Share 5 Fingers of Evolution/Limiting Factors
Save to Folder
This limiting factor is kept at a delicate balance between two different species and two different populations
Predator-Prey Relationships
In what limiting factor do humans play the largest role in influencing?
Available Habitat
A predictable change in the community over time is defined as:
Ecological Sucession
An organism using courtship behavior in order to find a preferable mate would be categorized under what finger of evolution?
Ring finger - nonrandom mating
An abiotic or biotic factor that restricts the number of individuals in a population is defined as a:
Limiting Factor
True/False: Mutations are not a true source of genetic variation with a population because we have knowledge of how, when, and why they will occur
False
A change in the frequency of an allele within a population over time is defined as:
Genetic Drift - pinky finger
An event that causes a population to suddenly decline to a very low number is defined as:
Genetic Drift - Bottleneck Effect
Organisms moving IN to a population is defined as:
Immigration
What finger of evolution is defined as when individuals in a population are not equal, some are better adapted and more likely to survive and reproduce
Thumb - Natural Selection
Storms, Drought, Flooding, Extreme heat/cold, are examples of what type of limiting factor?
Weather
This limiting factor is seen more often when a population is large and in close contact with one another
Diseases and Parasites
Which limiting factor is missing from the following list: Predators, Available habitat, Weather, Diseases and parasites, competition
Fire
Will smaller populations result in MORE or LESS spread of parasites and disease?
Less
A parasite is introduced into the population that feeds on and eventually kills all humans with blood EXCEPT O+ blood. What type of genetic drift is described here?
Bottleneck effect
A random change in an organism's genetic makeup, which will influence the populations gene pool is known as:
Middle finger - mutations
