What’s the first step to allopatric speciation *?
This has been the primary process through which new species are created for many years. This type of speciation often occurs in three steps. The first step is to physically separate the people, which can be caused by slow, long-lasting geological processes like uplifting of land or the movement of glaciers.
Why is an ancestral species more likely to give rise to multiple descendent species on an archipelago than on an equal sized area of mainland?
Why is it more common for an ancestral species to produce multiple descendent species in an archipelago rather than an equally-sized area on the mainland? A: Archipelagos are more likely than other areas to have favorable mutations because people try to adapt to the specific conditions of their island.
Which one of the following conditions is necessary for speciation to occur?
For speciation to occur, two populations must be created from one population. They must also evolve so that individuals from both new populations cannot interbreed.
What is speciation and natural selection?
Speciation refers to the evolutionary process that leads to the creation of a new species. Natural selection can lead to organisms that are more likely survive and reproduce, and eventually to speciation.
What is a result of natural selection?
Natural Selection is the process by which living organisms adapt to change. Natural selection is the process by which favorable traits are passed down through generations. Natural selection can result in speciation where one species gives birth to another.
What is natural selection definition for dummies?
Natural Selection is the process by which organisms most suited to their environment survive, and then pass on their genetic traits to subsequent generations. However, organisms with less adaptability fail to survive and multiply at a slower rate and are often eliminated from an ecosystem.
