Chapter 18, Problem 14TYU
EVOLUTION LINK Write short paragraphs explaining each of the following statements:
(a) Natural selection chooses from among the individuals in a population those most suited to current environmental conditions. It does not guarantee survival under future conditions.
(b) Individuals do not evolve, but populations do.
(c) The organisms that exist today do so because their ancestors had traits that allowed them and their offspring to thrive.
(d) At the molecular level, evolution can take place by the replacement of one
(e) Evolution is said to have occurred within a population when measurable genetic changes are detected.

- Why is intelligent design (ID) a flawed argument? Select the statement that is FALSE. There is no way through experiments or observations to falsify the hypothesis of an Intelligent Designer. ID assumes that each molecular machinery is built from scratch, which is not true; existing proteins are often re-used. OID and evolution are both valid hypotheses, but over the years we have found more evidence pointing toward evolution. O ID assumes that systems are irreducibly complex, and that individual components cannot be removed, even though several examples exist of 'irreducibly complex' systems being reduced. en 0 3 $ 35 % ^ 6 18 & * 8 9 44 Indoor Playground with wheelsarrow_forwardHello! I have a discussion tommorow with my classmates, and the prompt says like this: Discuss whether changes to an organism's physical environment are likely to result in evolutionary change. Use examples to support your reasoning. Second, using at least two examples, explain how the process of evolution is revealed by the imperfections of living organisms.arrow_forwardThe Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes. In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point.arrow_forward
- When two organisms are very distantly related in an evolutionary sense, (a) they should have extremely similar embryonic development. (b) they must share a very recent common ancestor. (c) the sequences of DNA in their genes should be less similar (more different) than those of two more closely related organisms. (d) they should share more homologous traits than two more closely related organisms share.arrow_forwardCharles Darwin came up with several original ideas in his 1859 publication The Origin of Species. Some of these ideas are now generally accepted, some are still hypothetical, some are conditional, and some are now believed to be incorrect. List several of his ideas (including at least one from each category), and explain why each of these ideas are either: (1) considered to be essentially correct, (2) considered to be hypothetical, (3) considered to be conditionally correct, or (4) considered to be incorrect.arrow_forwardAsian tiger mosquito Trace its origin and evolutionary history or changes in the species. Describe its structures and their functions. What is the importance of this species to our environment? Give trivia about this species. Does this organism produce oxygen? Explain. What are the ancestral species of your chosen organism? Has this species been genetically engineered? If yes, in what way? How does this species reproduce? What organisms have similar structures to this species? Do these structures have the same function? Does the species have tissues, organs, and/or organ systems? What is its role in the flow of energy? Give at 15 least a sentence to each question.arrow_forward
- Evolution, which involves genetic changes in a population of organisms over time, is often described as the unifying theme in biology. Discuss how evolution is unifying at the molecular and cellular levels.arrow_forwardIn evolutionary terms, an organism's fitness is measured by its 1. a) population rate changes due to environmental pressures 2. b) contribution to the gene pool of the next generation 3. c) rate of genetic variability across mitotically changing exons 4. d) mutation rate due to genetic drift 5. e) all of the abovearrow_forward. DNA sequences in many human genes are very similar to thesequences of corresponding genes in chimpanzees. The mostlikely explanation for this result is that(A) humans and chimpanzees share a relatively recent common ancestor.(B) humans evolved from chimpanzees.(C) chimpanzees evolved from humans.(D) convergent evolution led to the DNA similarities.arrow_forward
