Answer 1

The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as prokaryotes, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.

Answer 2

A researcher investigates a blood disease carried by birds. She isolates an organism from the blood of an infected bird.
