How does taxonomy help us understand relationships among organisms on Earth?

Taxonomy helps us understand relationships among organisms on earth because you can produce a genetic tree diagram which starts from present day animals and goes back to the first early life forms. Scientists will use living organisms and extinct organisms either from fossils, from drawings or from photographs.

label a cell membrane

label b cytoplasm

label c ribosomes

label d dna

the membrane forms the outside of the cell

cytoplasm is the liquid within

ribosomes are the components within that distribute rna

the dna is the genetic make-up
