Answer 1

There are various factors which are responsible for the rise of the new species. Some of the factors are as follows:

• The phenomenon of genetic drift: This results in genetic change due to random events.
  
• Genetic mutation: There is a change in the genetic composition due to various types of mutagens.
  
• Natural selection: This is the phenomenon of natural adaptation and survival of the organisms takes place on the basis of evolution and adaptation.
  
• Geographical isolation: Certain organisms are isolated on the basis of regions and this prevent breeding between these animals.
  
• Reproductive isolation: There are a different type of reproductive structures developed which prevents breeding of different species.
  
• Other environmental factors resulting in changes.
