Answer:
Mitosis
Explanation:
A zygote is a fertilized egg. This zygote needs continuous growth in order to develop into a grown adult. The growth involves generating new somatic or body cells through cell division. A parent cell in the zygote divides to produce identical copies of itself. This way, genetic information is passed on the the new arising daughter cells. To do this, the parent cell must first replicate its DNA and the process of separating this duplicated DNA into two identical cells is known as mitosis.
Mitosis is a type of cell division that involves the production of daughter cells that are genetically identical copies of the parent cell and also the same number of chromosomes as the parent cell.
As cells divide, duplication occurs. As cell multiplies, growth is occurring in the organism. The zygote keeps undergoing growth division (mitosis) till it gives rise to all the cells in an adult.
On the other hand, Meiosis is also a type of cell division but it is a division mainly involved in reproduction not growth. Reproductive cells divide to give rise to daughter cells (gametes) that have a reduced number of chromosomes.

Anatomy and embryology gives information on evolution. Anatomy deals with the study of the body structure of the living organisms including the humans. The study of embryos also gives information on evolution. For instance the things that will be present in a fully grown animal can be seen by monitoring the maturation of an embryo. The similarities in early stages disappear on development. For example, the human embryos have a tail like structure at a certain stage of development and gills at one of the stages. The two pair of slits of the gills disappears with the growth of embryo and final pair becomes ear and eustacian canal. This is evidence that humans had tails long ago and also had gills indicating that in the past we were aquatic or marine species.
Embryology gives an idea on how an organism looked at earlier stages. This study supports evolution. The developmental stages of several organisms when studied was found that they are very similar indicating they have evolved from a common ancestor. The anatomy of homologous features in organisms show common ancestry and thus supports evolution.
