Raynaud's phenomenon.
Scleroderma is a group of autoimmune diseases that may affect different parts of the body with special intensity in the skin. Some of the affected structures may be blood vessels. Because of this, when exposed to cold, vasoconstriction occurs and the Raynaud's phenomenon is manifested in the extremities of the body.
The evolution of similar forms in different lineages when exposed to the same selective pressures is<u> convergent evolution. </u>
<u></u>
Convergent or divergent evolution are related to the involved groups, the environments, the selective pressures, and the way in which organisms deal with them to achieve a better adaptation increasing their fitness.
<h3>
What is convergent evolution?</h3>
Convergent evolution is the emergence of phenotypical similarities in different groups independently from each other.
Convergent evolution occurs when two or more taxonomic groups share the same traits or characteristics even when they do not share a common ancestor.
Usually, this is a pattern observed in groups that are exposed to the same or similar environmental pressures. The development of these similar phenotypes is related to higher fitness and competitive ability.
The evolution of similar forms in different lineages when exposed to the same selective pressures is <u>convergent evolution. </u>
