In genetic mutation no beneficial mutation has ever been recorded that benefits that life form it's self?

Question

Why not?

Lol Dan because I did it by mistake. It was a bit like a un beneficial mutation.

Answer 1

natural selection?? evolution?? hello??

Answer 2

This is simply not true. There are several known examples of beneficial mutations that benefited the organism itself. A good one is the bacteria known as the "nylon bug", which has evolved the ability to digest nylon.

Scientists know exactly what mutation was involved - it was what's known as a "frame shift" mutation, when a chunk of DNA is shifted along. It clearly has benefited the organism, since it now has the ability to digest a new food which is present in its environment.

Of course, "beneficial" depends on the environment. A mutation that is beneficial in one environment - such as the ability to digest nylon, in the environment of waste pools around a nylon factory - is detrimental in another, say where there is no nylon around. But that's how evolution works - organisms that adapt to the environment thrive..

Answer 3

depends if you mean humans modifying animals or a natural/freak mutation in an animals genes that cause them to differ from other animals alike (and not just in looks).
if it's the latter then yes there is, an example is a type of moth that is brown in colour ideal for camouflage in rural areas then a mutation in the colour gene produced 1 grey moth which then led to it becoming one of the most common moths we see today in cities. this was not the moth evolving but as your question says benefits the life form by providing camouflage in urban areas where they could not before.
