What are derived characteristics?
A derived trait is a trait that is present in a species but not present in its last common ancestor, meaning the trait arose somewhere in the lineage that descended from the last common ancestor.10-Dec-2021
What is the difference between shared and derived characteristics?
A shared character is one that two lineages have in common, and a derived character is one that evolved in the lineage leading up to a clade and that sets members of that clade apart from other individuals. Shared derived characters can be used to group organisms into clades.
How do Systematists determine if a character is ancestral or derived?
Terms in this set (51) -example: to polarize the character "tail", systematists must determine which state (presence or absence) was exhibited by the most recent common ancestor of this group. -evolutionary units and refer to a common ancestor and all of its descendants.
Is hair on mammals ancestral or derived?

Why can differences in mitochondrial DNA be used as derived characters?
Why can differences in mitochondrial DNA be used as derived characters? - All eukaryotic cells have mitochondria, and all mitochondria have their own genes. because all genes mutate over time, shared genes contain differences that can be treated as derived characters in cladistic analysis.
