What does derived characteristics mean in biology?
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.
What is a derived characteristic of a Cladogram?

How do you identify derived characters in a cladogram?
Derived characters that are on the main, bottom line are found in all the organisms after that point. If a derived character is not found in all the later organisms, it is located above the main lower line, on a separate branch. For questions 1- 8, match each letter on the cladogram to its character.

What is the opposite of derived trait?
From Wikipedia, the free encyclopedia. In phylogenetics, a primitive (or ancestral) character, trait, or feature of a lineage or taxon is one that is inherited from the common ancestor of a clade (or clade group) and has undergone little change since.
What is the difference between a shared derived characteristic and a shared ancestral characteristic?
An ancestral character is shared with the species ancestral to more than one group: it can lead to different groups being classified together. A shared derived character is shared by the ancestral species and a single group: it is the only reliable guide to inferring phylogeny.
Is hair a derived trait?
Hair is derived for mammals (relative to other [non-mammalian] vertebrates), but ancestral for humans, because the closest relatives to humans, gorillas and chimps, also have hair. Loss of hair is thus a derived feature for whales, among the mammals.
What is a derived condition?
Conversely, a trait that appears within the clade group (that is, is present in any subgroup within the clade but not all) is called advanced or derived. A primitive trait is the original condition of that trait in the common ancestor; advanced indicates a notable change from the original condition.
