38.3 percent of the Ainu in Hokkaido are on welfare, compared with the local average of 24.6 percent
The trappings of modern anthropology
In 1965, the average man spent 42 hours a week working at the office or the factory; throw in coffee breaks, lunch breaks, and commuting time, and you're up to 51 hours. Today, instead of spending 42 and 51 hours, he spends 36 and 40. What's he doing with all that extra time? He spends a little on shopping, a little on housework, and a lot on watching TV, reading the newspaper, going to parties, relaxing, going to bars, playing golf, surfing the Web, visiting friends, and having sex. Overall, depending on exactly what you count, he's got an extra six to eight hours a week of leisure—call it the equivalent of nine extra weeks of vacation per year.
For women, time spent on the job is up from 17 hours a week to 24. With breaks and commuting thrown in, it's up from 20 hours to 26. But time spent on household chores is down from 35 hours a week to 22, for a net leisure gain of four to six hours. Call it five extra vacation weeks.
New methods may offer more accurate family tree of humanity.
The lead author is Rolando Gonzalez-Jose, from the Patagonian National Centre at Puerto Madryn, Argentina. It seems like the thesis of this paper is that facial traits do not appear out of the blue but result from continuous change. Ahh, sounds like a punctuated equilibrium debate. He argues that, specimen that have relatively minor changes in features as compared to others should not be automatically held up as representing a new species. Well, no duh.
In order to establish this, Gonzalez-Jose used a new analytical approach on 3D images of 17 hominid species, with a gorilla, chimp and modern human thrown in. The approach focused in on measuring the similarities and differences on a particular set of fundamental yet long-term changes in skull shape. Using computational methods, the skulls were compared on four variables,
Organizing the outcome of the measurements into a phylogenetic tree, reportedly reveals a clearer view on the evolutionary history of humans and their ancestors.
