Scientists have uncovered 3.7-billion-year-old fossils in Greenland that have set a new record for the earliest-known evidence of life on Earth.
Ancient tectonic activity was trigger for ice ages
Continental shifting may have acted as a natural mechanism for extreme carbon sequestration.
Reduced oxygen during ice age sheds light on ‘missing’ carbon dioxide
Climate is not constant on Earth. Consider ice ages coming and going as an example.
Extinctions without a fossil trace?
Many species now perishing in Earth’s ongoing sixth mass extinction might vanish without leaving a fossil trace – and earlier extinctions may be underestimated as well, according to a study by three paleontologists published March 2, 2016 in Ecology Letters.
Meat eating accelerated face evolution
Eating raw meat and making stone tools may be behind the smaller teeth and faces of humans compared with their ancient relatives.
