Want this question answered?
If its environment merited them to need short legs or short legs made them survive longer, then a species would evolve short legs.
Because their total lifespan is very short.
It takes a certain amount of time depending on the creature. You cannot tell how long or how short it can be. It could take a generation or a thousand generations. It all depends on the environment. The traits that species acquire are determined by what the environment selects. If the environment changes rapidly, then the species is going to evolve more quickly to fit the new environment, or in some cases, the environment changes too quickly for the species to evolve in which extinction can occur.

punctuated equilibrium
Thier prokaryotic origins and their ability to adapt quickly and evolve in a short time period.
I haven't reviewed this in a while but shouldn't it be life spans? The shorter the lifespan, the more generations within a certain time frame there are.
yep[sorry if this is a short answer]
Many different ways. The vast majority of mutations cause a very short life and/or poor health in one way or another. A select few however wind up being beneficial, and evolve the creature slightly, allowing it to better survive in it's environment newtest3
It might not but some animals can adapt very quick so it also might.
