Give an example of a factor that constrains the evolution of
animal body plans
Step by step
Solved in 4 steps
- Using the following terms, explain what classifications and groups humans fall into, from the most general to the most specific: symmetry, germ layers, coelom, embryological development.Describe how body plans provide useful information yet should be interpreted cautiously as evidence of evolutionary relationships.Suggest and support a hypothesis for the view that segmentation evolved in three different animal clades.
- find a pari of examples of homoplastic structures and think about the benefit that this similarity may confer on the organisms involved (these might not all be animals).Given the sources of evidence, explain precisely how it supports evolution. C. Homologous StructureThe word invertebrate is so broad that it describes 95 percent of all living animal species. Do you think the term invertebrate is too broad to be useful to scientists? Give reasons to support your answer.
- Cave paintings often depict various animals and other natural elements. What insights do you think can be drawn about the relationship between early humans and their environments? Minimum of 1 sentence.True or False: The presence of vestigial structures in humans (such as tailbones) provides support for an evolutionary hypothesisMorphological analogs are structures having similar functions but different origins. For example, the wing of an airplane and a wing of a bird are analogous but certainly have different origins. Name and explain the comparisons of THREE ideas that humans have borrowed from plants and animals to use in building structures and making materials.
- Discuss how Homo erectus might have differed fromHomo habilis.Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning.Write briefly about the "hobbit" species of hominin. What are the theories about its evolution? What was the species like? When and where did it exist? (Homo floresiensis)
