[00:01.14] | Hawaii's 20 surviving species of honeycreeper also evolved from just a few individuals |
[00:07.15] | Compared to seabirds, |
[00:08.50] | honeycreepers are poor fliers |
[00:10.88] | So how did the ancestors of these forest birds and Hawaii's other castaways get here? |
[00:16.49] | The answer may be blowing in the wind |
[00:19.73] | Even the gentlest breeze can have a huge impact |
[00:23.73] | Tree ferns stir and release their lightweight spores |
[00:27.36] | Thermal updrafts can carry the spores 30,000 feet into the jet stream |
[00:32.25] | And there are even animals designed to ride these high-altitude air currents |
[00:36.92] | Near-weightless spiderlings are expert ballooners, |
[00:40.45] | catching the wind with their gossamer threads |
[00:43.49] | Like spores,they, too, can hitch a ride on the jet stream |
[00:47.62] | Enduring temperatures of minus 30 degrees centigrade, |
[00:51.46] | a spider can cross the breadth of the Pacific in a matter of days |
