美国一个研究小组对地球上的生命起源进行了长时间的研究后得出结论称,地球上最原始的生物物种是海绵生物。据美国马萨诸塞州大学的科学家所提供的初步研究资料显示,海绵生物成功地进化发生在距今约5.4亿年前,而此前的资料显示,可将水下生物最早出现的时间推算至寒武纪大爆发时期。
A long study by a U.S. team on the origins of life on Earth concluded that the most primitive species on Earth is a sponge. According to preliminary research data provided by scientists at the University of Massachusetts at the University of Massachusetts in the United States, the success of sponge evolution occurred about 540 million years ago, but previous data showed that the earliest occurrence of underwater organisms could be estimated to Cambrian The eruption time.
