Textbook Question
Chapter 12, Problem 7WIO
Jellyfish Lake, located on the Pacific island of Palau, is home to millions of jellyfish. Many years ago, sea levels dropped and the jellyfish were trapped in the basin. The lake co mains no predators, and the jellyfish’s sting has weakened. Jellyfish Lake is now a popular to urist attraction where snorkelers can swim among the jellyfish. Explain how Jelly fish Lake is evidence for evolution.

Charles Lyell's contribution to evolution is the idea that:
O the earth is more than 6,000 years old
O species evolve
O natural selection is the mechanism of evolution
there will always be a shortage of resources
A human and a monkey have fewer differences in amino acids of the
protein hemoglobin than do a human and a frog. What is the
explanation for this evidence?
O Frogs and humans are more closely related than humans and monkeys.
Humans evolved from monkeys.
O Monkeys evolved from frogs.
Humans and monkeys share a more recent common ancestor than
humans and frogs.
Charles Darwin, brn in England,postulated natural selection, he assorted that only the strongest and fittest will survive and this he called natural selection . His theory was that the weaker species will eventually die and the strongest species will survive.
Relate this theory to one from the 19th or 20th century.

- Two species of fish had recently undergone sympatric speciation. The males of each species had a different coloring through which females could identify and choose a partner from her own species. After some time, pollution made the lake so cloudy it was hard for females to distinguish colors. What might take place in this situation?arrow_forwardEVOLUTION LINK Charles Darwin once said, It is not the strongest of the species that survive, nor the most intelligent, but the one most responsive to change. Explain what he meant.arrow_forwardWRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.arrow_forward
- Adaptations B Fossils Ancestral structures Homologous structures 2. The process by which individuals that are better adapted to their environment are more lik to survive and reproduce than other members of the same species is called Natural selection Evolution C Competition Over production 3. Which of the following is the best example of an adaptation that helps organisms surviv their environment? A green coloring in lizards living on gray rocks B. a thick coat of fur on animals that live in the desert an extensive root system in desert plantsarrow_forwardHouse sparrows (Maya) were introduced to North America in 1852. Since that time thesparrows have evolved different characteristics in different locations. Sparrow populations inthe north are larger-bodied than sparrow populations in the south. This divergence inpopulations is probably at least partly a result of natural selection: larger-bodied birds canoften survive lower temperatures than smaller-bodied birds can. Colder weather in the northmay select for larger-bodied birds. What type of evolution based on natural selectionaccounts for this observation? Explain your answer.arrow_forwardThe fossil record shows that over time: features of organisms change after death features of living organisms cannot be observed features of living organisms have remained constant O changes have occurred to features of living organismsarrow_forward
- For the following question, first, explain if it is true or false. If false correct the underlined word to make it true. If you do not correct it then you will lose all points. There is a bird that still has a gull bladder but, no longer needs to use it this is an example of a vestigial organ. O True O False: Homologous organ O False: Analogous organ False: Natural selectionarrow_forwardMany crustaceans (for example, lobsters, shrimps, and crayfish) use their tails to swim, but crabs have reduced tails that curl under their shells and are not used in swimming. This condition is an example of what evidence of evolution? * Homologous structure Convergent evolution No answer Vestigial trait Natural selectionarrow_forwardCan you please help me with this question The theory of evolution was controversial when it was first proposed in 1859, yet within 20 years virtually every working biologist had accepted evolution as the explanation for the diversity of life.

- Over long periods of time, many cave-dwelling organisms have lost their eyes. Tapeworms have lost their digestive systems. VWhales have lost their hind limbs. How can natural selection account for these losses? The ancestors of these organisms experienced harmful mutations that forced them to lose these structures. Natural selection accounts for these losses by the principle of use and disuse. OIf the function of these structures has diminished over long periods of time, each of these structures presented greater costs than benefits. O Natural selection cannot account for losses, but accounts only for new structures and functions.arrow_forwardEvolution occurs at which level of biological organization? species O populations individuals cells Evolution may occur at any of these levelsarrow_forwardWhy is the following observation by Darwin important to the theory of evolution? "All species can produce more offspring than their environment can support, and many of these offspring fail to survive and reproduce" Organisms have evolved to produce as many offspring as possible Many organisms die for reasons having nothing to do with their evolutionary fitness Competition for resources creates the selection that drives evolution O Over time, organisms that have larger litters will be more evolutionarily successfularrow_forward
