The Evolution of the Stickleback Fish. Watch the ~15 minute video, Making of the Fittest: Evolution of the Stickleback Fish (https://youtu.be/Pv4Ca-f4W9Q) and the 1 minute video “Stickleback Fish Environment” (https://youtu.be/IRqLy3Oz-oM), both from the Howard Hughes Medical Institute. Answer the questions that follow: True or False? Having pelvic spines is always advantageous to a stickleback. In one sentence, explain your answer. True or False? Dramatic changes in traits, such as the loss of limbs, can occur through mutations affecting a single gene. Provide evidence for your answer. Below is a simplified schematic representation of some of the genetic elements involved in the regulation of Pitx1 gene expression (from HHMI BioInteractive). The large grey rectangle represents the protein-coding region of the Pitx1 The smaller rectangles to the left (b and c) are regulatory switches (networks of regulatory genes); each one allows a specific binding protein to interact with it and…
Photosynthetic sun-basking shark: They grow to about 4 m long, are grey or brown bodied, with all of their fins being green. Their green fins have chlorophyll, so that they can convert sunlight to energy. Has a very tall dorsal fin and long upper caudal fin because of it. They still have gills but have developed the ability to close their gills so that they can “bask” on the surface of the water for up to 10 minutes without suffocating. They still consume small fish for nutrients as well. Decide what Kingdom and Phylum these organisms would fall under and explain your reasoning. If you feel that a new Kingdom and/or Phylum needs to be created for this organism, explain why, and list basic characteristics of your new Kingdom and/or Phylum.

Ungulates Ungulates, such as deer, reindeer, and elk, are hoofed mammals. These animals have keen hearing, clear vision, supple, well-conditioned muscles, and razor sharp reflexes. The evolution of the four-chambered stomach in ungulates developed as a result of a need to eat quickly in the open and chew later in the safety of cover. This process is called ruminating or "chewing the cud." In other words, ungulates regurgitate and then re- chew their food. Which of the following would be considered a physiological adaptation of ungulates? A) their four-chambered stomach B) their long legs, which help them outrun predators C) their ability to stand perfectly still, which helps them avoid predators D) their ability to hibernate to avoid cold winters
Which of the following not only increases surface area for nutrient absorption, but also slows down passage of food through the digestive system to allow for a longer time for absorption? the glomerulus the endostyle the amphibian typhlosole the spiral valve the columella O the pneumatic duct

Neoteny Some salamanders exhibit neoteny, becoming sexually mature while still retaining some larval characteristics. In some species, the neotenic characteristics have become a permanent state of the species (obligate neoteny = paedogenesis; both are called paedomorphic conditions). These have lost the ability to undergo complete metamorphosis (hellbender, amphiuma, and mudpuppy). In others, the animal does not undergo complete metamorphosis in nature, but can be induced to do so in the lab. An example of this is the Mexican axolotl (Ambystoma mexicanum), a large gilled salamander found in Mexico. In some species of salamanders, members of a population exhibit neoteny only when they are under stressful environmental conditions (such as crowding, scarce food, low concentrations of trace elements). This is called facultative neoteny. Tiger Salamanders (Ambvstoma tigrinum) frequently do this, but local populations of marbled salamanders show a tendency toward neoteny in Virginia.…
