Rapid speciation under conditions in which there is little competition?
adaptive radiation
What happens in adaptive radiation?
Adaptive radiation occurs when a species occupies a habitat with unoccupied niches
Divergent evolution is also known as?
Adaptive radiation
Why a species is most likely to undergo adaptive radiation?
When there is a sudden and long lasting change in the environment, adaptive radation will occur.
What are Darwin's finches a great example of?
Adaptive Radiation or Natural Selection (:
The wings of robins and the wings of dragonflies are examples of?
adaptive radiation
The rapid formation of many new species as in this case is called?
Adaptive Radiation :)
Are placental mammals in north America and marsupials in Australia examples of adaptive radiation?
No.
What kind of radiation is referred to as adaptive?
Adaptive radiation is a term used in evolutionary biology. It is a process in which organisms diversify rapidly in to new forms. This happens mostly when a change in the environment make new resources available.
What is the term for biodiversity that results from new ancestral species?
Adaptive radiation is the term for biodiversity that results from few ancestral species.
Rapid speciation under conditions in which there is little competition?
adaptive radiation
What happens in adaptive radiation?
Adaptive radiation occurs when a species occupies a habitat with unoccupied niches
What is an adaptive zone?
An adaptive zone is an environment which allows the development of adaptive radiation.
Adaptive radiation is likely to produce several to many?
Adaptive Radiation is likely to produce a cluster of species in a short period of time.
What is adaptative radiation?
Adaptive radiation is the evolution of a new species in a relatively short period of time. When many species share a single ancestor. burst of diversification of a group of organisms into an array of niches. ADAPTIVE CAUSES: • After mass extinction: - Reptile radiation after P-Tr - Mammal radiation after K-T • Novel environment: - Sweepstakes routes • Evolutionary transition: - Conquest of land, air • Removal of a barrier - Return of more oxygenated conditions • Key Innovation - Examples: Flight, pharyngeal jaws
What is the type of evolution by which organisms evolve differences when they are isolated in different environments?
Allopatric speciation.Allopactric speciation. Geographic isolation. Adaptive radiation can also result from geographic isolation.
Divergent evolution is also known as?
Adaptive radiation
