As such, it seems as though twinning is at best something of an evolutionary accident, and to some degree it surprising that it has persisted in our species. But University of Sheffield evolutionary biology Ian Richard thinks he figured out why twins have stuck around in humans. Since the 1950s, the UK Medical Research Council has provided medical care in rural Gambia, recording key data on 1,889 infants over 30 years. It provides a unique data set for populations without good access to medical care, and Richard says it reveals the solution to the twin mystery. According to the data, single babies born after their mother gave birth to twins were eight ounces heavier than average. In these circumstances, a heavier baby is pretty much always going to have a survival advantage and be more likely to survive infancy.

Internet political scientist stanley deutschland Evgeny Morozov has written a powerful essay in the New Republic about problems with the popular idea that the internet is an inherently democratizing force. The occasion for his ire is Steven Johnson new book, Future Perfect: The Case for Progress in a Networked Age.

Once those background conditions are factored in, it becomes far less obvious that increasing decentralization and participation is always desirable. Even Wikipedia tells us a more complex story about empowerment: yes, anyone can edit it, but not anyone can see their edits preserved for posterity. The latter depends, to a large extent, on the politics and the power struggles inside Wikipedia . . . Then Morozov goes on to question whether decentralization is really the best way to usher in social change after all: If one a
