Seven Legged Lamb

Yes, evolution has flexed it’s impressive muscles and produced the world another crazy critter. Back in February we heard about Stumpy, the four legged duckling and this time we’ve got a Lamb with Seven legs.

The crazy one-off-being-a-spider animal has three hind legs, two forelegs and two extra legs that hang useless behind its forelegs. Alas all the effort of building extra legs has left the poor polydactyl without a bowel, which means he’s going to be put down.

Still, it’s pretty fabulous if you ask me. Just imagine how high the wooly-jumper-that-never-will-be could spring if it mastered the use of all of it’s seven legs?

It’s for things like that that is why taxedermy was invented.

Poor sod, not having a bowel. How does he cope with that?

Williams said he believed an error during embryo formation had resulted in the lamb being born polydactyl — with many legs — a condition that occurs once in several million sheep.

See that CANNOT be a result of evolution, how would that lamb benefit over all other lambs? Please insert “lamb chops” joke…..

That’s precisely why it’s evolution. This random mutation hasn’t given this sheep any advantage, but suppose the next sheep that gets born with this does have a bowel, and suffers no ill effect of the extra legs. Given many generations of this, future sheep may learn how to make better use of their many legs, and thus the super springly sheepies have evolved…

Basically genetic mutation is evolution!

Taken from http://www.darwins-theory-of-evolution.com/-

Darwin’s general theory presumes the development of life from non-life and stresses a purely naturalistic (undirected) “descent with modification”. That is, complex creatures evolve from more simplistic ancestors naturally over time. In a nutshell, as random genetic mutations occur within an organism’s genetic code, the beneficial mutations are preserved because they aid survival — a process known as “natural selection.” These beneficial mutations are passed on to the next generation. Over time, beneficial mutations accumulate and the result is an entirely different organism (not just a variation of the original, but an entirely different creature)

Important 2 words there, BENEFICIAL MUTATION. I was always led to believe that evolution is only a result of an animal/plant evolving to adapt to its current state of life so that its way of life is easier, so again I ask how would that sheep benefit over the others? Especially as 2 of its legs didn’t work…..

Yes, but you can’t always have a beneficial mutation. There will always be non-beneficial mutations (probably more than the beneficial ones). The mutations are random. Thus you cannot have evolution without random (beneficial and non-beneficial) mutations.

Also for evolution to occur, you need some change to the genetic make-up of an animal. This is done in two ways;

  1. Sexual reproduction;
  2. Random genetic mutation.

Sexual reproduction only “mixes up” the genes within the gene pool — no new ones are made. The only way to make a new gene is by random mutations. Thus mutation causes evolution.

Hence, by the above dodgy proof, Evolution requires Mutation, and Mutation implies Evolution. And so any kind of mutation justifies me calling the title of the article “More Freaky Evolution”.

Now hush and join me in the pointing and laughing at the freaky sheep.

I shall bow to your Rob superiority when I see a field of 7 legged sheep then :P
