Peru Poison Frog Reveals the Secret of Monogamy

Wow, really?  The One monogamous creature we can find (besides whatever percentage of ourselves) is... a poison tree frog.

(Take from the following)

When the researchers moved tadpoles from both species into different sized pools, they found that the tadpoles grew quickly in the larger pools, which contain more nutrients, but could not survive alone in smaller ones.

That strongly suggests that variable poison frogs don't need to stick together, as their tadpoles can survive in larger pools without feeding from their mothers.

Mimic poison frogs have been forced to take a different path, however.

Their tadpoles cannot survive without the care of both their father and mother, as there is too little natural food in their smaller pools.

Fatherly protection

So the adult frogs stick together.

First off, I really want to know... who thought of testing creatures for Monogamy?  Second, The results are VERY interesting.  The more need there is for a unified family environment, and the harder the struggle to keep that family close, more likely the monogamy is for these frogs.  If this truly is a parallel with humans, that's something to consider.

Again, what a Bizarre planet.
