The discovery of 2.4-million-year-old stone tools and butchered bones at a site in Algeria suggests our distant hominin relatives spread into the northern regions of Africa far earlier than archaeologists assumed. The find adds credence to the newly emerging suggestion that ancient hominins lived—and evolved—outside a supposed Garden of Eden in East Africa.
The European Union unveiled its long-term vision on combating climate change in a push for more ambitious action on the environment just days after U.S. President Donald Trump rejected his government’s warning on the economic costs of global warming.
The 28-nation bloc, responsible for 10 percent of global greenhouse-gas emissions, set a 2050 perspective to help give direction to member states, companies and citizens to anticipate costs in fighting temperature increases. The EU’s updated strategy comes a week before representatives from almost 200 countries are due to meet in Poland for an annual conference on addressing climate change.
Recent cold snap see’s a higher number than usual of critically endangered turtles stranded during their migration south.
A dead sperm whale that washed ashore in a national park in Indonesia had nearly 6kg (13 lbs) of plastic waste in its stomach, park officials say.
A grim U.S. government assessment of global warming’s economic impacts gives a whole new meaning to Black Friday.
What’s remarkable about the new discovery, says Brusatte, is that this very old cousin of mammals had evolved similar features—a huge size and column-like limbs held under the body—as true mammals would, albeit many tens of millions of years later.
Scientists say we’re all eukaryotes: Plants, animals, fungi, and tiny multicelled organisms called protists are the four kingdoms of life, which encompass everything living that we’ve found on Earth.
But a new discovery from Dalhousie University in Nova Scotia, published in Nature, claims to have discovered a fifth kingdom of life—a new kind of eukaryote. The paper describes two organisms, one newly unearthed in Nova Scotia and one discovered in 1988, which upon DNA analysis are more distinct from anything else than previously thought.
Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. Better healthcare disrupts a key driving force of evolution by keeping some people alive longer, making them more likely to pass on their genes. But if we look at the rate of our DNA’s evolution, we can see that human evolution hasn’t stopped – it may even be happening faster than before.
This is the first study to measure the physiological effects of exposure to crude oil on marine life’s olfactory systems. The results concluded that when exposed to crude oil, stingrays’ had significantly reduced olfactory functions.
