Concept explainers
Although many chimpanzees live in environments with oil palm nuts, members of only a few populations use stones to crack open the nuts. The likely explanation is that
(A) the behavioral difference is caused by genetic differences between populations.
(B) members of different populations have different nutritional requirements.
(C) the cultural tradition of using stones to crack nuts has arisen in only some populations.
(D) members of different populations differ in learning ability.

- Dolphins and humans both have the ability to nurse their young, whereas the less closely related sharks do not. The ability to nurse their young is (a) a shared derived character of fish and mammals (b) a shared ancestral character of all vertebrates (c) a shared derived character of mammals (d) anexample of homoplastic behavior (e) an example of reversalarrow_forwardA)Research shows that Neandertals coexisted with at least three other species, including Homo sapiens. There are some humans today that have Neandertal and Denisovan genes. Generate a hypothesis about how their genes are also a part of our genes. B) Using this information: In 1993, primatologist Richard Wrangham proposed that "Bonobo hypersexuality appears closely linked to the evolution of female-female alliances. I suggest that these alliances were made possible by relaxed feeding competition."Generate a hypothesis about why Bonobos behave this way..arrow_forwardWhich is the best possible hypothesis for explaining changes in cortical robusticity over time? a.) The decrease in cortical robusticity associated with the appearance of modern humans was rapid and dramatic and resulted in more lightly constructed skeletons. b.) The increase in cortical robusticity associated with the appearance of modern humans was gradual and resulted in larger brain size coupled with a greater ability to deal with predators l. c.) The decrease in cortical robusticity associated with the appearance of archaic Homo sapiens is a part of a long term trend beginning with australopithecines and ending with modern Homo sapiens. d.) None if these statements are an appropriate hypothesis for changes seen in cortical robusticity.arrow_forward

A) These bones helped to improve chewing, allow ancient mammals to diversify their diet. B) These bones improve hearing by allowing vibrations to be better picked up in air and the detection of higher frequencies. C) These bones allowed the detection of vibrations (hearing) for the first time in evolutionary history. D) These bones improve vision by providing an additional anchor point for the optic nerve.arrow_forward
- Living things can inherit behavior, learn it from other creatures, or change their behavior because of their environment. Which example describes learned behavior in a living thing? A) Sunflowers turn to face the Sun to help them grow. B) Most humans begin to speak when they are one or two years old. C) Glowing Click Beetles can produce light from the back of their head for protection. D) A sea turtle that hatches on a beach will crawl toward the ocean.arrow_forwardSuggest a probable selective advantage of each of the following traits. a)clear wings of many flying insects b)long tongue of a chameleon c)tendrils of climbing plants d)eel's body shapearrow_forwardAccording to Hamilton’s rule,(A) natural selection does not favor altruistic behavior thatcauses the death of the altruist.(B) natural selection favors altruistic acts when the resultingbenefit to the recipient, corrected for relatedness, exceedsthe cost to the altruist.(C) natural selection is more likely to favor altruistic behaviorthat benefits an offspring than altruistic behavior thatbenefits a sibling.(D) the effects of kin selection are larger than the effects ofdirect natural selection on individuals.arrow_forward
- explain how humans are related to each of the following animals by indicating the level of relatedness and which traits are evidence for this level of relatedness a) lamprey b) sea star c) beetlearrow_forwardPlease answer fast The human revolution may be characterized as ____. It is largely untenable as evidence of _____ has been found. a) modern human behavior occurring first in Australia; modern behavior from Oceania b) a brain mutation occurring when Homo habilis began making stone tools; Australopithecus afarensis producing Oldowan tools a million years earlier c) a brain mutation occurring when modern humans began leaving Africa; evidence of modern behavior in Africa predating this "revolution" d) The beginning of agriculture in the fertile crescent in the Near East and along the Yangtze and Hwang Ho rivers in China; Agriculture occurring earlier along the Nile river.arrow_forwardWhich research question does not refer to proximate causes of behavior? a.) How do rhesus macaques find their food? b.) how do pigeons that are experimentally displaced find their way back to their home loft? c.)
