Textbook Question
Chapter 13, Problem 14TYK

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
Based on the anatomical evidence from the photos below, create a claim about which modern organism is most closely related, evolutionarily, to the Megalodon. Provide reasoning to validate the evidence you chose to develop your claim.
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...arrow_forwardGive an example of an animal that has evolved through time such as birds, insects and others. How has this certain animal evolved? You may draw the evolution or simply explain. Thanks so much!arrow_forwardBased on phylogeny and history of evolution, do new anatomical features such as lungs (amphibians) arise de novo or came from pre-existing structures of their ancestors (like gills of fish)?

- 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_forwardPakicetus 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_forward
- Then answer the following questions: 1. Describe one characteristic you see in organism 3 which might have had an advantage over organism 2. 2. How might these fossils provide evidence for evolution?arrow_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.

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_forward
- The human esophagus and trachea share a passage leading from the mouth and nasal passages, which can cause problems. After reviewing vertebrate evolution in chapter 34, explain the evolutionary basis for this "imperfect" anatomy.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_forwardThe number and location of bones within fossilized vertebrate skeletons are similar to those in living vertebrates. Most biologists explain this fact by saying that extinct and modern vertebrates had similar needs had different genes both struggled for existence both share a common ancestor 1 3 4 Nextarrow_forward
