Rivers are natural boundaries for evolving populations. But scientists don't agree whether they create new species or just help maintain them. Research using birds' molecular clocks provides some answers.
A theory is not meant to be a final statement of how things are, but just the latest stage of ongoing research and new discoveries.
Sulawesi, part of the biogeographical region of Wallacea, is home to tarsiers – tiny, goggle-eyed creatures look more like mammalian tree frogs than monkeys.
The central islands of Indonesia, also known as Wallacea, is a place of wonder, a living laboratory for the study of evolution.
