Well what you have to do lol
All organisms descended from a common ancestor
DNA helicase untwists the helix at the replication origins. Then the DNA is seperated into a "Y" shape called the replication fork.
Proteins are the main structural and functional components of cells.
Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid. The mRNA sequence is thus used as a template to assemble in order the chain of amino acids that form a protein.
The sequence of a protein is determined by the DNA of the gene that encodes the protein change in the gene's DNA sequence may lead to a change in the amino acid sequence of the protein. The sequence of amino acids of a protein determines protein shape, since the chemical properties of each amino acid are forces that give rise to intermolecular interactions to begin to create secondary structures, such as α-helices and β-strands.

A new species is formed when there is a change in the dna or mutation.
