So it also goes with spiders and most likely every other living being that swims and crawls and glides and slithers and walks and runs and flys around this mysterious world this interstellar terrarium planet earth...
Like wow damn what the hell and i wonder why the hell didnt the around forty thousand or so known species of other spiders also evolve these mesmerizing color patterns and this weird mating behavior...
Beyond all shadows of any doubt we all should be really grateful that these strange eight legged creatures are relatively really small for if they were relatively really large we all would be really screwed...
Quote: The female spiders have been selecting for the most unique and elaborate dances, therefore, the female is selecting for good genes.
If the female decides to mate with a male that has the brightest colors and unique dancing patterns, it is likely that her offspring will have similarly unique courting advantages and succeed sexually as well.
In contrast if a female were to mate with a male that has a dull color pattern and does not dance appropriately, her offspring will likely have the same coloring pattern and may not succeed sexually, ultimately putting the species existence in danger.
What was just described is an example of runaway sexual selection model. In the runaway sexual selection model, it is to be assumed that "If the genetic correlation between trait and preference is extremely high, this system can "run away" in a positive feedback loop, like a snowball rolling down a snowy mountain and accelerating as it becomes larger and larger."
An effect of this would be that across many generations, male coloration would become more and more elaborate because the male gene for color and the female gene for preference are linked.
The Maratus Volans mating ritual can last anywhere between four and fifty minutes and that is a lot of time and energy invested into a female that may not even mate with that particular male.
