As for this wooly mammoth coming back, it remains to be seen if the artificially created embryo is even able to survive in the elephants womb- it probably will, but will take many tries and may result in a less than healthy clone. The micronutrient environment of the womb (ie the concentrations of specific ions in the amniotic fluid) is likely to vary enough between an elephant and a wooly mammoth that this is a tall hill to climb.
From Wikipedia regarding Dolly the Sheep: http://en.wikipedia.org/wiki/Cloning
"Cloning Dolly the sheep had a low success rate per fertilized egg; she was born after 237 eggs were used to create 29 embryos, which only produced three lambs at birth, only one of which lived. Seventy calves have been created and one third of them died young; Prometea took 277 attempts. Notably, although the first clones were frogs, no adult cloned frog has yet been produced from a somatic adult nucleus donor cell."
1/237 using the exact same species.
Also, dinosaurs being spontaneously created with no egg will not happen. Jurassic Park, while awesome, has no basis in science. T-Rexes were likely scavengers, not roaring monsters of death and maiming.
If these scientists want to see a mammoth they should just put a wig on an elephant.Edited by KittensMewMew - 1/17/11 at 11:18pm
