Draw a phylogenetic tree that has these 8 animals:
Human, Insect, Sponge, Jellyfish (jelly), Placoderm,
Cuttlefish, Coral, Sea Urchin (urchin). With these 8
characteristics: (to be mapped on your tree)
- Single-lens (camera) eye
-Metazoa
-Deuterostome development ('Deuterostome')
-Bilateral symmetry ('Bilateral")
- Innate immune system ('Innate')
- Eumetazoa
- Viviparous
- Determine a derived characteristic for Cnidaria
and map it on your tree
Pretend you order an Asian seafood dish. It has clams, fish, squid, snails and jellyfish. How many
different PHYLA are represented in your dish? (be sure to count phyla, not classes.)

- How can embryos help scientists understand evolution? Embryos go through various stages that suggest the animal’s evolutionary process. Embryos are frequently fossilized and illustrate change over time. Embryos provide evidence for which life forms existed at the same time. Embryos contain the code for all life on Earth.arrow_forwardRead the Guilty dentist information. Then use your understanding to answer the following questions What was the hypothesis?

Develop a DICHOTOMOUS KEY to the CLASSES of Phylum ECHINODERMATA: Class Asteroidea (specimen: Linkia (blue sea star)), Class Ophiuroidea (specimen: Ophiotrix (brittle star)), Class Echinoidea (specimen: Diadema (black sea urchin)), & Class Holothuroidea (specimen: Holothuria (sea cucumber)) 2. Develop a DICHOTOMOUS KEY to the CLASSES of Subphylum VERTEBRATA; Class Amphibia (specimen: Rhinella marina (toad)), Class Reptilia (specimen: Coura amboinensis (turtle), Hemidactylus (house lizard), Elaphe erythrura (snake)), Class Aves (specimen: Gallus gallus (chicken)), Class Mammalia (specimen: Homo sapiens (human))arrow_forward

However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.arrow_forward
