An extremely rare manuscript(手稿) signed by English naturalist Charles Darwin is expected to fetch up to $790,000 at a Sotheby's auction next month.
The document contains a passage from the famous 1859 work On the Origin of Species, in which Darwin put forth his theory of evolution. The document was once thought to be a derted page from an earlier manuscript of the work. But experts now understand it was written in 1865 and nt to the editor of the Autographic Mirror who had requested a signed writing sample from Darwin.
"While some of Darwin's notes and manuscript pages have survived over the last hundred or more years, he was known to keep revising his publications, often throwing away pages from working drafts as waste paper, making them extremely rare," Sotheby's said in a statement.
On the Origin of Species was voted the most influential academic book of all time in a public poll held during Academic Book Week in 2015. The book offers Darwin's revolutionary idea that species evolve over generations in the process of natural lection.
北京德语培训班 Darwin backed up his theory with evidence collected during his 1831-1836 voyage on the H.M.S. Beagle, during which he obrved and collected specimens(标本)from a number of species. On the Galapagos Islands off the coast of Ecuador, Darwin noted that the finches(鸣雀) on the island were similar to finches on the mainland; however, the availability of different foods in each area had led to differences in beak shapes.
The manuscript will be placed on display at Sotheby's in New York between Nov. 30 and Dec 8, and online bids will be accepted between Nov. 25 and Dec. 8. The auction hou estimates that the document will fetch between $600,000 and $790,000.
The auction, which is titled Age of Wonder, will also include a first edition of On the Origin of Species and a copy of scientific paper by Darwin and another naturalist.

Rearchers from Singapore said in their new study that in older adults, doing houwork was tied to a better memory and attention span, and stronger legs, which helps prevent falls. Shiou-Liang Wee, a rearcher said, “Houwork is a purpoful activity performed by many older adults and reprents a significant share of their lf-reported physical activity.”
For the study, Wee’s team investigated nearly 500 healthy Singaporeans between 21 and 90 years of age. Among younger participants, 36% said they engaged in enough physical activity to meet the goal rearchers t as beneficial, as did 48% of older participants. But 61% of younger and 66% of older participants met this target only through houwork, the study revealed.

8% higher among tho who did lots of houwork, compared with tho who did little, Lee’s team found.
And among older participants, balance and the time it took to stand up from sitting, which the investigators ud as an indication of physical ability, were better for tho who did lots of houwork than for tho who didn’t.

Physical activity increas blood circulation to your muscles and your brain, which helps mental function. Houwork can be an important part of your exerci routine. Carney said, “It’s a task you’ve got to plan for. You’ve got to u devices; you’ve got to u equipment. There’s planning involved, so there’s mental exerci along with physical exerci.”
