What is Considered a Fundamental Evolutionary Divergence

Question

What is considered a fundamental evolutionary divergence?
A) Distinction between spices
B) Distinction between Plantae and Animalia
C) Distinction between genes
D) Distinction between prokaryotes and eukaryotes
E) Similarity between prokaryotes and eukaryotes

Accepted Answer

The distinction between prokaryotes and eukaryotes is considered a fundamental evolutionary divergence because it represents a major split in the tree of life. Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles, while eukaryotes are more complex cells that have a nucleus and other membrane-bound organelles. This distinction is thought to have occurred around 2 billion years ago and represents a major step in the evolution of life on Earth.
