what is the best way to tell the sex of a hominin skeleton? - CORRECT ANSWER-from the hips
what is not likely a reason why upright posture in hominins evolved? - CORRECT ANSWER-to
adjust to an environment with more trees
the rapid evolution of flowering plants likely influenced primate evolution in many ways, what is
most likely the reason? - CORRECT ANSWER-made new adaptive opportunities available
what specific types of adaptations and ecological settings would an organismal ecologist study
for their research? - CORRECT ANSWER-they would conduct research examining the
behavioural, morphological and physiological adaptations that allow organisms to survive in a
specific area
what specific types of adaptations and ecological settings would a landscape ecologist study for
their research? - CORRECT ANSWER-they would conduct research examining the specific types
of adaptations associated with controlling the exchanges of energy, materials and organisms
across the mosaic of several connected ecosystems
,how would you use Hamilton's Rule to determine if an individual should exhibit altruistic
behaviour for their relative? - CORRECT ANSWER-if Br>C the benefit of exhibiting altruistic
behaviour is greater than the cost
what is the percent difference in the total nucleotides in chimpanzees and humans? - CORRECT
ANSWER-1.3%
the difference in gene expression between chimpanzees and humans is greatest in which cells? -
CORRECT ANSWER-brain cells
what is looping? - CORRECT ANSWER-the adaptations in one characteristic provide
opportunities for adaptations in another characteristic which provide further opportunities for
adaptations in relation to the original characteristics
what are some examples of characteristics that were likely involved in the same loop in hominin
evolution? - CORRECT ANSWER-brain size, complex foraging, language, sociality, toolmaking,
slow development, clever hands, stereoscopic vision or depth perception
which type of genes in humans are known to be under disruptive selection for diversity? -
CORRECT ANSWER-immune system genes
how does adaptation affect acclimation? - CORRECT ANSWER-adaptation tends to lead to the
evolution of better acclimation responses
, what are 3 pieces of evidence for the idea that species change through time? - CORRECT
ANSWER-vestigial traits, transitional forms in the fossil record, observations of tuberculosis
bacteria that are exposed to antibiotic treatment
blue whales evolved gradually in increasing size, starting from a time they looked more or less
like small hippos, which type of evolution best represents this? - CORRECT ANSWER-goal-
directed evolution
which kind of homology best exemplifies a variety of tetrapods having embryos that look very
similar? - CORRECT ANSWER-developmental homology
what is the most likely explanation for striking similarities between the bone structure of human
arms and turtle flippers, convergent evolution, acclimation, homoplasy or homology? -
CORRECT ANSWER-homology
the lifetime Darwinian fitness of one organism is greater than that of another organism if lives
longer than the other, it is able to outcompete the other for access to resources, it mates more
frequently, or it leaves more viable offspring than the other? - CORRECT ANSWER-it leaves more
viable offspring than the other
male zebras have been observed to stand and face off against hyenas and other large predators
which explanation is the least likely: they are willing to impress female zebras so they can get
more mating opportunities, they are willing to risk their lives to protect the species, they are
willing to risk their lives to protect their offspring, they are willing to save energy by warning the
predators that they have been spotted and are unlikely to succeed? - CORRECT ANSWER-they
are willing to risk their lives to protect the species
do mutations cause little or much evolution directly? - CORRECT ANSWER-little
do mutations affect little or much evolution indirectly by providing variation on which natural
selection acts? - CORRECT ANSWER-much
