He has found a minimum of 45 different karyotypes an extremely high number. It s really bizarre to see this, says Mr Sites, explaining that the animals look exactly the same despite their different genetic structure. To collect samples, Mr Sites and his team must catch the liz- ards, which is no easy task given the animals quick, darting moves The researchers use one of two rather unscientific but effective methods noosing them with a small nylon lasso on the end of a a rubber band Once caught, many part of the lizard are sampled for analysis bark at the lab The bone marrow is flushed from the animals' legs and arms, and chromosomes from the marrow cells are fixed on miwell-aime- shooting Vlay 2, B3 196 1 Suspect in Jewel Theft Accused of Being Fugitive Has Experts Eye Spinal Friday, croscope slides Skeletal muscle the liver and kidney are frozen in liquid nitrogen for protein anlay sis. and the heart is frozen from D.NA analysis Mr Sites' interest in the project is answering one of the big questions about evolution How does speciation occur, that is, what are the mechanisms by which a population of animals becomes different enough form neighboring populations so that it is genetically isolated While chromosomal rearrangement may be one of the ways begins, it end when a single, novel karyotype becomes fixed in a population and prevents gene exchange with populations of different karyotypes This prevention of gene exchange occurs with the help of "hybrid zones, Mr. Sites explains When the geographic ranges of two -- n different chromosome races' meet, an area where the chromo-somall- y a different races breed narrow hybrid zone is usually formed Several conditions must be met for this type of speciation to occur First, the chromosomal rearrangement must be detrimental in that it creates reproductive problems for hybrid offspring If it is deleterious, a hybrid zone develops and gene flow between the two distinct populations is ly blocked. Second, the population must be small enough so that inbreeding is high. Third, there must be some mechanism that generates chromosomal rearrangements in appreciable numbers. tive from justice Two Salt Lake City women who al legediy harbored escapee Kelly Lafe Garner, 25 of Long Beach, Calif , fur three days, also were arraigned Thursday on second degree felony charges of obstructing justice Mr Garner remains at large He is considered armed and dangerous police have said A criminal complaint filed in 5th Circuit Court alleges that Gordon Kent Nelson, 28 address unavailable, was a fugitive from Colorado when police arrested him April 25 in a room at the Radisson Hotel, 161 W 600 South Bail was set at $100,000 Lakewood, Colo , police obtained an arrest warrant for Mr Nelson in connection with an aggravated robbery April 9 in that city, the complaint said Mr Garner is considered a suspect in the robbery in which three people were robbed of an emerald in a Lake-woohotel room, according to a report at the Salt Lake City Police Department. Meanwhile, Holly Michelle Holt. 19. and Kaye Christensen, 18, were arraigned before 5th Circuit Judge Maurice Jones on a charge of obstructing justice Judge Jones set a May 8 preliminary hearing on the charge, and the two women were returned to the county jail where they are being held on $10,000 bail. They are accused of hiding Mr Garner in their apartment at 1531 S. Green St. (640 East) after Mr. Garner slipped a lock in a police interrogation room about 10 30 p m. Apnl 25 and escaped from the Metropolitan Hall of Justice. Police searched the two womens apartment Monday and found a pair of handcuffs in a closet, allegedly the same ones he wore during his escape, a criminal complaint said. Police arrested Mr. Garner on April 25 m the Crossroads Plaza Shopping Center, 50 S. Main, when he allegedly tried to sell a diamond at two mall jewelry stores. He was a suspect in the switch of a d fjke diamond fur a real one tfum Sierra West Diamond 36 S Stale earli- er that day Takf-to the Metropolitan Hall of Justice for quest, or.mg on the cie he discussed the alleged Colorado rob bery and about a dozen more jewel thefts and rot beries in the San Diego area, accord, ng to a police report After about four hours he told detectives he had stayed at the Radisson Hotel and had discussed the other crimes to buy t,me fur Mr Nelson to get away Polite arrested Mr Nelson in the hotel room and were questioning him when Detective Don Bell found that Mr Garner had escaped Mr Garner later telephoned Detective Bell to apologize, the report said During the investigation, detec tives also found a note in Mr Garner s personal effects linking him to the alleged switch of a fake diamond for a real one that