Charles Darwin
Who created the Theory of Evolution?
|
Disruptive Selection
What type of selection favors organisms' extreme forms(2 traits) of a particular gene/trait? Draw a graph
|
Founders Effect and Bottleneck Effect
What 2 types of effects fall under the topic of genetic drift? (The topics found in the slide show)
|
"From evolution comes natural Selection and that Evolution itself changes from generation to generation and NOT person to person."
What is the Theory of Evolution?
|
Stabilizing Selection
What type of selection favors organisms' with an "average" form of a particular gene/trait? Draw a graph
|
A small group of organisms from a larger population migrate or drift to a different area. The result is different allele frequencies in the new population.
What is the Founders effect in your own words?
|
Lamarck's theory: Parents give/pass on their traits and organisms move to perfection for life.
The problem is that Lamark did not understand genetics. Lammark's theory shows that a parent who knows how to play soccer automatically has a kid who knows soccer. This is not true.
What was Lamarck's theory and, why is it wrong?
|
Directional Selection
What type of selection favors organisms' extreme form (1 extreme trait) of a particular gene/trait? Draw a graph
|
The population is suddenly reduced causing a change in the population’s gene pool.
What is Bottle Effect in your own words?
|
Gene mutation is a random change in an organism's genotype that might shape the species while evolution itself is showing a change from generation to generation.
What is the difference between a gene mutation and evolution?
|
Disruptive Selection
What type of selection creates a new species?
(Directional Selection, Stabilizing Selection,Disruptive Selection) |
It gives new and random traits to an organism that can increase, stay the same, or lower an organism's fitness depending on if the trait was favorable in the habitat.
What role do mutations play in natural selection?
|
James Hutton and Charles Lyell were geologists, and Malthus studied the population of humans; the other scientists were ecologists who studied the evolution of animals.
What is the difference between the scientists James Hutton,Charles Lyell, Malthus than all the rest of the 5 big evolutionary scientists? (Year, Age, and Name do not count as a difference.)
|
Stabilizing selection
Which type of selection does the weight of an infant fall under?
|
Physical Barrier and Lack of resources like food, water, and/or mates
List 2 reasons why genetic drift occurs in a population?
