Chickens are evolving faster than previously thought, according to new research that challenges ideas of when they were domesticated and may have implications for human migration.
The findings, published in journal Biology Letters, are based on a genetic analysis of a chicken population that can be traced back over 50 generations.
The international team of researchers sequenced 12 mitochondrial genomes – DNA generally thought to be passed down from the mother to their offspring – in a well-known population of White Plymouth Rock chickens.
Previous chicken research – March 2014 – has been used to gauge human events in history, notably that Christopher Columbus beat Polynesians to South America :: Read the full article »»»»

Scientists have made a long-awaited breakthrough in human cloning, by using human skin cells to create early-stage embryos. The breakthrough marks the first time human stem cells have been produced via nuclear transfer and follows several unsuccessful attempts by research groups worldwide
In what is being described as a “significant milestone” for medicine, the team from Oregon Health and Science University successfully used a technique which utilised a human skin cell and a woman’s egg to produce an embryo which was a genetic copy of the original skin cell.
The resulting embryos were then used as a source of stem cells, which can be used to create specialised tissue cells for transplant operations. However scientists say they do not think the technique could be used to clone humans for reproductive purposes :: Read the full article »»»»
