TV Host’s Comments on Human Evolution Draw Fire

admin cxfhhv , , , , , , ,

first_imgHave humans stopped evolving? That question has been getting some rare media and blog attention this week ever since David Attenborough, the 87-year-old British naturalist and broadcaster, declared: “I think that we’ve stopped evolving.”In an interview published this week in the magazine Radio Times, the influential Attenborough, host of numerous television documentaries on natural science, held forth on a number of topics. At one point, he explained that so many more babies survive childbirth now that natural selection, as proposed by Charles Darwin, cannot act on humans to favor infants with traits that are beneficial today or to weed out those with adaptations that impair survival. “We stopped natural selection as soon as we started being able to rear 95–99 per cent of our babies that are born. We are the only species to have put a halt to natural selection, of its own free will, as it were,” he said.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Attenborough’s comments are getting attention (see here and here, for instance).But his view doesn’t reflect scientific consensus. “Humans are most certainly still evolving, just not necessarily in ways we might expect,” wrote Catherine Woods of the Center for Neural Science at New York University in New York City in May in Science.For example, millions of people in developing countries continue to live in poverty and to suffer from infectious diseases. Under these conditions, natural selection may be favoring genes that confer resistance to disease, such as AIDS and malaria, or enhance reproductive fitness in other ways, researchers said in a report in Science. “As long as some people die before reproducing or reaching reproductive age, selection is likely to be acting,” geneticist Chris Tyler-Smith of the Wellcome Trust Sanger Institute near Cambridge, U.K., told Science in 2005. And since that time, researchers have discovered a spate of human genes that evolution has strongly favored recently, such as mutations that help highland Tibetans survive at high altitude, Yupik Eskimos to stay warm efficiently, Europeans to thrive on cereal grains, and East Asians avoid alcoholism.last_img

No suspects in cow shootings north of Fort St. John

first_imgOne farmer reported just before 4 p.m. on the 23rd that one of his cows had been shot and killed, and an hour later another farmer nearby called police to say he had found three of his cows killed and another eight wounded. One of those cows was pregnant, and has since had to be put down. “This is a tragic event on many different levels,” says Corporal Jodi Shelkie. “These cows have a value to their owners. As well, three of the cows had calves that now have to be nursed by a surrogate cow and it is not certain if they will survive. The senseless death and wounding of any animal is disturbing.” At this point there is no suspect in the shootings, as neither farmer was in the vicinity at the time. Anyone with information is asked to call RCMP at 250-787-7100 or Crime Stoppers at 1-800-222-8477.- Advertisement –last_img
