Nowadays, molecular pieces of evidence are used to show the similarity between two species as the universal molecule- DNA is present in all living organism from lower to higher organisms which code for the amino acids of the proteins.
The differences and similarities between genomes of two different species confirm relatedness as a mutation in genes can show evolutionary patterns which can be summarized as:
differences between base sequences can show the degree of divergence.
a large number of differences means species diverged long ago.
more similarity in sequence means species are more closely related.
Thus, molecular evidence is used to show species relatedness.
The Calvin cycle is a metabolic process that occurs in the chloroplasts of plant cells. Its main function is to create sugar from carbon dioxide for the plant to use as a source of energy
