Assignment: Distinguishing Phyla Exploration
In this exploration, you will look carefully at pictures of animals and consider some physical characteristics that scientists use to classify each organism. For each characteristic, it may be difficult to reach an accurate conclusion using only a picture. Actual classification relies on far more characteristics than are considered in this exploration, but by comparing your results, you can begin to get an idea of how each kind of organism is similar to and different from the others.
Examine the pictures of the organisms in the lesson. Then fill in the Observations Table using the pictures as references. In each case, use your best judgment based on what you can see in the picture.
Observations Table
Representative organism
Type of symmetry (Radial, Bilateral, or None)
Type of skeleton (ENdoskeleton, EXoskeleton, or None)
Type of appendages (Jointed, Not Jointed, or Absent)
Segmentation (Present or Absent)
Sponges
Cnidarians
Roundworms
Annelids
Mollusks
Arthropods
Echinoderms
Vertebrates
Questions

Which grouping has the least complex body plan? If you were on a research expedition in the kingdom of Tonga, a coral atoll in the South Pacific, would you find these organisms?

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related
