Definitions
Change in a genes frequency over time due to random chance
What is genetic drift
Physical differences in coloration, body covering, shape, etc
What is Physical Adaptations
Initial mortality low due to high parental care but rapidly increases with age
What is Type 1
Multicellular
What is Kingdom Animal
Occurs when a few individuals from a large population migrate to an isolated area such as an island
What is founder effect
Variety of genes within a population
What is genetic biodiversity
Too much/too little of environmental factor encourages fat storage, water conservation, salt tolerance, etc
What is physiological stress
Competition for food, spread of disease, waste accumulation (biotic factors)
What is density-dependent factors
Warm blooded that bear live young
What is Class Mammal
Competition between members of same species
What is Intraspecific
Defines the specific abiotic factors that are survivable for a species
What is optimal range
Result of sudden decreases in population size, reduces gene pool & encourages in-breeding
Occurs when a populations growth rate slows down due to environmental resistance factors
What is Logistic Growth
Animal with a spinal cord
What is Phylum Cordate
Symbiotic relationship where both organisms benefit
What is mutualism
Actions taken; migration/marking territory, etc
What is Behavioral Adaptations
Natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.
What is sexual selection
Sudden population crash due to a lack of resources
What is dieback
Collar bone, grasping hand with fingers
What is Order Primate
Dividing up a resource, reducing competition
Role of an organism within its ecosystem- relationship with other species
What is niche
Have analagous structures that perform a shared task but are structurally different
What is convergent evolution
Few offspring, high parental care, and slow maturity
What is K-Selected
Upright posture, large brain, flat face
What is Family Hominid
Competition between different species that cannot occupy the same niche
What is Interspecific
