Did Charles Darwin Delay in Publishing Origins of Species? 4 Charles Robert Darwin (1809-1882) began working on his theories of the Origins of Species in 1837; however his works were published more than twenty years after that. There is much speculation as to why it took so long to publish the groundbreaking book; some suggest that he was afraid to challenge the scientific community and upset the Church. After first positing his ideas regarding how species underwent a “natural selection” and could possibly adapt over time, the text provoked adverted reactions from his intellectual mentors, Charles Lyell and Sir John Herschel. Still, Darwin continued working on his theory; if he really was affected by the potential of a negative response to his ideas, some believe that it seems more plausible that he would have abandoned research completely. Throughout the period during which he was working on the Origins of Species, he published essays revealing his work in progress. Many now believe that Darwin did not delay publishing, but rather, took over two decades to complete his work. (Adaptado de http://www. suite101.com/greatthinkers/4.

Public Health Cholera tightens grip on Haiti by Declan Butler As cholera rampages through Haiti, some epidemiologists are warning that the country could face more than half a million cases over the coming year. “It’s spreading like wildfire,” says Andrew Camilli, a cholera researcher at Tufts University School of Medicine in Boston, Massachusetts. As the current Haitian population has never been exposed to cholera, they lack any immunity to the disease, which makes the toll even greater. Vaccination might have helped, but it was not an option in Haiti because of the vaccine’s scarcity and the logistical difficulties in getting it to people in time. (Adaptado de Nature, vol. 468, p. 483-484, 2010.) a) Qual é a expectativa dos epidemiologistas com relação à disseminação do cólera no Haiti?
