Passage 1
In general, the riches of the natural world aren't spread evenly across the globe俄语入门学习. Places like the Tropical. Andes in South America are simply packed with unique species, many of which can't be found in any other places. Until recently, the main explanation for the biological riches concentrated in places like the Amazon Basin was that such places must be engines of biodiversity, with new species evolving at a faster rate than other parts of the world. But now, new rearch on bird evolution may turn that assumption on its head, instead supporting the idea that areas with fewer species actually tend to p弗吉尼亚联邦大学roduce new species faster.
The rearchers say the biodiversity "cold spots" are generally found in environments featuring freezing, dry and unstable conditions. Though the rearchers found the locations with few bird species tend to produce new ones at high rates, they fail to 待到梦醒时分accumulate many species becau the unstable conditions frequently wideawakemake the new life forms die out.
The more well-known " hot spots", by contrast, have accumulated their large numbers of species by being warm, hospitable and relatively stable. Indeed, the rearchers found that the countless bird species that call the Amazon home tend to be older in evolutionary terms. "New species do form in places like the Amazon, just not as frequently as in the dry grasslands in the Andes ," says Elizabeth, an evolutionary biologist.
The rearchers managed to collect 1,940 samples reprenting 1,287 of the 1,306 bird species from South America. Their analysis showed that the best predictor of whether an area would produce new species at a high rate was how many species lived there, rather than climate or geographic features like mountains. Species-rich areas tended to produce new species more slowly.
" Maybe bad environments generate new species more frequently becau there's less competition and more available opportunities for new species," says Gustavo Bravo, a lead rearcher.
The study's findings add new urgency my best of my lifeto protect ecosystems that may look barren, but
may actually be nature's hothous for the evolution of new species.

passage 2
A kind man, Keith Walker, who was 53 years old, kept his own pitbull called Bravo at the W-Underdogs (an animal slippedshelter) overnight and was on his way to pick him up when he saw the flames on December 18.
