Theories
Who came up with the theory of Evolution?
Charles Darwin
What type of adaptation is this: A dog howling
Behavioral
What kind of traits are involved in evolution?
Inherited
True or False: Evolution is a choice
False
How long does it take to see the effects of evolution?
Multiple Generations/A long time
What drives evolution?
Competition
What kind of adaptation is this: The tongue of a frog being sticky due to special cells.
Functional
What is the percent of an allele in a gene pool (how common it is)? (evolution changes this over time)
Allele Frequency
What's the word for how well-adapted a species is to its environment?
Fitness
What was the name of Darwin's Ship?
HMS Beagle
What theory says that newer forms of the fossil record are actually modified versions of older species?
Descent with Modification
What type of adaptation is this: A scarlet kingsnake mimics the colors of a venomous coral snake
Structural
What is the difference between inherited and acquired traits?
Inherited traits are passed down from parents, acquired traits are gained throughout your lifetime.
Does natural selection require a variation in genes or for organisms to be as genetically similar as possible?
Variation
Who came up with the idea of carrying capacity?
Robert Malthus
What is the entire name of the book written by Darwin?
The Origin of Species by the Means of Natural Selection
What is it called when a harmless organism looks like an organism that is poisonous or harmful?
Batesian Mimicry
What is genetic drift?
An accidental change in gene frequency.
What's the difference between the Bottleneck Effect & the Founder Effect?
Bottleneck Effect: Dramatic reduction in population size, leading to a change in allele frequency
Founder Effect: A small part of the population migrates, leading to a change in allele frequency
Why must individuals compete for resources?
Limiting Factors
What does the theory of descent with modification say about all species today?
They descended from one or a few original organisms/types of life.
Explain the difference between the 3 types of adaptations
Structural - Body Parts, Behavioral - Instincts, Functional - Cellular function & Chemicals
Give two examples/explanations of how genetic drift affects populations & thyer allele frequency
One organism not reproducing, one organism reproducing a greater than normal amount
Changes in what lead to evolution?
Genetic Equilibrium/Allele Frequency
What are the five conditions needed to maintain genetic equilibrium?
No Natural Selection, Random Mating, No Migration, No Mutations, Large Population
