ancestral trait: this trait varies throughout the order with some species having reduced thumbs or second digits an opposable thumb and, in most species, a divergent and opposable big toe derived trait:ability to more the thumb so that it opposes or comes n contact with the second digit or with the palm of the hand


the grid-cell level. We link the ancestral characteristics data with current populations using the languages and dialects spoken. We implicitly assume that the ancestral traits will be transmitted in a manner that is correlated with the transmission of language, which is itself is an important vertically transmitted trait.

Download the Database. Giuliano and Nunn’s database measures cultural and environmental characteristics of the pre-industrial ancestors of the world’s modern populations, and can be used to assess connections between ancestral characteristics and current economic conditions.


Characteristics that were present in the common ancestor of the entire group of organisms.This character state is called ancestral for the group as a whole.


A ancestral trait is a trait that is shared in common ancestors. Is hair is an ancestral trait. Live birth is a derived trait in species two. Placenta is a derived trait in species 3. If species 3 evolved from species two, then live birth would be an ancestral trait to species 3.


A shared character that is to a specific taxon is a shared ancestral character. In comparison with a shared derived character , it is the difference broadly between the character arising more recently (shared derived, that is, both within and defining a taxon) or instead less recently (shared ancestral).
