Question

Are all species related?

Answer 1

Hint: Species are the smallest among the hierarchy of the classification of the plants and the animals. They are a group of inbreeding species. The species vary from each other on the basis of various families and the order they belong to.

Complete answer:
Species are a group of interbreeding organisms. It is the smallest taxonomic rank and the basic unit of classification of an individual that also plays an important role in biodiversity. This group is the largest group that includes the various number of organisms consisting of their female and male counterparts for the process of mating. By the process of sexual reproduction, fertile individuals are produced by them. In the binomial nomenclature, every species is given two names - a generic anime and a specific name. When the genes of one species are exchanged with the genes of the other species then the new species are evolved. Then they either mate with other species or they will become extinct.
The process of the mating of the two different species belonging to the same genus is called Interbreeding. It helps in uniting the different genetic factors together. This results in a change in the species population and the gene pool composition. As the new alleles are introduced in the gene population resulting in an increase in the variability in the population and thus leads to the formation of certain new traits.

Additional information:
Genus: Genus is a taxonomic rank that is used to classify living organisms, fossils as well as viruses. In the binomial nomenclature is the generic name is the first name of the individual. It is a larger rank than the species.
Family: Family comes in between the genus and the order among the hierarchical taxonomic rank. It helps in the study of the evolutionary characteristics of the organisms. In this, a specific suffix is used for naming which is 'aceae'.
Order: It is the taxonomic rank which is the classification of the organism and recognized by the nomenclature codes. It consists of the family which is a set of similar nature or character.

Note:
The concept of species was first introduced by Linnaeus. It was the word that was taken from the Greek word taken from the bible. Around 8-8.7 million species are known to date. However, out of these only $18-20\%$ of the species were described till now.
