I have been wondering about this for so long. Do those haplogroup mutations usually only occur in ONE of the father's sperm cells? So you can have two brothers in the same family carrying two different Y haplogroups, even if they are biological brothers by blood, both paternally and maternally...

Recently thought of this wild hypothesis: although the cats(feline) and dogs(canine) we see today are two totally different species, there actually existed a common ancestor which both felines and canines descended from known as the Miacidae, or the Miacis, a small, weasel-like insect-eating...

In the USA, fundamentalist Christians and most people who consider themselves very religious tend to reject many biological facts (evolution of species, existence of genetic predispositions, genetics playing a major role in intelligence or temperament, etc.). I was wondering if this ignorance...

Have you ever felt annoyed by the fact that national holidays in your country are often religious holidays? In many European countries Epiphany, Good Friday, Easter Monday, Ascension Day, Whit Monday, Assumption, All Saints' Day, Christmas and/or St Stephens' Day (aka Boxing Day in the UK) are...

It's not just interesting from a biological point of view, but that discovery could increase the supply of usable blood available for transfusions. LiveScience: Gut Bacteria Enzyme Can Transform a Blood Cell's Type "The key to changing blood types may be in the gut. Enzymes made by bacteria...

I have found a series of educational videos on YouTube sponsored by various organisations around the world, including the Bill and Melinda Gates Foundation and the Australian Academy of Science. It is called Kurzgesagt, which is German for 'shortly said', but better translated as 'in a...

If this is true it is potentially a Nobel-winning discovery. BBC News: 'Memory transplant' achieved in snails "A team successfully transplanted memories by transferring a form of genetic information called RNA from one snail into another. The snails were trained to develop a defensive...

Introduction The human body hosts hundreds of billions of bacteria, a number that varies with the food we eat, how often we wash ourselves, brush our teeth, take antibiotics or drink alcohol or other antibacterials (ginger, garlic, turmeric), but generally exceeds the number of human cells, and...

An international team of scientists from the universities of Oxford in the UK and Leuven in Belgium reconstructed the history of the HIV pandemic using historical records and DNA samples of the virus dating back to the late 1950s. The origin of the pandemic can be traced back to the city of...

While analysing the mtDNA phylogeny, I noticed that most of the common, successful mitochondrial haplogroups were defined by a new mutation in the Coenzyme Q - cytochrome c reductase gene (MT-CYB) encoding the Cytochrome b protein, located between positions 14,747 and 15,887 in the mtDNA...
