The formation of goose bumps in humans under stress is considered by some to be a vestigial reflex, [4] though visible piloerection is associated with changes in skin temperature in humans. [5] The reflex of producing goose bumps is known as piloerection or the pilomotor reflex, or, more traditionally, [6] horripilation.
A vestigial response or vestigial reflex in a species is a response that has lost its original function. In humans, vestigial responses include ear perking, goose bumps and the hypnic jerk . In humans
Although structures commonly regarded "vestigial" may have lost some or all of the functional roles that they had played in ancestral organisms, such structures may retain lesser functions or may have become adapted to new roles in extant populations. [4] It is important to avoid confusion of the concept of vestigiality with that of exaptation ...

Biological processes are those processes that are necessary for an organism to live and that shape its capacities for interacting with its environment. Biological processes are made of many chemical reactions or other events that are involved in the persistence and transformation of life forms.
The most important approach to overcoming these challenges is to increase the number of independent (non-pleiotropic, non-linked) characteristics used in the phylogenetic analysis. Along with parsimony analysis, one could perform a likelihood analysis , where the most likely tree, given a particular model of evolution, is selected, and branch ...
