Suppose scientists are monitoring the changes to a population of fish in a tank over several months. Which scenario below best describes 'natural selection'? O A predator is introduced, and feeds on slower fish more than faster fish. A group of 200 fish of the same species are introduced into the tank. The fish population experience an algae infection, and only a few fish survive. O Females mate with brightly colored males instead of drab colored males.

Think back to Section 44.6. When researchers moved guppies from populations preyed on by cichlids to a habitat with killifish, the life histories of the transplanted guppies evolved. They came to resemble those of guppy populations preyed on by killifish. Males became gaudier; some scales formed larger, more colorful spots. How might a decrease in predation pressure on sexually mature fish allow this change?
The way an individual's energy is divided among growth, maintenance, and reproduction is controlled by the species' genes and is shaped by natural selection. Different species divide their energy in different ways, but the way energy is divided results in the greatest given the species' niche. O body size o individual survival o lifetime reproductive success
Which is most likely to happen to a population that becomes anatomically isolated from the rest of its species? The entire species will become extinct. The population will become a separate species over time. The population will breed with a different species nearby. O The entire species will continue to have viable offspring together.

EVOLUTION LINK Competition is an important part of Darwins scientific theory of evolution by natural selection, and the evolution of features that reduce competition increases a populations overall fitness. Relate this idea to character displacement and resource partitioning in Darwins finches.

Which of the following set of characteristics would best described a K-selected species (e.g. an elephant)? early reproduction with many, small offspring and short-lived early reproduction with few, large offspring and short-lived late reproduction with few, large offspring and long-lived O late reproduction with many, small offspring and long-lived
MAKE CONNECTIONS Commercial fisheries targetolder, larger cod fish, causing cod that reproduce at ayounger age and smaller size to be favored by naturalselection. Younger, smaller cod have fewer offspring thando older, larger cod. Predict how evolution in responseto fishing would affect the ability of a cod populationto recover from overfishing. What other reciprocal ecoevolutionary effects might occur? (See Concept 23.3.)
Another way to say "Natural Selection" is: differential success in reproduction mutation selective breeding differential access to mating partners variation O preferential sex choices
