Levels of Org
The smallest unit of a living thing
Cell
What an organisms role is within it's environment
Niche
A type of population growth that levels off around carrying capacity
logistic
The dude that wrote the actual book on evolution
Charles Darwin
A piece of evidence that allows us to see what organisms looked like in the past.
Fossils
The difference between a population and a community
Population is just one species, community is multiple
A type of symbiosis where one organism benefits and the other is harmed
Parasitism
A type of growth that increases rapidly and exceeds carrying capacity
exponential
The driving force behind natural selection
The environment
A similar structure that has a different purpose in mammals, like a bat's wing and a human hand
Homologous structure
The biological definition of a species
The range of tolerance at which organisms are able to survive the best
Optimum range
The amount of organisms that an ecosystem can support without collapsing
Carrying Capacity
A type of selection that is driven by mate choice
Sexual Selection
A different structure that serves a similar purpose, like the wing of a bat and wing of a bird
Analogous structure
The correct ranking of organization from species to biosphere
Species - population - community - ecosystem - biosphere
Symbiosis
Density dependent
One of the four factors that can encourage natural selection
physiological stress, predation, competition, sexual selection
A left-over useless structure that tells us about the evolutionary history of an organism
Vestigial structure
What an ecosystem considers but a community does not
A type of symbiosis where one organism benefits and the other is unaffected
Commensalism
An example of an animal with a type 2 survivorship curve
Birds
When an organism has the best adaptions to survive and reproduce the most within it's environment
Fitness
Tells us how closely related organisms are based on the code in the DNA
Genetics
