Book Review: Annie's Box


Keynes, Randal. Annie’s Box: Charles Darwin, His Daughter, and Human Evolution. London: Fourth Estate, 2001 (Published in the North America in 2002 under the title Darwin, His Daughter, and Human Evolution: New York: Riverhead Books, 2002)


If you’re curious about Charles Darwin, the man, look no further than Randal Keynes’ touching biography of his great-great-uncle. It’s all here: from the Darwins’ marriage and first home in London to the details of life at Downe House, Emma’s widowhood, and Annie’s Box, a writing-case which symbolizes the heartbreaking death of Darwin's ten-year-old daughter. The account spans from the time Darwin decided to “Marry – Marry – Marry. Q.E.D.” in 1938, dipping into some history at Cambridge and aboard the Beagle, until Emma’s death in 1896, and includes a deeply personal look at life along the way.

Keynes pays particular attention to Darwin as husband and father. Darwin, who adored his family, exhibited “a fine degree of paternal fervour” with his ten children, playing on his hands and knees with them, never silencing their "howls and screams,” and even allowing them into his study while he worked. Of all the children, Darwin doted most on Annie, his cherished, eldest daughter, who was the apple of her devoted father's eye.

On April 23, 1851, just two days after Easter, Annie died, possibly from tuberculosis. Paradoxically, Darwin’s religiosity suffered its final blow at this holiest time of year for Christians. Separated from his wife during Annie’s demise, Darwin could not draw on Emma’s religious fortitude to comfort him or to interpret Annie’s death, and he could not find the consolation he needed from the Church. Although Darwin’s theory of evolution was already well developed by the time Annie died, Keynes juxtaposes Darwin’s darkening sense of nature (and his efforts to understand suffering and death) with his continued work on the Origin of Species.

Keynes’ ultimate thesis is that Darwin’s private "life and his science were all of a piece," which he aptly portrays. The narrative left me with a greater appreciation of an iconic, and often misunderstood, man, someone who was both a brilliant scientist and a loving human being who made time in life for the things that matter most: family and friends.

Ancient DNA, Modern Diseases


http://news.nationalgeographic.com/news/2008/10/081029-mummies-disease-evolution.html

A recent National Geographic article reports that German scientists have discovered the earliest known cases of malaria – about 3,500 years old, to be exact. The researchers, who studied bone tissue samples in more than 90 Egyptian mummies, believe their findings could enlarge the current understanding of how modern diseases mutate in response to drugs. They also hope that "strategies to prevent the introduction of new infectious diseases or the re-emergence of ancient ones" might result.

Frank Rühli, head of the Swiss Mummy Project at the University of Zurich, asserts the importance of these findings:

"If you go back in the past and see th[e] genetic fingerprint [of a disease], say a hundred years ago or a thousand years ago or ten thousand years ago, it helps you to assess how it might actually react in the future."

There is no effective vaccine for malaria, and millions of people die from the disease every year. For this reason, the article claims that the findings take on additional importance: “Ancient samples of a microorganism's genetic code can show what its DNA looked like before any of its known mutations developed. An antibiotic designed to target a disease-causing bacteria in its earliest stages could then potentially cure its modern variations.”

Researchers are also studying ancient strains of tuberculosis, a potentially fatal bacterial infection. In 2007, they unearthed a 500,000 year old fragment of a Homo erectus skull with lesions that suggest TB, and recently, researchers located two of the oldest cases of TB in early humans to date. The article can be found here: http://news.nationalgeographic.com/news/2007/12/071207-tb-evolution.html.



With many diseases gaining resistance to antibiotics, this research has many potential benefits.
