General Science 3320 Mastering Bio Review for final exam Roughly 1 8 million species have been described, although most scientists think there could be as many as 50 million species or more currently living on Earth However, in the video, Craig Venter seems more interested in the total number of discovered genes (he gives a total number of 20 million genes in the video) than the total number of

Is the number of species on earth increasing or decreasing . . . It takes about 24 splits to generate more than 10 7 lineages, giving an average of one every 25 million years for 600 million years, so there is no difficulty about achieving the current number of lineages in the Earth's biodiversity over time simply by splitting lineages However, it is unlikely that the present biodiversity on Earth was
