To all:Calling all MEN: Are you ready for some RIBBING? Men were fooling the gentler gender that they came out of Man's ribs. The tables are turned. A little RIBBING OF MALES is in order. Scientists say that the Male Y chromosome is Undergoing OBSOLESCENCE. Man, we got a big problem. One day the gentler Gender won't need us. All that macho image has come to naught. Pitiful. Just remember the good times, when it all comes to an end and the ladies have won out Original article: Four Evolutionary Strata on the Human X Chromosome Bruce T. Lahn and David C. Page Science Oct 29 1999: 964-967. Read the followingdeccanchronicleonline.com A similar article appeared in NY Times on the same subject a few days ago. Genetic truth: Ladies first and gentlemen later Washington: Females evolved first and males much later from the mutation of female genes, with early life forms not needing the male for reproduction, according to a study published in the journal Science. The chromosome which makes males different from females first dawned 300 million years ago when the Y chromosome diverged from the X chromosome, said the study by David Page of the Massachusetts Institute of Technology and Bruce Lahn of the University of Chicago.Females have two copies of the X chromosome. Males have only one X The other is Y. Page and Lahn think the Y-chromosome somehow evolved from the X chromosome and the arrival of the first chromosomal males may have been a sporadic affair. They took a pair of X-Y chromosomes and looked at them as if they were fossils, comparing the genes on each and the number of mutations and used the differences to ?count back? to arrive at a rough estimate of which they were last alike. The DNA ?clock? of the chromosomes seemed to show that it took four big ?jumps? in evolutionary history to deliver a male, they said. The research results have punched a big hole in many theories on human evolution, including the Christian one. God, according to the Bible, created Adam as the ruler of his creations. Seeing his dearest creation suffering from being alone, God decided to create a partner for him. While Adam was asleep, God removed a rib from him and with it created Eve, according to the Bible.One of the most technologically challenging goals of the Human Genome Project remains the complete sequencing of the human genome within the projected 15 years. In the past 5 years, significant progress has been made toward developing the capability for large-scale DNA sequencing. When the genome project began, the longest DNA sequence obtained was the 250,000-bp cytomegalovirus sequence, which took several years to complete. Now, several laboratories have each generated at least 1 Mb; some have determined more than 10 Mb of DNA sequence, mostly from model organisms. The longest contiguous human sequence is 685 kb from the human T-cell Beta receptor locus, a chromosomal region involved in immune responses.
