DDI is an insecticide that was used extensively in the mid-1900s to kill mosquitoes. It was very effective at first, but after a few decades DDT became less effective at killing mosquitoes because many populations had evolved resistance to DDT. Which of the following conditions would biologists say was required for the evolution of DDT resistance in a population? The mosquito population needed to evolve DDT resistance in order to avoid extinction. A few mosquitos were resistant to DDT before it was ever used. Exposure to DDT caused specific, nonrandom mutations for DDT resistance within the population. Mosquitoes in the population had learned to adapt to the high levels of DDT in the environment.

What benefits would occur if there wasan international database of DNA fromendangered and threatened species?
Perhaps 98 percent to 99 percent of all species that have ever existed areextinct. Nearly all went extinct long before humans arrived on the scene. Whyshould we be concerned about the extinction of organisms today?
EVOLUTION CONNECTION The fossil record indicates that therehave been five mass extinction events in the past 500 millionyears (see Concept 25.4). Many ecologists think we are on theverge of entering a sixth mass extinction event. Briefly discussthe history of mass extinctions and the length of time it typicallytakes for species diversity to recover through the process ofevolution. Explain why this should motivate us to slow theloss of biodiversity today.

House 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.
KO> O The diagram below represents four different species of bacteria. Species A Species B Species C Species D TTT Which statement is correct concerning the chances of survival for these species if there is a change in the environment? O Species C has the best chance of survival because it has no gene mutations. O Neither species B nor species D will survive because they compete for the same resources. O None of the species will survive because bacteria reproduce asexually. O Species A has the best chance of survival because it has the most genetic diversity. 1 4 7 8 10 Next O 1 N CH I O
