Human is a complex organisms because humans are made up of trillion of cell and a lot of system and organ .Some of the major systems are blood circulatory systems, the skeletal system, the digestive system, the nervous system and the respiratory system. Most of which are grouped into organ systems that have specialised functions.
Due to billions of years of evolution, humans share genes with all living organisms. The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us.Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.Besides similarities in anatomy and behavior, our close biological kinship with other primate species is indicated by DNA evidence.NA is thus especially important in the study of evolution. The amount of difference in DNA is a test of the difference between one species and another â and thus how closely or distantly related they are.
