A cladogram is a branching diagram that shows the cladistic relationship between a number species. It comes from the greek clados meaning branch and gramma meaning character. It is not to be confused with an evolutionary tree since it does not show the relationship between ancestors and descendants plus it also lacks the ability to show how they have changed over time. The major components of a cladogram are the tip (the start of the lineage), root (the end of the lineage) and node (where two or more lineages combine).
Body organs can be interrelated with other organisms since they are somehow morphologically and physiologically the same.
1. Brain, the brain for most animals are the same, serves the function the same and acts for the many functions of an organism, similarly. This vital organ plays on action-response behavior, management and primal survival instinct, although somehow it's different in structure from the other organisms.
2. Stomach, is an organ wherein the food that is taken in from mouth or opening of a cavity is stored for a short time and is prepared for digestion and metabolic process in the digestive tract or G.I. tract.
