Two awesome findings in the world of biology today. Firstly biologists in the crater of a volcano found a new species of Rat that is almost a meter long.. Meanwhile, a study shows that severed gecko tails perform complex movements.
The giant rats, having never encountered mankind until now, are completely tame and unafraid of man. knowing how good pets rats make, I have to admit wanting one of these as a pet just so I could have a pet that is as awesome as a pet rat but the size of a cat or small dog...
The gecko tail thing, however is just amazingly cool and yet another example of evolution coming up with great and weird solutions to problems. if the gecko's tail just falls off, the predator is likely to still go after the rest of the gecko, if it moves rhythmically, the predator is likely to ignore it after a few seconds once it sees it is a pattern, by having complex non-deterministic movements, the tail can lure the predator away from the gecko, and given how fast it is, can perhaps even evade the predator itself.
Like I said, totally awesome!
