Is the Pentadactyl limb a homologous structure?
The pentadactyl limb is a homology in the pre-Darwinian sense: it is a similarity between species that is not functionally necessary. An animation gives you a good idea of the homologous structure between different species. Figure: all tetrapods have a basic pentadactyl (five-digit) limb structure.Click to see full answer.

In this manner, what is Pentadactyl limb structure?pentadactyl limb A limb with five digits, characteristic of tetrapod vertebrates (amphibians, reptiles, birds, and mammals). It evolved from the paired fins of primitive fish as an adaptation to locomotion on land and is not found in modern fish.Also, how is homology in the Pentadactyl limb evidence for adaptive radiation? Explain how homology in the pentadactyl limb provides evidence for adaptive radiation. It provides evidence for adaptive radiation by having a structure with a common ancestor but differ in function. These type of limbs were first seen in primitive fish in which now, by adaptation, are seen in four legged vertebrates. Accordingly, how is the Pentadactyl limb evidence for evolution? The pentadactyl limb seen in the horse provides an excellent example of how evolution has happened. As the marshy ground became drier, horses with smaller feet were generally faster. They had an evolutionary advantage because they were able to avoid predators.What is a homologous structure?The definition of a homologous structure is an organ or body part that appears in different animals and is similar in structure and location, but doesn’t necessarily share the same purpose. An example of a homologous structure is the human arm as compared to the wing on a bird.
