Question
Can we call human evolution as adaptive radiation?
✓

Answer

No, we cannot call human evolution as adaptive radiation.
Reason:
Adaptive Radiation: It is an evolutionary process where diverse species evolve from a single common ancestor to adapt to different ecological niches
Human Evolution: It is primarily a linear and gradual process (Anagenesis). Human ancestors evolved sequentially over time (e.g.,Homo habilis → Homo erectus → Homo sapiens rather than radiating into multiple distinct species simultaneously from a single point.
