What else can I help you with?
True or false the theory of evolution focuses on the evolution of the human species?
False. Evolution is a general theory relating to the change amongst species over time. It is not specific to any particular species, nor even to a group of species, but to all species that have ever existed, are existing and will ever exist.
Why is the giraffe an example of evolution?
All life is an example of evolution. It is the slow change of a species.
Is evolution over?
No, evolution is not over. Whenever the environment changes, and it is changing all the time, life has to adapt. Even without environmental change, slow, gradual honing of species to their niches would continue, and there is also the matter of genetic drift.
What is a species and how do they develop?
Species is a label that is attached to a group of reproductively linked, usually cohabitating organisms. New species emerge from existing species through a process called speciation, which is a result of evolution. For more information, see related questions below.
How can the evolution of one species affect the evolution of another?
The evolution of one species can impact another through coevolution, where changes in one species drive adaptations in another. This can lead to mutualism, where both species benefit, or antagonism, where one species may be negatively affected. Interactions such as competition, predation, and symbiosis can all shape the evolution of species over time.
Scientists break down evolution into which two categories?
There are no separate types of evolution. Evolution is the changing of allele frequencies within populations. This definition encompasses all evolution, from adaptation within a species to the emergence of new major taxa from existing taxa (eg. the emergence of birds from dinosaurs).
Why should research in evolution continue?
The theory of evolution states that all things originated from one common ancestor. The research should continue because it is just a theory, therefore not fact. So anyone can say "Oh that doesn't matter, it's just a theory". But for all we know it could be wrong...
What supports the scientific theory that all species share a common ancestor?
Evolution.
How is DNA evidence used in evolution?
All species have the same genetic code.
Why are there apes if humans evolved from them.?
evolution - apes continued to evolve as well. We came from all mamals, reptiles etc... each species continued to evolve into its own lines. All dogs came from the selective breeding from wolves, and wolves continue to exist.
What is an example of divergent evolution?
Basically, divergence is the "default mode" of evolution. So virtually all species you can think of would be examples of divergence. Even in cases of parallel and convergent evolution, the underlying genomes will continue to diverge. An often used example of divergent evolution in the morphological and behavioural sense is Darwin's finches.
All of the scenarios are examples of evolution with the EXCEPTION of the?
introduction of a new species into an ecosystem. This is an example of migration or dispersal, not evolution, as the genetic makeup of the new species remains unchanged. Evolution involves changes in the genetic composition of a population over time.
