Question

Scientists now use domain Eukarya to group together the kingdoms of eukaryotic species, which include plants, animals, protists, and fungi. Which statement about the evolution of eukaryotes supports the grouping of the kingdoms into domain Eukarya?
A. All eukaryotic species descended from a common eukaryotic ancestor.
B. Each eukaryotic kingdom descended from a unique prokaryotic ancestor.
C. Species in the four eukaryotic kingdoms evolved independently of one another.
D. Protists evolved first, then the fungi appeared, and then plants and animals.

Answer 1

Answer: Option A

Explanation:

Scientist used the domain Eukarya which comprises the togetherness of all the eukaryotic species. They have been put together because all of the  eukaryotic species have their recent common ancestor as eukaryotes.

The first eukaryotic cells, which had nucleus originated 2 billion years ago which had organelles. They explain the endosymbiotic theory.Most of the eukaryotic species that have been evolved from this.

Eukaryotic species have been evolved from another eukaryotic species and share some similar characteristics.
