- What effect does the level at which natural selection operates (genes, individuals, or groups) have on human free will?Natural selection and artificial selection or selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. Changes in genetic traits have occurred over generations through both natural selection and selective breeding although the occur through different means. What characterizes only artificial selection? Choose all that apply. A) chickens that lay larger eggs are favored B) selection increases the chances of surviving C) selection make a species stronger and fit for survival D) selection favors the desired characters in the new organismsHow does competition influence natural selection? Is the presence of competitors a selective force?
- What is fitness according to evolution?What is the difference between natural selection and sexual selection?Nursing bees take care of the queen and newly hatched bees. However, nursing bees themselves do not reproduce. How could natural selection act upon such behavior? Because this behavior does not directly benefit the nursing bee itself, it is not favored by natural selection. Because this behavior increases the number of surviving offspring that share genes with the nursing bee, it is favored by natural selection. Because this behavior selectively decreases the number of offspring harboring non-similar genes with the nursing bee, it is favored by natural selection. Because this behavior does not increase the number of surviving offspring that are identical in genes with the nursing bee, it is not favored by natural selection.
- Define natural selection in relation with reproductive success ?Define natural selection using the 5 points below to explain its role in understanding primate behavior. (1) there is variation among individuals; (2) some of that variation is heritable; (3) there is always competition between individuals for resources; (4) some variants outcompete other variants and leave more offspring; (5) to the extent that the parent's traits are heritable, then a larger portion of the next generation will reflect those traits.Darwin proposed natural selection as a mechanism for evolution. How is it similar to artificialselection? How is it different? For natural selection to work, there must be genetic variation within a population as well asmutations? Why must there be both?What is the difference between natural selection and sexual selection?
- Assume you are studying a species of slug where the eggs are fertilized and transferred to the male. As a result the male is not able to increase reproductive success by mating with multiple partners. Therefore which of the following about sexual selection in this species is not true? Females are more likely to develop traits that signal genetic quality to males. Females will be able to increase reproductive success with increased mating partners. Sexual selection in males will lead them to be choosy with what females they mate with. Sexual selection in males will lead them to mate indiscriminately when they find a female.So how can individual selection result in low reproductive rates or short life spans?Why is negative selection important?
