In biology a trait that arose in an ancestor
WebFeb 16, 2024 · A monophyletic group is a group of organisms that are all descended from a common ancestor. This means that all members of the group share a single ancestor, and their evolutionary histories have not diverged from that ancestor. In contrast, a polyphyletic group is one composed of organisms that do not all share a single ancestor. WebThe traits which are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity. …

WebJan 13, 2024 · The coccyx or the tailbone: Obviously, humans no longer have visible external tails, because the current version of humans do not need tails to live in trees as earlier human ancestors did. However, humans still have a coccyx or tailbone in their skeletons. In fetuses, any tail is absorbed during development. WebApr 9, 2024 · Eventually, environments change, and what was once a desirable, advantageous trait may become an undesirable trait and organisms may further evolve. Evolution may be convergent with similar traits evolving in multiple species or divergent with diverse traits evolving in multiple species that came from a common ancestor.
