英国科学家新近宜称,他们在英国南部业已存在亿年以上的粘性岩石中,找到了地球上最古老的花卉。 开花或被子植物在过去的6500万年中一直是地球上的主要植物。然而古植物学家们对一些基础问题仍有争论,比如花卉的原始物及从何进化而来。有人曾认为最早的开花植物应是类似木兰花的大型灌木。但最近发表在《白垩纪研究》杂志上的克里斯·希尔博士的新发现,却支持六年前英国科学家所提出的植物从小开始的假设。 1990年,来自美国耶鲁大学的泰勒等人,从澳大利亚发
British scientists recently said they found the southern part of the United Kingdom has more than billion years of sticky rock, found the oldest flower on earth. Flowering or angiosperm has been the main plant on Earth for the past 65 million years. However, ancient botanists still argue on some basic issues, such as the original of flowers and their evolution. Someone once thought that the earliest flowering plant should be a large shrub like magnolia. However, the recent discovery by Dr. Chris Hill in the Cretaceous Research magazine supports the hypothesis that British scientists put forward plants six years ago. In 1990, Taylor and others from Yale University in the United States made their deliveries from Australia
