Homework Answers
A shared derived character is made up of two words: ' shared + derived'. Shared character is that character which is common in two lineagss. Derived character is defined as the character which is evolved in the lineage and leads to formation of clade. Which results in deviated from other taxons. That's why shared derived character are used to represent taxons group in a clade. And this clade is known as synapomorphy.

Right option is: Synapomorphy.

What is a shared derived feature? (please select a correct answer) 1. are not homoplasy. so they link two species by a species by a specialized feature some of their older shared ancestors did not. 2. a more recent evolutionary relationship exists since two taxa share an adaptation not all of their shared. 3. the order to put a phylogenic trees is by ancestral characteristics first. how does it relate to evolutionary relationships?
