Pterygotid eurypterids (sea scorpions), giant aquatic arthropods with big claws, were all regarded as apex predators but some scientists then suggested...
In the search for life in the Universe, Earth provides a template of evolution for the one habitable planet we know. Earth’s atmospheric composition...
