The problem with blue eyes

I was watching an old TV shows from the 70s and I realized that the majority, (five of eight) of the leading actors had blue eyes. It seemed a bit unusual and a quick look at some stats confirmed that it was. If you have ever wondered how many people have blue eyes in the world, you have come to the right place.

Oops, that wasn’t supposed to happen: genetic study unravels evolutionary theory

A study produced by two geneticists Mark Stoeckle from New York’s Rockefeller University and David Thaler from Switzerland’s University of Baler concluded that 90% of animals came into existence at the same time as humans and relatively recently. This conclusion seriously challenges the theory of evolution that requires millions of years for animals to slowly evolve, with man being the climax of the evolutionary cycle. In their study published in the Human Evolution journal, the two geneticists examined the “DNA barcodes” of 100,000 species of animals stored in GenBank, a genetic data base operated by the American government. Based on this study, the two concluded that animals appeared at the same time as humans about 100,000 to 200,000 years ago. Though there may be some dispute on the dating, their study nevertheless confirms the Biblical account that says humans and animals were created at the same time on the fifth day. In an interview with Christian Headlines, Ken Ham founder of the creationist organization Answers in Genesis suggested the age numbers were inflated by evolutionary …

Johns Hopkins study concludes there is no gay gene

Researchers at Johns Hopkins University recently released a study stating there was no conclusive evidence of a gene that causes a person to be gay, lesbian or transgender. People are not born with gay affections. This study runs contrary to what some are suggesting in recent years. The report was co-written by Johns Hopkins’ scholar in residence Lawrence Mayer who is also a statistics professor at Arizona State University and Paul McHugh a psychiatry professor at Johns Hopkins. Many consider the two men as leading scholars on mental health in America. Mayer has taught at over eight universities including Stanford and Princeton and McHugh served as chief psychiatrist at Johns Hopkins for 25 years and was also elected to the President’s council on bio ethics. In their report, entitled “Sexuality and Gender: Findings from the Biological, Psychological and Social Sciences” published in The New Atlantis, the two researchers surveyed over 200 studies done on the topic in a variety of fields. They cited studies of identical twins, particularly one conducted in 2010 by a team …

Study of identical twins shows homosexuality is not genetic

For the past several years, some have claimed same-sex leanings are genetic. This means people have no control over their desires and can’t change. However there has been one major problem with this theory namely identical twins. Identical twins have the same genetic make up, so if one twin was gay the other should automatically be gay as well, if it is based on genes. However, this is not the case and it was confirmed again in a recent study conducted by the University of California (UCLA). In this study, researchers looked at the the genetic make up of 27 identical twins where at least one twin was gay and ten sets where both were gay. The researchers concluded that environment, not genetics, determined if a person was gay or not. While we have our basic genes that determine our make up, there is another molecular layer of information called “epigenetics” that influences how we live. This layer has the ability to affect our genes. It is described as “molecular switches” that they believe turn …

Studies of identical twins reveal homosexuality is not genetic

According to Dr. Neil Whitehead, studies of identical twins are concluding homosexuality is not genetic.  Dr. Whitehead has a PhD in statistics and biochemistry. There are twin data-bases in a number of nations around the world containing records of thousands of twins. Since identical twins have the same DNA,  geneticists are using these repositories to study the impact of genetics. If same-sex attraction is genetic as some claim, then if one identical twin is homosexual, the other would be born that way as well. However, one of the revelations coming out of these studies is the realization homosexuality is not genetically based.
