WebOne led to the mosses of today; the other led to the fern, pine, and rose. Since that speciation event, both lineages have had an equal amount of time to evolve. So, although mosses branch off early on the tree of life and share many features with the ancestor of all land plants, living moss species are not ancestral to other land plants. WebSep 22, 2024 · OpenStax. All life on Earth evolved from a common ancestor. Biologists map how organisms are related by constructing phylogenetic trees.

WebThis pattern repeats as one goes through the phylogenetic tree of life: A change in an organism’s genetic makeup leads to a new trait which becomes prevalent in the group. Many organisms descend from this point and have this trait. New variations continue to arise: some are adaptive and persist, leading to new traits.
