The issue is that, when we build a tree, we are reconstructing that evolutionary history from incomplete and sometimes imperfect data. Figure 2. Discuss evolutionary relationships in pinnipeds. found that native lizards adapted to higher perches when a related species invaded their habitat. The basic principle of such a comparison is similar to what we went through above: there's an ancestral form of the DNA or protein sequence, and changes may have occurred in it over evolutionary time.

For example, Jamaica only has four species of lizard, where as Cuba has all six species. After this event, already, What do the similarities among the forelimb bone arrangement of these diverse animals imply about their ancestry? A species may have a derived trait, but then lose that trait (revert back to the ancestral form) over the course of evolution. Other species will see the same thing and have the same A.) In other This process is called natural selection. If the population from one of the experimental islands were reintroduced on the original island, do For example, is the presence of lungs an ancestral trait, or is it a derived trait? For example, our most recent ancestor with chimps was Australopithecus afarensis. That is, we have to look at our species of interest such as A, B, C, D, and E and figure out which traits are ancestral and which are derived.
