Fossil Record and Embryology Quick Check:
Q: Which statement best describes the importance of wisdom teeth to human evolution?
A: They are vestigial structures that once performed an important function for human ancestors.
Q: Which statement is true?
A: Imprints of leaves or footprints in sedimentary rock are fossils.
Q: This diagram shows the relative positions of human ancestors in rock layers. Which statement about these fossils is supported by the evidence in the diagram?
A: erectus is the most recent ancestor to modern humans.
Q: Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
A: The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
Q: 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: a close evolutionary connection between humans and many other mammals
1. They are vestigial structures that once performed an important function for human ancestors.
2. Imprints of leaves or footprints in sedimentary rock are fossils.
3. erectus is the most recent ancestor to modern humans.
4. The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
5. a close evolutionary connection between humans and many other mammals
Heyyoo is correct :]
all correct
everyone is correct
A: It indicates that humans enjoy the perks of being part of the mammal club, like having tails in our earlier stages and producing milk. I guess you could say we're the "Mam-mazing" species!
To answer these questions, we need to understand the concepts of the fossil record and embryology. Let's break down each question and explore how to arrive at the correct answer.
Q: Which statement best describes the importance of wisdom teeth to human evolution?
A: They are vestigial structures that once performed an important function for human ancestors.
To answer this question, we need to understand the concept of vestigial structures and their significance in human evolution. Wisdom teeth are considered vestigial structures because they no longer serve a crucial function in modern humans. However, they were likely essential for human ancestors who had a different diet or jaw structure. Therefore, the correct answer is that wisdom teeth are vestigial structures that once performed an important function for human ancestors.
Q: Which statement is true?
A: Imprints of leaves or footprints in sedimentary rock are fossils.
To determine the correct answer, we need to know what constitutes a fossil. Fossils are preserved evidence of past life, which can include imprints of leaves or footprints in sedimentary rock. These imprints provide valuable information about ancient organisms and their environment. Therefore, the correct statement is that imprints of leaves or footprints in sedimentary rock are fossils.
Q: This diagram shows the relative positions of human ancestors in rock layers. Which statement about these fossils is supported by the evidence in the diagram?
A: erectus is the most recent ancestor to modern humans.
To identify the correct statement based on the diagram, we need to understand the concept of relative positions in rock layers. The fossil record shows that organisms found in deeper rock layers are older than those in more recent layers. In the given diagram, if erectus is depicted in a higher position (closer to the top), it suggests that erectus lived more recently in geological terms and is therefore the most recent ancestor to modern humans.
Q: Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
A: The early stages of embryo development in fish and humans look strikingly similar, while insects develop very differently compared to both fish and humans.
To determine the supporting evidence for humans being more evolutionarily related to fish than insects, we need to consider the concept of embryology and comparative development. Embryology studies the development of organisms from fertilization to birth, looking for similarities and differences among species. In this case, if the early stages of embryo development in fish and humans show striking similarities, while insects develop differently from both fish and humans, it suggests a closer evolutionary connection between humans and fish.
Q: 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: A close evolutionary connection between humans and many other mammals.
To interpret the implications of human embryos having tails and other mammalian characteristics, we need to understand the concept of evolutionary connections. The presence of shared characteristics, such as tails, hair, and milk production, among humans and several other mammalian species, indicates a close evolutionary connection. These shared features suggest a common ancestor and evolutionary history linking humans to many other mammals.
By understanding the concepts of the fossil record and embryology, we can approach these questions and arrive at the correct answers by applying our knowledge of these subjects.
