La evolución no tienen ningún punto final en mente.
Si nos creemos las representaciones gráficas de la evolución de las especies que muestran carteles, ilustraciones y camisetas podríamos pensar que avanza como un desfile ordenado hacia una meta predeterminada. Pero no es así.
Evolution has no final endpoint in mind.
If you go by editorial cartoons and T-shirts, you might have the impression that evolution proceeds as an orderly march toward a preordained finish line. But that's not right at all.
Perubahan iklim dapat memperparah stres spesies seperti ikan kod Atlantik yang telah terancam akibat penangkapan berlebih.
Banyak orang mungkin terkejut ketika mengetahui bahwa ikan memiliki telinga, terlebih lagi ketika mengetahui pada beberapa kasus, ikan memiliki indera pendengaran yang tajam.
Climate change could further stress species such as Atlantic cod that already are threatened by overfishing.
Tiny calcified formations inside fishes' ears can be used to trace a fish's life history – and potentially, how climate change has affected its growth and development.
Nearly a year after Hurricane Maria, water is still not restored to all of Puerto Rico.
Many countries collect and store rainwater for use during drought or dry seasons. But this technique is rarely used in the Caribbean, where hurricanes can leave people without water for months.
Untuk sebuah megapolitan, Tokyo begitu kaya dengan pepohonan.
Di dunia yang semakin urban, pohon bisa memberikan perbedaan besar. Sebuah penelitian menemukan bahwa untuk setiap dollar yang diinvestasikan ketika menanam pohon akan memberi keuntungan $2,50
For a megacity, Tokyo is rich in trees.
In an increasingly urban world, trees can make a major difference. One study found that, for every dollar invested in planting, megacities saw a $2.50 return on their investment.
Autumn edible mushrooms, mostly Boletus edulis.
The global mushroom industry is worth $35 billion yearly and growing. But mushrooms and other fungi play important ecological roles that scientists are still learning about – and some may be endangered.

The Galapagos Islands' giant tortoises are one of the world's best examples of evolution. Scientists are pioneering new conservation strategies to save them from extinction and restore their habitat.
A massive fish die-off occurred in Redondo Beach, California in 2011 caused by oxygen-starved fish.
Warming waters due to climate change are losing oxygen, threatening the health of fish and ecosystems.
Ethanol made from corn goes into our gas tanks. Now refiners who pay for the subsidy are complaining of rising costs.
A fight's breaking out over who should pay subsidies for corn ethanol, and it is consumers who may end up paying for any changes.
We need other species to survive for the services they provide and the knowledge they can share.

The presidential candidates should be talking about exploring and cataloguing our biosphere, which holds vital clues for how humanity should navigate the future.
A White House proposal to tax crude oil would address the U.S.‘s perennially underfunded highway maintenance program.
Obama's proposal to add $10 tax to crude oil raises the thorny question of whether the U.S. can continue to fund its highway infrastructure with a fuel tax that hasn't changed since 1993.
Before there was E10, in the 1970s there was ‘gasohol,’ another name for gasoline that had been blended with ethanol.
Ted Cruz opposes subsidies for biofuels and still managed to win in ethanol-friendly Iowa. Is corn ethanol starting to lose its political clout?
Transgenic American chestnuts could soon take root.
Adding a single wheat gene helps the American chestnut withstand a fungal pathogen that nearly wiped these hardwood trees out of the eastern forests they once dominated.
A solar array goes up in New York. Is this the best place to locate solar, given the relatively clean New York state grid?
The wind and solar industries scored a huge win by getting extended tax credits, but research shows this isn't the best policy for lowering emissions through renewable energy.
Tiny termites build mega mounds.
They're the soil-builders that allow Africa's arid savannas to be lush grasslands. What do they do inside their huge mounds – and how does a collective mind allow them to do it?
