Whether the pattern of rate of evolutionary changes over time intervals holds true for most characters. Introduction: The degree and rate of evolutionary changes vary in all organisms. For example: the rates of evolutionary change measured over short time intervals are often very high. However, rate of evolutionary changes that is measured over long time intervals are generally much lower.

Four Caribbean islands with similar environmental conditions have three different species of anole lizards with specific ecological morphotypes. Lizards Morphotypes Grass lizards Long tails Canopy lizards Large toe pads Twig lizards Short legs Researchers devised two phylogenetic trees to represent two different hypotheses about how the lizards may have evolved. The first hypothesis is that the different body types evolved repeatedly and independently of each island. The second suggests that each morphotype evolved once and spread to different islands. Which of the following statements best explains which type of data the researchers should use to test these two hypotheses, and which phylogenetic tree correctly shows the evolutionary relationships among anoles? Analyzing DNA samples from the anoles would likely show that phylogenetic tree B is correct since it is likely that each body type evolved once and spread to different islands. Analyzing the…

This phylogeny consists of two distinct genera of cat; one with one species (P. aliquam) and another of three species (the red box indicates their distance). The species have three main physical traits: coat colour, ear tufts and tail shape. At the ancestral nodes of the tree, it can be seen what the ancestor of these species looked like for these three traits. Each of these traits has undergone a different type of evolution. Choose one type of evolution and explain the mechanism that brought the given characteristics.

In the past, the evolutionary history of whales was represented by cladogram A, shown below. As you can see, whales were believed to be closely related to mesonychids, an extinct group of mammals that looked similar to wolves. Today, that cladogram has been revised, as shown in cladogram B. Which of the following statements best describes the reason for this change? A - Cladograms A and B are hypotheses that changed as new evidence became available.B - Cladogram B was revised to show a water-to-land pattern of evolution in groups of organisms.C - Cladogram B was altered to better include similarities in habitat as new information became available.D - Cladograms are organized today to show a much more simplified pattern like the one shown in cladogram B.
