Question

According to Darwin"s theory how did limbless salamander evolved?

Answer 1

The same way as all other animals.

Answer 2

Same as everything else:

1st there was a salamander with legs, time passes, them poof, a salamander without legs.

OR,

1st there was a salamader without legs, time passes, then poof, a salamander with legs.

See just pick a seemingly related starting point, say the magic words "a lot of time passes", then a seemingly related ending point.  Poof, evolution.

Do not worry, in 165 years, no missing link has been found, yet people still cling to the theory with blind faith.  So just make something up.  As in "The King Has No Clothes" no one dares to question you.

They do it all the time on TV and in books.

Answer 3

By the genes for limblessness giving the salamanders who had it (by spontaneous mutation- it happens; genes are very complex things and they break easily) some kind of advantage that allowed them to out-compete their leggier brethren and replace them as the dominant type in that particular environment. Simple as that.

Evolution is only hard to understand if you're a bit thick.

Answer 4

Basically Charles Darwin came up with 4 needed characteristics that allows animals/plants to evolve.  While studying in the Galapagos Islands he realized for a specific species to evolve they  need:

1) To be isolated (on different continents or by water)

2) Reproduction has to be involved (takes many trial and errors)

3) Natural Selection has to occur (the fittest survive the weakest die...like giraffes and long necks if having a long neck to reach the high leaves in trees is needed they'll survive while the shorter neck giraffes die)

4) Have to correctly be fitted sexually (same number of gametes)

Hope this helps...so probably it was a slamander that eventually became isolated by water therefore primarily not using any limbs and they kept reproducing while the ones with the longer legs lives became harder to survive from predators...hope this helps!

Answer 5

Even the salamanders with legs don't use them very much. Every unused organ places the animal at a selective disadvantage. If one is born without one or both pairs of legs, it will survive at least as well as its legged relatives. If it survives, it will reproduce.

Answer 6

probably from some sea floor fish.
