Does speciation occur in specific characteristic and predictable manner in all species?

Answer:

No, speciation doesn’t occur in specific characteristics and predictable manner.

Explanation:

Speciation means creation of a new kind of plant or animal. When a particular species separates from its members of species and develops its own characteristics, speciation occurs.

There are different types of Speciation. In allopatric speciation, species separate due to geographical conditions like waterways or mountain range and evolve into separate species. Whereas in Sympatric speciation, species evolve into separate ones without any change in geographical conditions. Other types of speciation are artificial, peripatric and parapatric type of speciation.  So, these changes are neither specific nor predictable.
