Give at least 3 examples of higher forms of life that are bilaterally symmetrical. Explain why they are bilaterally symmetrical.
Because many of the key mechanisms of evolution activate when sperm and
egg combine, volutionary change happens faster for organisms with short life
cycles (viruses, bacteria, fruit fly, yeast) compared to organisms with long life
cycles (humans, elephants, tortoises).
True
False
According to this picture of embryos (early developmental stages), which two organisms are most closely related?

- You are studying the evolution of species. After performing DNA analysis, he discovers a gene that is conserved from yeast to humans. In which cellular processes is this gene most like to be involved? Could this gene have evolved to confer some of the complex traits that we observe in modern animals, like multicellularity? Briefly explain.arrow_forwardA researcher studying the wing structures of bats, birds, and insects finds that while they all have wings, their underlying bone structures and development are different. The wings of these organisms are examples of: Homoplasy Homology Synapomorphy Apomorphyarrow_forwardNow, it is time to put together all the information you learned about the different kingdoms into one concept map. All terms must be included. You may create this concept map however you like. You may use pen and paper or you may choose to use a computer program/digital tool. Another option would be to use index cards to write the terms on them and then organize them on a flat surface and take a picture to submit when complete. This could be done with “sticky notes” on a wall too. There are lots of terms and you must consider how they will be organized together. Notice how, in the example above, the categories or ‘groupings’ that were not official scientific classifications (for example, simple invertebrates, worm-like invertebrates, complex invertebrates, joint-legged invertebrates, invertebrates, and vertebrates) do not have kingdom, phylum, or class in front of them. They are just classifications that scientists use to help them understand the living world. In your concept map, make…arrow_forward
- You are examining an organism you believe to be an animal. Which of the following would NOT support your hypothesis? O A The organism appears to be heterotrophic. O B The organism appears to be multicellular. O C The organism appears to be motile. O D The organism appears to have cell walls. O E All animals, including sponges, have development directed by Hox genes.arrow_forwardWhy do scientists consider vestigial structures evidence for evolution?arrow_forwardTo describe: The two general steps that are required for a new species to arise.arrow_forward
- What is Le Chatelier's Principle? Describe how this principle explains the reversal over evolutionary time of a cellular process of your choice. In the course of this explanation, use two sketches to completely describe how the cellular process ran before and after it was reversed by Le Chatelier’s principle, including 1. all inputs/where they come from 2. all outputs/where they go 3. what good the process does the cell.arrow_forwardDifferentiate analogous structures from homologous types. Identify which is which among the shark, pigeon and cat when you transition from each of the classes. For this, create a 4-column table with the following headings: (1) Structure, (2) Specimen a vs b, (3) Specimen b vs c, and (4) Specimen c vs a. For each cell, write either AS for analogous structures, or HS for homologous types. Note (not all structures encountered need to be here).arrow_forwardWHY DOES SCIENTIST CONSIDER VESTIGIAL STRUCTURES EVIDENCE FOR EVOLUTION?arrow_forward
- Why do scientists consider vestigial structures (like a human appendix) evidence for evolution?arrow_forwardDefine the following terms: -automorphies -symplesiomorphies -classification -natural hierarchy -evolutionarrow_forwardGiven homologous structures like a bird’s wing & whale’s flipper and analogous structures like a bird's wing & insect's wing, prove evolution.arrow_forward
