Textbook Question
Chapter 13, Problem 11TYK
In the early 1800s, French naturalist Jean Baptiste Lamarck suggested that the best explanation for the relationship of fossils to current organisms is that life evolves. He proposed that by using or not using its body parts, an individual may change its traits and then pass those changes on to its offspring. He suggested, for instance, that the ancestors of the giraffe had lengthened their necks by stretching higher and higher into the trees to reach leaves. Evaluate Lamarck’s hypotheses from the perspective of present-day scientific knowledge.

In 1822, an Arkansas farmer discovered a fossil when a hill collapsed on his property. The farmer sent the bones to the Philadelphia society to be reviewed by scientists where it was determined that the bones were from a whale. Through research, the scientists discovered whales have a vestigial structure that includes a pelvic girdle and hind limbs.
Which evidence best supports the theory that organisms, such as whales, have common ancestry and have evolved? Select all that apply.
Group of answer choices
A/Ostriches and emus are flightless birds.
B/Ancient cave paintings depict humans and bulls thousands of years ago.
C/More than 96% of human DNA is identical to chimpanzee DNA.
D/In the early stages of embryonic development, humans, rabbits, fish, and salamanders look very similar.
E/Scientists discovered eight genetic variants in four regions of the human genome that influence skin color ranging from very light to very dark.
A biologist is trying to infer how five closely related species of snakes are related to one another. She notices that some of the snakes have forked tongues and others do not. Which of the following would help her distinguish the ancestral state?
Group of answer choices
She looks at a representative mammal species to see if it has a forked tongue.
She locates a specimen of a more closely related snake to see if it has forked tongue.
She looks among snakes fossils for evidence that being forked is a characteristic of the ancestor of this group, but determines no such fossil exist.
She flips a coin.
How do fossils provide evidence that evolution has happened on Earth?
a. Fossils show that some species have gone extinct.
b. Fossils show how life forms present today are different than those from the past.
Fossils show how the sizes of certain animals has changed drastically over millions of
с.
years.
d. Different sedimentary rock layers provide evidence for how the environment has
changed over time.

- Which concepts characterized Lamarck's hypothesis about evolution? Select all that apply. Over many generations, individuals that have more adaptive traits tend to survive longer and reproduce more than less fit rivals. Environmental pressures caused an internal requirement for change in an individual, and the individual would change to meet this pressure Species gradually improved over generations due to an inherent drive toward perfection. Changes acquired to meet environmental pressures during an individual's lifetime would be inherited by offspring.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. Justify whose idea is more acceptable in science community.arrow_forwardUsing radioactive isotopes to determine the age of a fossil is known as radiometric dating. How might radiometric dating provide support for the theory of evolution by natural selection? Hint—Consider the age of fossils with respect to the overall fossil record (the entire collection of data regarding fossils and the age of Earth).arrow_forward
- The above image shows four different finches that Charles Darwin found while on the Galapagos Islands. This information led Darwin to develop the idea that organisms change, or evolve, over time. Which of these would best describe what Darwin saw as the MAJOR difference(s) between these finches? A) They all ate different food B) They all lived in different areas C) Both where they lived and what they ate were different D) Only their beak size was different and they lived together and ate the same food. Not Gradedarrow_forwardFrom the early 1700s to the modern day, how did various lines of evidence clarify and improve scientists' understanding about the ancestry of cetaceans? A. Anatomyarrow_forwardWhat did Darwin’s travels reveal to him about the number and variety of living species? How did tortoises and birds differ among the islands of the Galapagos? What is evolution? Why is referred to as a theory? Darwin found fossils of many organisms that were different from any living species. How would this finding has affected his understanding of life diversity?arrow_forward
- describe at least one reason why Darwin was right and Lamarck was wrong when it came to explaining evolution, using giraffes to explain your reasoning.arrow_forwardA scientist used satellite images to track the natural habitats of two species of salamanders: E. eschscholtzii (shown in green) and E. klauberi (shown in brown). What type of evidence of evolution is this? *arrow_forwardWhy was Jean Baptiste Lamarck wrong about the mechanism of evolution? A. Because giraffes haven't evolved in billions of years. B. Because individuals do not pass on any traits that they acquire during their lifetime. C. Because individuals can change their traits during their lifetime and pass on those traits to their offpsring. D. Because he misunderstood the structure of DNA.arrow_forward
- Using radioactive isotopes to determine the age of a fossil is known as radiometric dating. How might radiometric dating provide support for the theory of evolution by natural selection? Hint—Consider the age of fossils with respect to the overall fossil record (the entire collection of data regarding fossils and the age of Earth). “Navy coffee” is where the coffee is brewed strong and a bit of salt is added. What is special about water that allows you to put sugar or salt in your coffee? To help answer this question, consider the opposite situation: Why do salt scrubs that you buy in a high-end spa consist of large salt crystals in oil?arrow_forwardThe Theory of Evolution contends that species have changed through time and are related to one another through descent from a common ancestor. Which of the following prediction follow from the Theory of Evolution? A. The fossil record should contain intermediate forms between major taxonomic groups B. The oldest rock strata are much more likely to contain complex fossils than simple fossils. C. Fossils are always a representation of species that are currently alive (ie extant) even if they have not been detected yet as living on earth at the present time D. All species are unigue and originated independently from each otherarrow_forwardwhich statement serves as evidence that Darwin’s theory of evolution had prediction power? a. It could be proven incorrect with the discovery of fossils of complex organisms found in the oldest fossil deposits. b. It could be proven incorrect with the discovery of amphibians and large land mammals on remote oceanic islands. c. It could be used to describe the evolution of large-billed finches on the Galapagos Islands. d. It could be used to hypothesize that fossils of the most primitive human ancestors would be found on the African continent.arrow_forward
