Words That Make You Think
A theory of evolution positing spurts of relatively rapid change followed by long periods of stasis.
Punctuated Equilibria
Domesticated dogs are an example of
Artificial Selection
Flowers and their pollinators are an example of
Coevolution
Darwin found that when Finches only eat seed they have this kind of beak
Cone shaped and thick
Selection based on variation in secondary sexual characteristics, leading to the enhancement of individual reproductive fitness.
Sexual Selection
The type of evolution that occurs when organisms from a single species become so different that they no longer can interbreed, yet both groups continue to evolve in a similar direction; the ostrich and the rhea are the result of parallel evolution.
Parallel Evolution
cheetahs being able to run fast is an example of
Natural Selection
Sea turtles and pond turtles are an example of
Divergent evolution
What adaptation cause tortoises to live longer
Thick shell
Evolutionary change away frim the ancestral type, with selection favoring newly arising adaptations.
Divergent Evolution
The loss or gain of alleles in a population due to the emigration or immigration of fertile individuals.
Gene Flow
If a trait helps an organism gain food live longer or reproduce it is
Selected for
Alligators' and Crocodiles are an example of
Parallel evolution
This adaptation makes it easier for flying bird to catch bugs
Grasping Beak
A group of volcanic islands west of Ecuador; formed only 5 million years ago, life could not have arisen there, so the organisms that inhabit these equatorial islands must have come from mainland south America and achieved their present diversity through adaptation and evolution.
Galapagos Islands
In natural selection, a hereditary characteristic of some organisms in a population that improves their chances for survival and reproduction in their environment compared with the chances of other organisms in the population.
Adaptation
If a trait negatively impacts an organisms ability to gain food live longer or reproduce it is
selected against
Birds and bats are an example of
Convergent evolution
Reproduction
The state of a population or species in which successful mating outside the group is impossible because of anatomical, geographical, or behavioral differences.
Reproductive Isolation
The total aggregate of genes in a population at any one time.
Gene Pool
Organism get to select their own triats
Incorrect it is random guess and check
Charles Darwin is a punk because
He stole Wallace's idea
When adaptation happen quickly sweeping across an entire population we call that
Rapid Evolution
The emergence of numerous species from a common ancestor introduced to an environment presenting a diversity of conditions.
Adaptive Radiation
