Question

multiple select question
select all that apply
select all evolutionary mechanisms that were important in the early evolution of eukaryotes.
□ artificial selection
□ evolutionary bottlenecks
□ engulfing other cells
□ horizontal gene transfer

Explanation:

Artificial selection is a human - driven process and not relevant to the early evolution of eukaryotes. Evolutionary bottlenecks can reduce genetic diversity but were not key in the origin of eukaryotes. Engulfing other cells (endosymbiosis) is a widely - accepted theory for the origin of mitochondria and chloroplasts in eukaryotes. Horizontal gene transfer can introduce new genetic material and was important in early eukaryotic evolution.

Answer:

C. Engulfing other cells, D. Horizontal gene transfer
