“What we have been able to do here is just to pull out ones that we know are present, and we have tested those in terms of their effects and it does suggest there is an impact. The next stage – and it is a big next stage - is trying to tease out what else is there and how those chemicals are interacting.” … [Read more...] about Study showing decline in dog fertility may have human implications

Dogs are twice as friendly to humankind as previously thought, suggests study
This revealed evidence of a separate origin which could not be detected in modern dogs because contact between prehistoric humans from east Asia and west Eurasia would have led to interbreeding, scrambling the genetic evidence. The Oxford scientists, however, could not make the direct link with a different wolf ancestor in the west because this proposed “ghost” population would have long since disappeared. … [Read more...] about Dogs are twice as friendly to humankind as previously thought, suggests study

Origins of sign language revealed: Scientists claim all signing variations around the world evolved from just FIVE European sources
Justin Power, a PhD student at the University of Texas in the US and first author on the study, said: 'While the evolution of spoken languages has been studied for more than 200 years, research on sign language evolution is still in its infancy. … [Read more...] about Origins of sign language revealed: Scientists claim all signing variations around the world evolved from just FIVE European sources
World’s oldest recorded meteorite impact: 43-mile wide crater in Western Australia was created by an asteroid strike 2.229 BILLION years ago
‘Now we know the Yarrabubba crater was made right at the end of what’s commonly referred to as the early Snowball Earth – a time when the atmosphere and oceans were evolving and becoming more oxygenated and when rocks deposited on many continents recorded glacial conditions,’ said Professor Kirkland. … [Read more...] about World’s oldest recorded meteorite impact: 43-mile wide crater in Western Australia was created by an asteroid strike 2.229 BILLION years ago
