if the old species adapt to a new environment the old will get wiped out and the new will reproduce. :D
i dont know ask your teacher!!
Physical isolation leads to evolution of new species. For example in Australia, you have physical seperation from rest of the world. Here you have Kangaroos. Which are found nowhere else on earth. Here only you found platypus and echidna. The only mammals, which lay eggs. Here the kangaroos are premitive mammals. After the birth of the baby it travels to the bag, placed in front of the abdomen. From it travels to the mammary gland and sucks the milk. They are very small in size at the time of birth. So egg laying mammals must be present all over the world. They must have disappeared from rest of the world. ( Like the bird DODO.) So this is not the correct answer and need to be edited by expert in this field.
Scientists infer that species that have similar body structrues and development patterns inherited many of the same genes from a common ancestor.By comparing the sequenes of nirogen bases in the DNA of differnt species, scientists can infer how closely related two species are.
natural selection may determine traits that get passed along genetically through survival of the fittest. After a time the species is no longer recognizable.
One of the species may become so different that they will be separate species.

Geographic isolation of a common ancestral species of finches
Isolation
Galapagos Finches (Darwin's)
If the species is prevented from producing fertile offspring - the species will eventually become extinct.
Isolation from the mainland.

Their genes might mutate in different directions, so once their genes do not match up, a new species will be made.

Any factor that in nature prevents interbreeding between individuals of the same species or of closely related species, for example geographic separation is itself a reproductive isolation because is a factor that prevents interbreeding. -extinction of one species -production of infertile offspring -development of physical differences
1. When new species form.2. When a group is separated from the rest of its species.3. When members of the isolated group can no longer mate with the rest of species.
Only one or two local subspecies of the cougar, such as the Florida Panther, are endangered. The species as a whole is in no danger.
The taxon species can be defined by reproductive isolation, which refers to the barrier that stops individuals from different species from producing viable offspring. This isolation can occur through mechanisms like behavioral, temporal, or genetic differences that prevent successful mating or offspring production between populations.
Potential mates meet, but choose members of their own species. Involves species or mate recognition through cues such as visual stimuli (plumage, courtship displays), auditory stimuli (calls), and chemical stimuli (pheromones).Behavioral Isolation: form of reproductive isolation in which two populations have differences in courtship rituals or other types of behavior that prevent them from interbreeding.
There is only one species of raccoon in all of North America - the common (or northern) raccoon - Procyon lotor.
