Answer:

The correct answer will be option-C.

Step-by-step explanation:

The evolution of human species in which one species transformed into another species evolves by a mechanism known as anagenesis.

Anagenesis is the mechanism of evolution which transform one species into a different species within a lineage. This process is slow and takes time to form species, therefore, is also known as gradualism or phyletic transformation.

The Homo sapiens evolved from Homo erectus where Homo sapiens overwrites the ancestral species and caused the species to become extinct.

Thus, Option-C is the correct answer.
