It is generally agreed that the dividing line of Biology is 10,000 years ago. The organisms living before 10,000 years ago are paleontological species, and those living after 10,000 years ago are neontological species. Fossils are the seeds of the earth 10,000 years ago that evolved in the outside circumstances. - 生物分界一般以一万年前为界限，一万年前的生物为古生物，一万年前以后的为现生生物。化石，是经过外界演变的一万年前的地球的种子。