former professional and Brigham Young I'niversity football player Golden Hu hards was Selling A SaU Lake County Sheriff s Office Iietective Fred Baird recovered that jewel in a pawnshop Wednesday, he said According to a Sheriff s Office report Mr Richards had advertised in a newspaper to sell four diamonds Mr Garner allegedly telephoned him on April 21 and using an alias, attempted to schedule an appointment to see them Mr Richards invited him to a house to see the jewels that night Mr Garner allegedly came over -- nd looked at the diamonds and later scheduled another appointment to meet hirn in a hotel the next night, the report said Mr Richards and a brother then allegedly met Mr Garner on the sec-ond level of the Little America Hotel During a conversation there, the brothers became suspicious and left. A different man telephoned Mr Ric hards the next day to set up another appointment Before Mr Richards could say he wasn't interested, the man hung up Mr Richards waited for the man to appear that night, but neiiner Mr Garner nor the otner man of law enforcement to control Mr Ward said He said drug abuse, particularly among youth, is the mast dangerous ability it, problem facing America today, adding that the growing monster is destroying a rapidly increasing number of young lives before they have a chance to get started The distribution of illegal drugs has become a $100 billion industry in the United States with more than 100 tons of cocaine alone smuggled across the border last year, he noted. In Utah, he said, surveys indicate that 12 percent of the high school seniors have experimented with cocaine and 36 percent have used marijuana. Of the hard core drug users, he said, 16 percent are between the ages of 12 and 16 and 28 percent are between the ages of 17 and 25. One boy recently told me he was offered drugs at least twice a day at Bountiful High School," Mr. Ward said "My own daughter, an eighth grader at Clayton Middle School, came home the other day and said a classmate had been taken to the hospital for a drug overdose. Mr. Ward said drug abuse has become a problem "in every grade in every junior high and high school in , showed up Mr Richards called a friend to check the diamonds, and the friend told him that a diamond Mr Richards had once had appraised at $2,500 wasn't real, the report said Drug Abuse Called Public Enemy No. By Raul Roily Tribune Staff Writer "Public Finemy No 1 is on a collision course with the collective happiness of tTS citizens and will destroy the country unless a massive, conscious effort is made to derail its progress That was the message Thursday of U S Attorney for Utah Brent Ward, who told the Salt Lake Kiwams Club the biggest danger facing America is the eventual tolerance and acceptance of the use of illegal drugs "We made a terrible mistake in this country in the 1960s when we allowed it to be said that the use of illicit drugs was a victimless crime, Mr Ward said He added that the acceptance of the use of drugs by some of the most worshiped of the youth's role models like rock stars and athletes put the problem of drug abuse on a rocketing course that is moving it outside the ability of law enforcement to deal with it. "This isn't a sprint It's a marathon, he said of the fight against drug abuse Once the collective morality no longer expresses disgust (in the use of drugs) and it is eventually tolerated and accepted, it will be outside the J 1 the Salt Lake Valley He said drugs or drug pat aphernaha have been con- fiscated at "every elementary school in the valley " He said drug abuse has become "a $30 billion to $50 billion albatross around the neck of American busi- ness American Motors reported k lost 6 5 million man hours in sick ill- leave due to drug abuse-relateI ness." d ' ; " The reason drug abuse is the court- - try's "Public Enemy Number One Mr Ward said, is that for the first time, a law enforcement problem is outstripping law enforcement's abili- . ty to deal with it. ' He said the greatest threat to America is if the drug abuse problem becomes so common that citizens become disinterested, then tolerant, then accepting. The inability of law enforcement to control the consump- tion of alcohol during prohibition is an example of how the law can be defeated once an illegal practice becomes accepted by society, Mr. Ward warned "We need to stand up and say, Not in my school. Not in my neighborhood, Not in my family," Mr. Ward said ; i (gganfflflil) vs eductions arkdowns ercentaqeslotijepresensavmgs ricednerchandisejwiltiffective flntiLstoc nless otherwise. indicated Only 5.99 Mens poplin shorts, or boxe ReqT5T5(Fand $131 Big girls Great selection Gray, navy, khaki or red with piping trim.
