Early fifth-century philosopher St．Augustine famously wrote that he knew what time was unless someone asked him．Albert Einstein added another wrinkle when he theorized that time varies depending on where you measure it．Today's state-of-the-art atomic（原子的） clocks have proven Einstein right．Even advanced physics can't decisively tell us what time is, becau the answer depends on the question you're asking．
Forget about time as an absolute．What if，instead of considering time in terms of astronomy,we related time to ecology？What if we allowed environmental conditions to t the tempo（节奏） of human life？We're increasingly aware of the fact that we can't control Earth systems with engineering alone，and realizing that we need to moderate（调节）our actions if we hope to live in balance．What if our definition of time reflected that？
Recently，I conceptualized a new approach to timekeeping that's connected to circumstan
ces on our planet，conditions that might change as a result of global warming．We're now building a clock at the Anchorage Muum that reflects the total flow of veral major Alaskan rivers，which are nsitive to local and global environmental changes．We've programmed it to match an atomic clock if the waterways continue to flow at their prent rate．If the rivers run faster in the future on average，the clock will get ahead of standard time．If they run slower，you'll e the opposite effect．
The clock registers both short-term irregularities and long-term trends in river dynamics．It's a sort of obrvatory that reveals how the rivers are behaving from their own temporal frame（时间框架），and allows us to witness tho changes on our smartwatches or phones．Anyone who opts to go on Alaska Mean River Time will live in harmony with the planet．Anyone who considers river time in relation to atomic time will encounter a major imbalance and may be motivated to counteract it by consuming less fuel or supporting greener policies．

Even if this method of timekeeping is novel in its particulars，early agricultural societies a盎真人
lso connected time to natural phenomena．In pre-Classical Greece，for instance，people“corrected”official calendars by shifting dates forward or backward to reflect the change of ason．Temporal connection to the environment was vital to their survival．Likewi，river time and other timekeeping systems we're developing may encourage environmental awareness．
When St．Augustine admitted his inability to define time， he highlighted one of time 's most noticeable qualities：Time becomes meaningful only in a defined context．Any timekeeping system is valid，and each is as praiworthy as its purpo．

不求有功但求无过
We are the products of evolution, and not just evolution that occurred billions of years ago. As scientists look deeper into our genes (基因), they are finding examples of human evolution in just the past few thousand years. People in Ethiopian highlands have adapted to living at high altitudes. Cattle -raising people in East Africa and northern Europe have gained a mutation (突变) that helps them digest milk as adults.
On Thursday in an article published in Cell与天气有关的词语, a team of rearchers reported a new kind of adaptation - not to air or to food, but to the ocean. A group of a-dwelling people in Southeast Asia have evolved into better divers. The Bajau, as the people are known, number in the hundreds of thousands in Indonesia, Malaysia and the Philippines. They have traditionally lived on houboats; in recent times, they've also built hous on stilts (支柱) in coastal waters. “They are simply a stranger to the land," said Redney C. Jubilado, a University of Hawaii rearcher who studies the Bajau.

In201, Melissa Ilardo, then a graduate student in genetics at the University of Copenhagen, heard about the Bajau. She wondered if centuries of diving could have led to the evolution of physical characteristics that made the task easier for them. “it emed like the perfect chance for natural lection to act on a population," said Dr. Ilardo. She also said there were likely a number of other genes that help the Bajau dive.299
