In phylogenetics, a derived trait is a trait that is present in an organism, but was absent in the last common ancestor of the group being considered. For example, among the tetrapods, having five fingers is the primitive trait - as their last common ancestor bore a five-digit hand.
What is an example of a derived trait?
An example of a derived character is the loss of a tail, a trait that first appeared in an ancestor of apes and man. For example , the trait of having four limbs is a derived character shared at one point in history by amphibians, turtles, lizards, snakes, crocodiles, birds and mammals.

What are derived characters traits?
A derived character is a trait that arose in the most recent common ancestor of a particular lineage and was passed along to its descendants.
What is an example of derived trait on the Cladogram?
Ancestral and Derived Traits in Cladistic Analysis Consider birds as an example. A derived trait in birds is feathers. The trait is present only in birds and was not inherited from a common ancestor of birds and other organisms. An example of an ancestral trait in birds is the presence of eyes.11-Dec-2015
What are 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.
What is the difference between an ancestral and a derived trait?
As a reminder, an ancestral trait is what we think was present in the common ancestor of the species of interest. A derived trait is a form that we think arose somewhere on a lineage descended from that ancestor.
Do perch and chimps share a common ancestor?

Can a derived trait be ancestral?
Ancestral traits and derived traits. Ancestral traits are shared throughout the larger group. Derived traits are present only in a smaller group. The smaller group is defined and identified by having the derived trait.19-Feb-1998
What are derived characters of a tortoise?
Well... Turtles and tortoises are reptiles with rather round hard shells (generally hard), four legs and a tail. They all have scales, lay eggs, and their body heat is regulated by their environment or ectothermic).
How are derived characters used to construct Cladograms?
What is a clade? How are derived characters used in making a cladogram? They separate the organisms by what characteristics they do and do not have.
Is Homoplasy a shared derived trait?
A homoplasy is a character that species share through convergent evolution: it is no indicator of phylogenetic relations. ... 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 on mammals ancestral or derived?
Scientists have uncovered the link between the hair of mammals, the feathers of birds and the scales of reptiles. And the discovery, published today in the journal Science Advances, suggests all of these animals, including humans, descended from a single reptilian ancestor approximately 320 million years ago.24-Jun-2016
What is a shared derived trait called?
Apomorphy – a derived trait. Apomorphy shared by two or more taxa and inherited from a common ancestor is synapomorphy. Apomorphy unique to a given taxon is autapomorphy.
What does derived mean in phylogenetics?
Derived trait. In phylogenetics, a derived trait is a trait that is present in an organism, but was absent in the last common ancestor of the group being considered. This may also refer to structures that are not present in an organism, but were present in its ancestors, i.e. traits that have undergone secondary loss.
