different mating patterns
geographic barriers
The development of a new species through evolution is called speciation.
Allopatric Speciation (geographic isolation) can lead to the formation of a new species because the population is split in two smaller populations by a physical barrier (river, canyon, mountain...).
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
a new species arises or forms!
osteogenesis
Reproductive isolation
it may be genetic or envionmental change steadily factor
at present ,yes,but hopefully new scientific advancements will improve the situation
Reproductive variation.
DNA
Yes, geographic barriers guarantee the formation of new species.
macroevolution
The formation of a new species
macroevolution
The phenomenon is called speciation.
