Concept explainers
To explain: The definition of species.
Introduction: It was a difficult job for researchers to describe the origin of living organisms. Different views of the researchers have been put to explain the origin of different organisms on earth. The work of Darwin helped to understand the origin of living organisms with his scientific theory of evolution.
To describe: The role of geographic isolation and reproductive isolation in the process of
Introduction: Species are the group of potentially breeding individuals that share distinctive attributes in nature. The manner in which new species are formed is called speciation. Distinctive traits arise due to natural selection. Reproductive isolation and geographic isolation can lead to speciation.
