Speciation refers to the genesis of a new species from an ancestral species. There are two basic ways this can happen. Anagenesis involves one species evolving into a different species. Cladogenesis occurs when one species splits into two or more species. Cladogenesis is of greater interest in terms of biodiversity and is the type of speciation discussed here. Speciation has two primary components: diversification and genetic isolation. The two principal types of cladogenesis are allopatric speciation and sympatric speciation.
Answer is Speciation!
Explanation:
More than a century ago, the first fossils were discovered in Antarctica. During the expedition to the Pole
Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane, and bringing it into the cell. Exocytosis describes the process of vesicles fusing with the plasma membrane and releasing their contents to the outside of the cell. The main similarity is that both exocytosis and endocytosis are involved in transporting big molecules across the membrane using a vesicle and needs energy. The basic differences are that : 1) Endocytosis brings materials to the inside of the cell while exocytosis takes them out. Exocytosis, on the other hand, is described as the process of fusing vesicles with the plasma membrane to release their contents to the external environment of the cell.
