Textbook Question
Chapter 13, Problem 14TYK
SCIENTIFIC THINKING Cetaceans are fully aquatic mammals that evolved from terrestrial ancestors. Gather information about the respiratory system of cetaceans and describe how it illustrates the statement made in Module 13.18 that “Evolution is limited by historical constraints.”

The human embryo and the embryos of other animals with backbones have gill slits. According to the modern
evolutionary theory, this best supports the idea:
Mark only one oval.
That fish are our closest relatives
All embryos breathe through their gills
All animals with backbones are related by common ancestry
All organisms have gill slits at an early stage in their development
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.
Pakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modern whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull.
According to this information, the most likely conclusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus...

- How 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.

- A group of scientists examine the skeletal evidence below. Gibbon Orangutan Chimpanzee Gorilla Human What conclusion can be drawn from the diagram to support the theory of evolution? Man evolved from gorillas which evolved from chimpanzees. O Gibbons are most closely related to man because of similarities in their skeletal structure. O Orangutans have a larger jaw size than chimpanzees, allowing them to have a more carnivorous diet. Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food. O O O Oarrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity:arrow_forwardThe fossil record shows that the first mammals evolved 220 million years ago.

- Pakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modem whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull. According to this information, the most likely concilusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus O evolved as whale ancestors lost their forward-placed nostrils through disuse. O is the ancestor of both Pakicetus and modern whales. O is not related to either Pakicetus or modern whales. O is a transitional form between Pakicetus and modern whales.arrow_forwardSome genetic studies suggest that the most recent common ancestor of Homo sapiens that lived outside of Africa spread from Africa about 50,000 years ago. Compare this date to the dates of the fossil record. Can both the genetic results and the dates ascribed to the fossils be correct? Explain and Justify.arrow_forwardAll vertebrate embryos have a tail and gill slits at some point during embryonic development. What does this suggest about vertebrates? These species evolved in similar environments. These species have the exact same DNA sequence. The embryos of these species require these structures to survive. These species share a common ancestor.arrow_forward
- Morphology - Comparative Anatomy More evidence for evolution is offered by comparing the anatomy, or body parts, of different organisms. Many animals have body parts that are similar in both structure and function called homologous structures. The forelimbs of animals like humans, whales, birds, and other creatures are strikingly similar even though the forelimbs are used for different purposes such as lifting objects, swimming, or flying. The different changes in the forelimbs are adaptations to the needs of the organisms. Darwin also observed that animals have structures that they do not use, which are called vestigial organs. These are structures that an organism has that do not have a function, though they may have had one in the past. In humans they include the appendix, the fused tail vertebrae, and Humerus wisdom teeth. Perhaps an environmental change made the organ unnecessary for survival, and the organ gradually becomes Radius Ulna Carpals nonfunctional. For instance, the…arrow_forwardCharles Darwin and Jean Baptide de Lamarck have different ideas of explaining evolution. Describe how each of them explained the evolution of long necks of giraffes.
