Allopatric speciation.
Allopactric speciation. Geographic isolation. Adaptive radiation can also result from geographic isolation.
the phylum cnidaria contains over 9000 different organisms
Plate movements has lead to dispersion of different organisms over time. Animal and Plant species of different types have been transported and displaced to new environments resulting to introduction of species that did not exist in an area before to become an inhabitant of such place.
No. Evolution explains how and why organisms change over time. It makes no difference to evolution how organisms are generated.
In biogeography studies, similar animals that seem to be closely related are adapted to different environments in nearby areas. Also, in areas that are widely separated animals that seem to be unrelated are observed to have similar adaptations to similar environments in the separate areas.
example of an micro-evolution in an organism?
adaptation of organisms to their environments
Divergent Evolution
Different environments support different organisms by using cycles that each organism needs for example, paralism, mutatilism, and comensilism.
Analogous selection.
Differences among organisms is how evolution occurs. This is because those with differences are sometimes better equipped to survive, so they pass on their differences.
Ecosystemcommunity
Paleontology is the study of prehistoric life, including organisms' evolution and interactions with each other and their environments.
The process by which different organisms develop and diversify from earlier organisms.
The theory of evolution by natural selection. It explains evolution; the change in allele frequency over time in a population of organisms. Why organisms change over time in differing environments.
Evolution leads to varied sophistication levels in organisms...complication of body structure is highly related to environments...which will together create varied lifespan
Different from what? Evolution is the change in allele frequency over time in a population of organisms. So, I repeat, what difference?
During his trip on the HMS Beagle, Charles Darwin observed variations in species among different environments, which led him to formulate his theory of evolution through natural selection. He also observed the diversity of flora and fauna in different regions, the impact of geographical isolation on species, and the adaptations of organisms to their environments.
