- What major environmental change happened in 1977 and how did this impact the finches?arrow_forwardYou want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page.

How do hummingbirds “know” when it is time to return to their overwintering grounds?arrow_forwardWhich of the following questions is most closely associated with anultimate cause of a behavior?a. How does a squid alter its color to blend in with its environment?b. How does a hummingbird’s body shape influence its ability tohover?c. How do alarm calls affect prairie dog fitness?d. Which cues do monarch butterflies use during migration?arrow_forwardAllan Pounds and Kevin Anchukaitis both think only one factor - either climate change or an El Nino event - killed the golden toad. However, might they both be right? Could it be that the dry conditions created by the El Nino event were worsened by underlying climate change effects, so that El Nino and climate change together caused the extinction of the golden toad in Monteverde? Yes, the El Nino event in combination with climate change could have led to the extinction of the golden toad. Multiple factors can influence species' extinction. O No, only one factor - either climate change or El Nino - acting alone killed the golden toad. Species are only ever affected by one environmental factor, never by multiple factors.arrow_forward
- Do you believe that because insect beak length has changed in opposite directions in the Florida and the Texas populations that we have stronger evidence that natural selection was acting directly on beak length in these populations? Or is it equally likely that natural selection is only acting on a trait correlated with beak length in the Florida and Texas populations?arrow_forwardAncestors of the beach mouse mayhave exhibited variations in their coat color. Because of the prevalence of visualpredators, the better-camouflaged (lighter) mice in the beach habitat may havesurvived longer and been able to produce more offspring. Over time, a higher andhigher proportion of individuals in the population would have had the adaptation of lighter fur that acted to camouflage the mouse in the beach habitat.arrow_forwardA mile-wide river separates two rabbit populations for a million years. Over time, one population evolves long ears and is more active near dark, when they can hear predators coming but the predators can't easily see their ears sticking up above the grass. The other rabbit population evolves short ears and is more active in the middle of the day; it is harder to see, but also doesn't hear predators approaching as well. Eventually the river dries up, and the rabbits start encountering each other again. What do you predict will initially happen when the populations first start to meet? O rabbits will avoid hybridizing, since it is usually a mistake rabbits will interbreed and have offspring with intermediate ears that are visible during the day and not as good at hearing predators at night O rabbits will know not to mate with any that don't have their same "ear size" O rabbits will already show complete reproductive isolation after one million years and will ignore each other, having…arrow_forward
