struggle for existence.”
True
When individuals of different species mate, they produce fertile offspring.
False
