Provide an adaptive and a nonadaptive hypothesis for the evolutionary loss of useless organs, such as eyes in many cave-dwelling
Zepler [3.9K]

In order to be able to Provide an adaptive and a non-adaptive hypothesis, the following is required

<h3>What is adaptation?</h3>

It refers to a trait or an integrated set of traits that increases the fitness of an organism. It is the process of improving the fit of phenotype to environment through natural selection.

<h3>What is non adaptation?</h3>

it refers to those traits that do not result in the better adaptation of the organism to its environment, and does not increase the genetic fitness of the organism.

Let us take the case of vain organs. There may be a metabolic value to constructing a vain organ, and subsequently the humans who have misplaced that organ might also have a selective advantage. Also, if the organ is useless, the mutations that disrupt the improvement of that organ would be evolutionarily neutral, and may want to unfold to fixation via genetic drift.

So an adaptive hypothesis as to why an organism may lose useless organs is energy trade offs. The organism may additionally be losing energy in growing and retaining a vain organ, whilst this strength can be higher used someplace else. So an organism that lives in a darkish cave might also sooner or later lose its eyes considering eyes are of no use inside a darkish cave.

A non adaptive hypothesis for the evolutionary loss of organs can be random mutation. If a random mutation occurs that causes an organism to lose its eyes, in a dark cave where it does not use its eyes anyway, it could still survive, reproduce and pass that mutation down.

Sympathetic nervous system vs parasympathetic nervous system
AveGali [126]

Answer:

Differences between Sympathetic and Parasympathetic

1. Anatomical: The location of preganglionic neurons of the autonomic ganglia and the extension of preganglionic and postganglionic fibers are different in these two systems;

2. Pharmacological: In the Sympathetic system we have the presence of Cholinergic fibers (Ach) and in the Parasympathetic system we have the presence of Noradrenergic fibers (NE);  

3. Physiological: They act antagonistically, they rarely work harmoniously synergistically in coordinating visceral activity (balance)
