Species A was recently discovered and its DNA sequence was compared to the DNA of the four previously known species from the same genus. The comparison revealed this particular species is the most recent one, the one that diverged last. Show the mismatched nucleotides between these DNA sequences (mark them and count them) and then draw a phylogenetic tree that shows their relationship. You can draw the tree by hand.

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.
