Chapter 18, Problem 15TYU
EVOLUTION LINK Although most salamanders have four legs, a few species that live in shallow water lack hind limbs and have extremely tiny forelimbs (see photograph). Develop a hypothesis to explain how limbless salamanders came about according to Darwin’s mechanism of evolution by natural selection. How could you test your hypothesis?
The narrow-striped dwarf siren (Pseudobranchus striatus axanthus) is an aquatic salamander that resembles an eel. It is native to Florida.

How could you test your hypothesis?
Consider the following statement. Is it true or false? Why? Please justify your answer explaining the evolutionary process
that took place using terms and concepts discussed in our lectures.
Individual snakes had to evolve and adjust their mouth size to adapt.
Human embryos have tails which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and
mammals Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
a close evolutionary connection between humans and many other mammals
a very distant evolutionary connection between humans and many other mammals
a very distant evolutionary connection between humans and many other reptiles
a close evolutionary connection between humans and many other reptiles

- From this lab, one might conclude that certain trends can be detected, trends from ancestral features (those that arose early in the evolution of animals) to more derived traits (those that arose later). However, animals with ancestral characteristics still successfully exist on Earth today. Why is this so? Why have the animals with derived traits not completely replaced the ones with ancestral traits? Use examples from the lab to illustrate your answer. examples cephalochordata jawless fishes jawed fishes tetrapods ratarrow_forwardHow would you apply this in a Lamarckian explanation? Tiger Moths (Bertholdia trigona) produce high pitched ultrasonic clicking (at a rate of 4500 clicks/sec) when they hear the echolocation calls of bats (bats eat moths). As a result, the bat's sonar is jammed and the Tiger Moth escapes without being caught, killed, and eaten. Please use your knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths. Please use your Knowledge of Evolution by Natural Selection to explain the process by which this remarkable anti-predator defense evolved in Tiger Moths.arrow_forwardIt is believed that the coelacanths and lungfish represent a crucial link between other fishes and tetrapods. What is the major feature in these fish in support of this hypothesis? O Like amphibians, they are tied to the water for reproduction. Their fins have skeletal and muscular structures similar to amphibian limbs. They have lungs and are able to breathe air when water is scarce. O They have highly evolved nervous and circulatory systems. They enter a hibernative stage when food is scarce, as many tetrapods do.arrow_forward
- Flying fish use large pectoral fins to glide in air to escape predators. Explain how Lamarck and Darwin each might account for the origin of these large pectoral fins and the ability to glide.arrow_forwarda- Tiktaalik is a fish that lived 375 million years ago that grew to three metres long and had aquatic features mixed with others more suited to life on land. The fossils of five Tiktaalik specimens reveal that the animals had a large, robust pelvic girdle, a prominent hip joint, and long hind fins. The powerful fins could have propelled the beast in the water, but also helped it walk on riverbeds, or scramble around on mudflats. It is believed that Tiktaalik evolved into four-legged land animals. The scientists have yet to find a Tiktaalik hind fin bone, or any remains that might shed light on the origins of toes. A picture of Tiktaalik is available at https://www.npr.org/2010/07/05/127937070/the-human-edge-finding-our-inner-fish Describe how Darwin would explain that evolution of hind legs (of land animals) actually began as enhanced hind fins (of Tiktaalik), referring to his relevant observations and inferences (History of Evolutionary Thought). Indicate where the observations and…arrow_forwardThe presence of tiny hairs, called setae, on the toe pads of some geckos is associated with the ability to adhere to smooth surfaces. This ability allows geckos to climb in areas where many predators cannot. Scientists studying the evolution of setae have identified three closely related species of gecko, only one of which can adhere to smooth surfaces.. A model of the evolutionary relatedness between these species is represented in the figure. G. humeralis 1 Can adhere OG. concinnatus O Cannot adhere O G. antillensis Which of the following statements is an accurate description of the evolutionary relationships shown in the model?

- There are many common misconceptions about evolution. Which is TRUE about whale evolution? Early ancestors of whales evolved blowholes because they needed to breathe in the water. Whales are descended from monkeys. Modern whales are perfectly adapted to an aquatic lifestyle. The traits found in whales represent modifications of previous features that were found in their ancestors. Baleen whales evolved their distinctive filter feeding structure by chance.arrow_forwardIn 1928 Walter Garstang hypothesized that tunicates resemble the ancestral stock of the vertebrates. Explain this hypothesis and evaluate its validity with recent phylogenetic, fossil, and developmental data.arrow_forwardThe phylum Chordata only contains vertebrate species.

Both reptiles and birds live exclusively on land. Both reptiles and birds lay eggs. Both reptiles and birds breath through lungs.

- According to Lamarck’s theory of evolution, organisms change during their lifetime to survive then pass these changes to their offspring. What supports the hypothesis of Lamarck? a. Webbed toes of ducks to quickly move through the water, retractile claws of carnivorous mammals to catch the prey, millipede producing awful smell for self-defense and evolution of short-necked to long-necked giraffe b.
