Question

LUCA (Last Universal Common Ancestor) is believed to have evolved into which of the following domains?

• A. 1, 2, 3.
• B. 2, 3, 4.
• C. 1, 3, 4.
• D. 1, 2, 4.

Answer 1

The correct option is D 1, 2, 4.

Both prokaryotes and eukaryotes are assumed to be evolved from a common ancestor cell called Last Universal Common Ancestor [LUCA] . LUCA then eventually developed into three different domains- Archaea, Bacteria and Eukarya.
Archaea and Bacteria are prokaryotes and Eukarya have eukaryotic cells.
