<h3>In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.</h3>

Explanation:
The importance of evolutionary studies is very large, since all organisms and their characteristics are products of evolution. It has an enormous interest applied in topics such as biodiversity conservation, medicine, agriculture, livestock, etc. Evolutionary biology is concerned with understanding the processes that have given rise to the current characteristics of organisms, and explaining why the characteristics of those organisms are what they are and not different ones.
