Textbook Question
Chapter 22, Problem 3AWK
Critics of evolution often charge, correctly as it turns out, that the fossil record is incomplete and scientists cannot show how all living things evolved over time. Why don't we have a complete record?

Students have asked these similar questions
What evidence did Georges Cuvier present that contradicted one of Jean-Baptiste Lamarck’s ideas?
he argued that specimens in the fossil record never changed much, so evolution was not occurring
he demonstrated that the Indian elephant and the African elephant were two different species
he claimed that divine creation was necessary to explain the origin of a new species
he argued that natural catastrophes, like floods and ice ages, were common in the history of life
he identified fossil specimens of two large, extinct mammal species (the mammoth and the mastodon)
what do you want to know about how humans evolved? From what you know already from school or tv, what questions do you think are unanswered about how we came to be? What doesn't make sense yet?
What characteristic(s) of the fossil record make(s) it strong support of evolution?
a) It has fossils of many species in it that are not found on earth today.
b) It is has a complete record of every form of life ever existing
c) Species appear in sediment layers in a consistent pattern
d) All fossils are similar to living forms found in the same area as the fossils

- Scientists classify living things in order to organize the astonishing diversity of life on Earth. Modern scientists base their classifications mainly on molecular similarities. They group together organisms that have similar proteins and DNA. Molecular similarities show that organisms are related. In other words, they are descendants of a common ancestor in the past. As we said earlier in our discussion, there are species that needs to be named and some are to be discovered. However, with the current environmental situation we have at the present (pollution, exploitation of resources, forest fires, and others), these species that are yet to be identified are being endangered and at the verge of extinction. As a matter of fact, the University of Turku reported last July 1, 2020 that there are 15 million estimated different species living in our planet but 2 million of them are currently known to science. Discovering these remaining species is important for them to be protected. Also,…arrow_forwardEvolution is the theory that species change over time. According to this theory, new species form from existing species through variation and natural selection. The evolutionary process is very slow and the transformation of one species into another requires thousands of years. Several evidences are used to prove evolution and somehow reconstruct how this process occur: 1.Fossil Records. 2.Homologous Body Structures. 3.Vestigial structures. 4.Similarity of embryo. 5.Geographical evidencearrow_forwardThe theory of evolution has long been a part of the study of biology in its attempt to explain the diversity of different life forms. Why do you think has it not been elevated as a Law?arrow_forward
- What 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_forwardWhat is an evolutionary tree? Is there a precise evolutionary tree known by science that explains the emergence and origin of every type of living being?arrow_forward. The images below show two separate theories of how organisms evolve. Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? Why don’t the shorter neck giraffes feed on grasses and lower vegetation? How would the shorter necked giraffes in Lamarck’s theory survive to reproduce and pass on the “need” for longer necks if they were unable to reach food? Why won’t the taller necked giraffes in Darwin’s theory provide assistance to the shorter giraffes since they are the same species? Will the smaller giraffes be more adapted to hide from predators since they wouldn’t be visible from greater distances?arrow_forward
- Which of the following statements about convergent evolution is true? (a) It demonstrates how similar environments can lead to different physical structures. (b) It demonstrates how similar environments can lead to the same physical structures. (c) It demonstrates that similarity of structures is due to descent from a common ancestor. (d) It demonstrates that similarity of structures is due to random chance.arrow_forwardWhich statement is true? Fossils can provide information about when life forms existed. Fossils cannot provide information about life cycles and behaviors. Fossils cannot provide information about relatedness of life forms. Fossils can provide information about the entire evolutionary process of life forms.arrow_forwardEvolution is based on which of the following concepts? (a) organisms share a common origin (b) over time, organisms have diverged from a common ancestor (c) an animals body parts can change over its lifetime, and these acquired changes are passed to the next generation (d) a and b (e) a, b, and carrow_forward
- What is the difference between micro- and macroevolution? a. Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants. b. Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms. c. Microevolution describes the evolution of populations, while macroevolution describes the emergence of new species over long periods of time. d. Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.arrow_forwardThrough _______, a body part of an ancestor is modified differently in different lines of descent. a. homologous evolution c. adaptive divergence b. morphological convergence d. morphological divergencearrow_forwardHow are transitional fossils evidence to support the process of natural selection? They show that most species have not changed over long periods of time. They show plants and animals that once existed but do not exist now. They show intermediate steps in the evolution process. They show that every species of animals developed separately.arrow_forward
