A species of Caribbean fish lives in groups of individuals in a burrow in the sand. When a predator swims by, one or more of the fish flick their fins to warn others to retreat to the safety of the burrow. Fish that flick their fins are more likely to be killed by predators than fish that do not. What is the most useful piece of information you would like to know in order to explain how fin-flicking can evolve, and why?

It has taken millions of years for the ancestors of whales to change into what we know today, as indicated in the diagram below. Based on your knowledge of evolution, which of the following is a reasonable explanation of why the organisms in the diagram changed over 25 million years? Question options: As the environment changed the food sources became more difficult to obtain so characteristics that allowed the organisms to hunt in an aquatic environment became more advantageous. As the environment changed the temperature became too hot and the organisms began to move to a more aquatic environment to keep cool. As the environment changed the food sources became more difficult to obtain so the organisms decided to change their characteristics to ones that would be beneficial when hunting in an aquatic environment. As the environment changed the predators on land became better adapted to hunting the whales ancestors forcing them to live in more aquatic…
Of the following, which one is an example of an evolutionary explanation (as opposed to a functional explanation)?A. People evolved a fear of snakes because many snakes are dangerous.B. Humans have a (tiny) tailbone because our ancient monkey-like ancestors had a tail.C. People evolved an ability to recognize faces because that ability is essential for cooperative social behaviors.D. People evolved a tendency to form long-term male–female bonds because human infants benefit from the help of two parents during their long period of dependence.
According to Lamarck’s theory of evolution, organisms change during their lifetime to survive then pass these changes to their offspring. What supports the hypothesis of Lamarck? a. Webbed toes of ducks to quickly move through the water, retractile claws of carnivorous mammals to catch the prey, millipede producing awful smell for self-defense and evolution of short-necked to long-necked giraffe b. Evolution of short-necked to long-necked giraffe, webbed toes of ducks to quickly move through the water, disappearance of limbs in snakes and retractile claws of carnivorous mammals to catch the prey c. Rattlesnake producing venom against predators, jellyfish bioluminescence for intraspecific communication chameleons camouflage to hide from predators and millipede producing awful smell for self-defense d. Disappearance of limbs in snakes, chameleons camouflage to hide from predators, evolution of short-necked to long-necked giraffe and rattlesnake…
Lampreys are jawless fish. Which conclusion about lamprey evolution is supported by the evidence in the diagram? A. Lampreys developed after hinged jaws formed. B. Lampreys once had hinged jaws but lost them during evolution. C. Lampreys are invertebrates and could not develop hinged jaws. D. Lampreys diverged from other vertebrates before hinged jaws evolved.
Many species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?
Honey possums lick nectar from flowers using a long tongue made of soft muscle. Butterflies lick nectar from flowers using a long tongue made of hard protein. What type of evidence is this? Why is this evidence of evolution?
If natural selection has no foresight,how can it explain features that seem to prepare organisms for future events? For example, deciduous trees at high latitudes drop their leaves before winter arrives, male birds establish territories before females arrive in the spring, and animals such as squirrels and jays store food as winter approaches.
Consider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.
Flying fish use large pectoral fins to glide in air. Explain how Lamarck and Darwin might account for the origin of the large pectoral fins and the ability to glide.
Which is an example of evolution? In Florida, the brown tree lizard has taken the trees from the green tree lizard. The feet of green tree lizards have become less sticky in recent years, making it harder for the green lizards to climb higher in the trees to escape the brown tree lizards. Mice have become more sensitive to poison, which has resulted in them dying quicker when they eat the poison in mouse traps. Bed bugs have developed thinner exterior shells and more sensitive nerve cells that are less resistant to the chemicals that are used to kill them. Due to global warming, the winters in Finland have been milder, resulting in less snow. The brown tawny owls in Finland are showing higher survival rates than the pale grey owls because they can blend into the trees to hide from predators.
Assume that a lineage of rainbow trout accumulates mutations over time that make the trout a uniform dark brown with orange spots and produce a dorsal fin shape that is very different from all other rainbow trouts. This group of rainbow trouts also has lips that are twice the size of other rainbows and they have a much narrower body. How do we know when the natural selection of such characteristics results in a new species of fish?
Which is a question Lamarck MOST LIKELY would have asked when developing his evolutionary hypothesis? A. Is artificial selection the basis for evolution? B. Is evolutionary change the result of survival of the fittest? C. Can body structures change according to the actions of the organism? D. Can a small population size increase the rate of evolution?
