2亿多年前,地球迎来了巨型恐龙的时代,体长十几米、体重数吨的恐龙随处可见。这样的情景会再次出现在地球上吗?科学家表示,如果全球变暖持续下去,蜥蜴可能进化成恐龙那样的巨型爬行动物,地球可能再次迎来“恐龙时代”。全球变暖对不少生物来说是一场噩梦,一些物种甚至有灭绝之虞。然而,美国古生物学家詹森·希德等人认为,有一类动物会在全球变暖的大背景下逐渐繁荣起来,它们是包括蜥蜴在内的冷血动物。 More than 200 million years ago, the Earth ushered in the era of giant dinosaurs, more than ten meters in length and weighing tons of dinosaurs everywhere. Will such a scenario reappear on Earth? Scientists say that if the lizard may evolve into a giant reptile like a dinosaur if global warming continues, the planet may once again usher in “dinosaur age.” Global warming is a nightmare for many creatures, and some species may even be extinct. However, the American paleontologist Jensen Hedde and others believe that a group of animals will gradually flourish in the context of global warming, including cold-blooded animals such as lizards.
