Root Explanation

Synapomorphy → It is formed from "syn-" (meaning together) and "apomorphy" (from Greek "apo-" meaning away and "morphe" meaning form or shape). The term refers to a shared derived characteristic that is present in a group of organisms, indicating a common evolutionary ancestor.

Memory Tip

Think of 'together' ('syn-') and 'form' ('morphe') to remember that 'synapomorphy' refers to a shared form or characteristic among related organisms.
