...suggestion. Which is the same as last year's sure fire suggestion and the one the year before that: to wit, a sex manual. Now you may think these are prurient and dumb, or you might think they are useful. Either way, it makes a great joke under the tree...
...does every year. So many things happen during reading period, it seems, because there is no one around to complain; if a tree falls in the forest and there is no one there to hear it, is there noise? Has the tree fallen...
...scientists have resisted this vision of man's family tree, and have proposed that the African apes and man branched off on their separate paths much more recently. Their evidence is not ancient bones, but what the University of California's Vincent Sarich calls a "genetic clock." That timepiece is based on comparative studies, done since the early 1960s, of the blood proteins, immunology and DNA (the genetic molecule) of various mammals, including the primates. Out of this work scientists have been able to measure the degree of genetic kinship among different species. They have found, for example...
...using such genetic differences almost as if they were tree rings, Sarich and John Cronin have gone on at Berkeley to produce a chronology for the appearance of various creatures. Their research has provided hitherto unavailable biochemical support for the traditional idea that the Asian apes, the gibbons and orangutans, branched off from the common primate evolutionary tree much earlier than chimps, gorillas and man. But it also offers what Sarich and Cronin consider strong evidence that the split between man and African apes occurred only 4 million to 6 million years...
Kaplan says that in the 1960s he began noticing that his pupils were coming to New York from such far away places as Florida and California just to take his course. Still, his tree stayed in Brooklyn...
