There are more than simply 4 biological compounds in the human body. I suppose to categorise, the question is hinting towards the molecules like Carbohydrates ( Poly and mono saccharides ) Proteins ( Polypeptides Made of amino acids) and Fats. There is also water, but I'm hesitant to class that as a biological compound, as it's not organic.

Explanation:
these are the kinds of questions asked
When a lineage splits into multiple line of descents, then, it leads to speciation. It is a process by which a single population evolves into different species. The process of speciation leads to the development of two or more species as the lineages are splitted. These two evolved species are genetically independent.
Hence, the blank can be filled with 'speciation'.
