beneficial trait that allows an organism to be better suited for survival and reproduction

• adaptation

• vestigial organ

• human

survival of the fittest; organisms best suited for survival are the ones that successfully reproduce and pass on their beneficial characteristics

A taxonomic category above the kingdom level. The three domains are Archaea, Bacteria, and Eukarya.

• Domain

• Archae

• bacteria

• Eukarya

structures that do not have a common evolutionary origin but are similar in function
