The result of plate movement can be seen at "plat boundaries", since this is where the plates collide and form visible results such as mountain ranges, tsunamis, etc.
Answer:
natural selection
Explanation:
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
It is when their is sort of a dent somewhere on your body, dimples are usually found on the face, and sometimes you may only have a dimple on one side of your face
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'.
