The Amazon basin is well known for its wide variety of species, but the rainforest might owe some credit to the mountains as a source for that rich diversity.
A new study found that populations of poison frogs made their way from the Andes to the Amazon about a dozen times over the last 10 million years. Scientists suspect that the mountains have long been supplying the jungle with other species of plants and animals, too.

Whoda thunk it?
I have a plastic blue dart frog on the leaf of a bromeliad in my office.

Evolution in Your FaceLake Victoria, Africa's largest lake, is home to more than 300 species of cichlids. These fish, which are popular in aquariums, are deep-bodied and have one nostril, rather than the usual two, on each side of the head. Seismic profiles and cores of the lake taken by a team headed by Thomas C. Johnson of the University of Minnesota, reveal that the lake dried up completely about 12,400 years ago. This means that the rate of speciation of cichlid fishes has been extremely rapid: something on average of one new species every 40 years!

I loved the pic’s. Thanks for posting this.
Oooo, pretty!
I read that the frogs need to eat poison ants & bugs to maintain their “poisoness” (is that a word?). IOW, without poison in their diets, they’d just be bright pretty meals with a high extinction rate.
