Answer 1

The transition from prokaryotic to eukaryotic cells took over a billion years in the history of life on Earth.

Step-by-step explanation:

In the history of life on Earth, it took over a billion years to go from the first prokaryotic cells to the first eukaryotic cells. Prokaryotic cells are simpler, lacking a membrane-bound nucleus, while eukaryotic cells are more complex, with a nucleus and other organelles. This transition, known as the endosymbiotic theory, is hypothesized to have occurred through the engulfment and incorporation of prokaryotic cells by ancestral eukaryotic cells.
