Likewise, how did eukaryotic cells evolve?

The first eukaryotic cells - cells with a nucleus an internal membrane-bound organelles - probably evolved about 2 billion years ago. This is explained by the endosymbiotic theory. The small cells were not digested by the large cells. Instead, they lived within the large cells and evolved into organelles.

Likewise, how many times did eukaryotes evolve? By this view, the origin of eukaryotes and the origin of multicellularity would seem largely equivalent. Yet, eukaryotes evolved only once in the history of life, whereas multicellular eukaryotes have evolved many times.

how was the first eukaryotic cell formed?

Eukaryotes are organisms with a nucleus. The oldest evidence of eukaryotes is from 2.7 billion years ago. Scientists believe that a nucleus and other organelles inside a eukaryotic cell formed when one prokaryotic organism engulfed another, which then lived inside and contributed to the functioning of its host.

What role did endosymbiosis play in the evolution of eukaryotes?

Endosymbiosis led to the evolution of eukaryotic cells with mitochondria and chloroplasts. It allowed these kind of eukaryotic cells to gain a reproductive advantage over their neighbors when the mitochondria, a rich source of energy, moved in with them.
