Chapter 12: earth's evolution. what are the principal characteristics that make earth unique among the planets? click the card to flip 👆. as far as we know, earth is unique among planets in the fact that it hosts life. the planet's size, composition, and location all contribute to conditions that support life (or at least our kind of life).

The fossil record shows us when specific types of organisms appeared, went extinct, or changed. and, the fossil record shows us that there have been mass extinctions in earth’s past. a mass extinction is when many species die off around the same time. a diverse set of fossilized marine organisms. these organisms lived about 450 million years ago. All life on earth evolved from a common ancestor. biologists map how organisms are related by constructing phylogenetic trees. in other words, a “tree of life” can be constructed to illustrate when different organisms evolved and to show the relationships among different organisms, as shown in figure 12.2. notice that from a single point. Cenozoic, mesozoic, and paleozoic eras. laramide orogeny. sierra nevada and rocky mountains built during mesozoic era. cyanobacteria. blue green algae. stromatolites. fossilized marine algae (precambrian) cambrian explosion. life forms with hard parts, organisms diversified.

Figure 3.1.1 3.1. 1: all organisms are products of evolution via adaptations to their environment. (a) saguaro ( carnegiea gigantea) can soak up 750 liters of water in a single rain storm, enabling these cacti to survive the dry conditions of the sonoran desert in mexico and the southwestern united states. Another piece of evidence of evolution is the convergence of form in organisms that share similar environments. for example, species of unrelated animals, such as the arctic fox and ptarmigan (a bird), living in the arctic region have temporary white coverings during winter to blend with the snow and ice (figure 11.12). the similarity occurs.
