natural selection
Yes
your mom, it's always the answer!
instantaneous speciation
yeahs
There is one way that new species can develop. The only way a new species can develop is from mating.
A species is a group of individuals that share the same characteristics. Humans are one kind of species. There are many main species and subspecies as well.
Speciation
Reproduction occurs in two main types sexual and asexual. Asexual is the reproduction in which involves only one individual from a species. Most Asexual reproduction occur in single cell organisms. Example of asexual reproduction can be found in self pollinating plants. Sexual reproduction occurs when two individuals trade genetic information to produce a new individual for a species.
Carbon dioxide is the main one.
Speciation is the best term to describe a new species developing from an existing one.
Yes, it is the largest species, and is found in two species, the bush and forest varieties.
Species don't simply "appear" all the time. The development of new species takes thousands of years. According to the theory of evolution, (which mind you, is a theory and not a law) if you take two identical pairs of birds (a male and female) and release them in two very different environments, in several thousand years, (assuming the birds survive the new environment) the birds might have decendants of very different colors, or shape, or diet. Cross breeding is another way, taking two species of the same kind of animal (Two species of fruit flies) and having them mate might produce a new kind of animal Ligers are a cross between a lion and tiger, and yes, they do exist
