Heredity is the cause of similarities between individuals. This is the reason that brothers and sisters with the same parents resemble each other and with their parents.
Or we can say that heredity is the phenomenon of inheritance of traits or features of the parents to the offsprings or progeny.
Variation is the cause of differences between individuals.  This is the reason that brothers and sisters who do resemble each other are still unique individuals.
The heredity and variations play an important role in the formation of a new species.
The biological science which deals with the mechanism of heredity and cause of variations in living beings is known as genetics.
Evolution:-
We can make the following two clear-cut observations regarding the living world:
  1. The living world comprises a rich diversity of animal, plants, and microbial life.
  2. All living organisms appear to be well fitted for the problems posed by the environments in which they live.

It is possible that either the characters of organisms are fixed and have remained so since the origin of life, or they are mutable and their diversity and adaptability have unfolded progressively with time. The dynamic process is called evolution.
Evolution has been defined as a gradual orderly change from one condition to another.

We can add  –S, -es, -ves or ies  to show that there is more than one noun.  For example,  we say many birds, four biscuits, six brushes. But for the students of  Class 2 , it’s very difficult and confusing to understand where to use  s , es, ves or ies  in the form of many. Don’t worry, it looks difficult, but it is very easy as in grammar each concept has a set of rules that need to practice. Noun ending with  –s, -x, -o, -sh, -ch, and –ss  form plurals by taking  –es. Look at these pairs of words: Bus – Buses Brush – Brushes Continue ..... Click here ...
