How does evolution explain different species?

Charles Darwin’s theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Which process causes the change from one species to another?

Evolution is the process by which species adapt over time in response to their changing environment.

What are three different ways that species might naturally evolve?

shows the three main types of evolution: divergent, convergent, and parallel evolution.

How environmental factors could have resulted in the evolution of new species?

Change in an organism’s environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species. Organisms become isolated as a result of environmental change. The cause of isolation can be gradual, like when mountains or deserts form, or continents split apart.

How does evolution happen?

In biology, evolution is the change in the inherited traits of a population from generation to generation. Evolution occurs when these heritable differences become more common or rare in a population, either non-randomly through natural selection or randomly through genetic drift.

How do species evolve through natural selection?

Natural selection is the process through which populations of living organisms adapt and change. Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species.

How do new species evolve?

Biologists believe that new species evolve from existing species by a process called natural selection. Organisms that inherit that favorable new gene are likely to become more abundant than others of the species. Sometimes the population of a species becomes separated into two areas, by geography or by climate.
