Which of the following statements about the grandmother hypothesis is correct? This is a hypothesis used to explain why grandmothers tend to live longer than grandfathers. For this hypothesis to work, a grandmother will need to have an antagonistic pleiotropic mutation that extends her lifespan but also lessens her physical activities. Because grandmothers are older, so they tend to contribute less in a family. That is, grandmothers are usually a drain of resources for a family. The evolution of monthly menstrual cycle in human females is seen as an example explained by the grandmother hypothesis. None of the above

How might an evolutionary biologist explain why a species of salamander becomes blind after colonizing a cave? Group of answer choices Members of the ancestral population that colonized the cave differed in their ability to see. If maintaining the ability to see in the cave was a waste of energy, blind salamanders might actually have more offspring than those who could see. It is possible that in the cave there is a source of pollution that increases the mutation rate for a gene that makes salamanders blind. Over time, due to exposure to this chemical, the membersof the population lose their sight. There is no way to explain this in terms of natural selection. The members of this salamander species no longer needed to use their eyes. Over time, due to lack of use, they lost the ability to see.
Evolution determines the change in inherited traits over time to ensure survival. There are three variants identified as Variant 1 with high reproductive rate, eats fruits and seeds; Variant 2, thick fur, produces toxins; and Variant 3 with thick fur, fast and resistant to disease. These variants are found in a cool, wet, and soil environment. In time 0 years with cool and wet environment, the population is 50,000 with 10,000 Variant 1, 15,000 Variant 2, and 25,000 of Variant 3. Two thousand years past, the environment remained the same with constant average temperature and rainfall. Variant 1 with a population of 26,000, Variant 2, 35,000, and Variant 3, 62,000. A disease spread throughout the population. However the population increased to 72,000. Determine the percentage increase in the population of the variants.
What is an adaptation in the context of evolution? A heritable trait that was favored by natural selection. choose one of the following. A random genetic mutation that causes a new trait in a population. The ability of an individual to adjust to their environment as it changes..
Which of the following statements explains genetic variation? Genetic variation arises ____. When organisms need to change to survive in a new environment. From environmental changes that affect organisms. Through mutation and sexual reproduction. From traits acquired during the lifetime of an organism.
In order for a trait to evolve via natural selection, which of the following must be true regarding the trait? (this is a multiple answer question - so select all correct) Group of answer choices There must be variation in the trait. The trait must make the organism survive longer than organisms with different traits. The trait must confer a reproductive advantage on the bearer of the trait. The trait must be heritable. The trait does not necessarily need to be passed down to offspring.
Which of the following animals may have been the second pet domesticated by humans, in Egypt or in Turkey (about 10,000 BCE), and probably helped to keep rodents away from cereal crops like wheat? the domesticated dog (Canis familiaris) the gray wolf (Canis lupus) the domesticated cat (Felis catus) the coyote (Canis latrans) the Norwegian rat (Rattus norvegicus) The above domesticated animal is thought to have evolved from which of the following species? the African wildcat the house sparrow the gray wolf the mouse the rat
Which of the following mutations in the virtual lab increased the fitness of the rabbits when the conditions were changed to "snow covered"? white fur long legs claws large body
How is variation different from adaptation? * No answer Variation is always caused by mutation while adaptation is a heritable trait. Variation is a difference within an individual organism from the rest of the population. An adaptation is a feature that helps an organism survive in its environment. Adaptation is a difference within an individual organism from the rest of the population. A variation is a feature that helps an organism survive in its environment. Variations are physical or behavioral traits that make an organism better suited to its environment while adaptation comes from random mutations.
The graph below shows values for body size in parents and offspring. The data shown are consistent with which of the following situations. ANSWER CHOICES A. variation in body size is completely due to variation in the environment (heritability is 0) B. most of the variation in body size is due to variation in the environment but there is a small effect of genes (heritability is around 0.2) C. variation in body size is completely due to variation in genes (heritability is 1.0) D. most of the variation in body size is due to variation in genes but there is some effect of the environment (heritability is about 0.8)
Which of the following traits would you expect to be under weakest selection? Explain your answer. The development of prostate cancer in older male humans The development of digits in frogs The silver hair color on silver back male gorillas The dance choreography in peacock spiders
Which of the following best explains the phrase “survival of the fittest” in terms of evolution by natural selection? The strongest and fastest individuals will always survive and reproduce more often. The individuals that are the healthiest will always get more resources and survive better. Only individuals that have the most mates will survive with limited resources. The individuals that survive better and reproduce more often will pass their traits on more often.
Which of these scenarios is an example of disruptive selection? Darker colored morphs in a butterfly population are more adaptive than lighter colored morphs, and lighter colored morphs are eliminated from the population. Intermediate gray morphs of a butterfly population are maintained, and the extreme dark and light color morphs have been eliminated. The dark and light color morphs of a butterfly population are maintained, and the intermediate gray morph has been eliminated from the population. A new, unique color form arises from a mutation in a population of butterflies.
