Determining the "lowest" life form on Earth is a bit tricky, as life is incredibly diverse and complex. However, we can consider prokaryotes as some of the simplest and most ancient forms of life.
Prokaryotes are single-celled organisms that lack a nucleus and other membrane-bound organelles. They include bacteria and archaea.
Bacteria are ubiquitous and essential for many ecological processes, such as decomposition and nutrient cycling.
Archaea are often found in extreme environments, such as hot springs and salt lakes.
While prokaryotes are simple in structure, they are incredibly diverse and adaptable, making them crucial to life on Earth.
Other contenders for the "lowest" life form include viruses, which are not technically considered living organisms but can replicate within host cells.
Ultimately, the concept of a "lowest" life form is subjective and depends on how we define life and complexity.
