A cell in prophase I of meiosis has twice as much DNA as each of the daughter cells following cytokinesis of meiosis II.
Meiosis is reduction cell division through which gametes (eggs or sperm cells) are formed. Reduction division means that four haploid cells (n) are produced from a single diploid cell (2n). The number of chromosomes is reduced by half during meiosis but during fertilization are returned to the full numer, when the two gametes fuse.
They leave no record of their existence because it's rare that fossils form. You need the right conditions in which the animal's remains are covered in silt, dirt, and rock layers in order for a fossil to form and therefore preserve the animal's remains in rocks. Otherwise, the animal's remains will be eaten by other animals or eventually rot away.
