Islands are relatively isolated environments, so there it is less likely that an existing species will move in and outcompete a developing one, and also easier for an existing species to die out since there aren't external populations to replace them. This instability means that the environment can change more quickly, and therefore species must adapt more quickly, compared to the relatively stable environment on the mainland.

Why did Darwin find 9 different species of finches on the Galapagos Islands?
The species of finches Darwin found were so varied because they had migrated over time to islands of different vegetation, and they adapted to better suit their new environment. Over time, the finches became so different from each other that they turned into new species.
After a group becomes separated from population a new may from?
A new species may form.
Why did Darwin say the finches on the Galapagos Islands were new species of finches?
They could no longer reproduce with the finches from South America. A+. Tony B.
What is the galapagos effect?
We all know that there is a kind of bird on the galapagos islands which is different between the two neighbouring islands. And it ended in reproductive isolation.That means that if you are isolated long enough from outside forces, like species on the Galapagos island, you evolve and are transformed into a new species, unlike those visible anyplace else.
Why did Darwin say the finches on the galapagos lslands were new species of finches?
Darwin did not say this. Darwin collected finches from the Galapagos islands, believing them to be other words. It was the famous ornithologist, John Gould, who confirmed that 12 samples were all finches, but with enough minor differences for them to be considered new species. While it was Gould who called them new species, it confirmed to Darwin some of the ideas he'd had about the stability of species, how one colony of organisms can split up and adapt to a new environment.
Why doe new species often form new on new islands?
they evolve to fill new niches
Why do new species form on new islands?
they evolve to fill new niches
Can new species be created from existing species?
Yes, they can. It happens quite often (comparatively speaking; evolution of new species can take millions of years) and is the major way of new species arising. For example, Darwin's finches were originally the same species, but because of the separation across the Galapagos Islands, they developed differently to the point they became unique species.
What does a new species form?
Evolution .
What is an effect of adaptive radiation?
speciation
What did Peter and Rosemary grnt notice in the galapigos islands?

What is the process by which new species form?

What the general term for the process by which new species form?
The general term for the formation of a new species is speciation.
Are the Solomon Islands part of Papua New Guinea?
Solomon Islands is a part of Melanesia since Melanesia includes the islands of New Guinea, Vanuatu (the former New Hebrides), New Caledonia, the Solomon Islands, and some smaller neighboring islands.
Why did Darwin say finches on the Galapagos islands new species of finches?
That they were evoled from on specie of finches.
Where are the charam islands?
