Which is a reproductive strategy used by males?
The Ideal Male Reproductive Strategy The optimal reproductive strategy of a hypothetical male primate is characterized by rapid sexual maturation, followed by life-long exclusive access to an unlimited number of fertile females willing to mate, and offspring survival should be independent of paternal care.
What are three key factors that contribute to a female primate’s success at feeding?
Quality, distribution, and availability are the three key factors that contribute to primates' success at feeding.
What behaviors do natural selection generally favor?
Natural selection generally favors behaviors that: a. enhance survival and reproduction.
How do primates acquire food?
2) primates rely entirely on their bodies for acquiring and processing food for consumption. Humans rely on extrasomatic means-material culture-to acquire and process food. Chimpanzees, orangutans, and some New World monkeys employ rudimentary technology, reflecting socially transmitted knowledge.
What is a reproductive strategy?
The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring. It could refer to things like sexual vs. asexual reproduction. It could also refer to one reproductive episode in a lifetime, semelparous reproduction, vs.
How do male and female mating strategies differ?
While males generally pursue a short-term mating strategy when possible, females typically pursue a long-term mating strategy. Long-term strategies are characterized by extended courtships, high investment, and few sexual partners.
What are three key factors that contribute to a female primates success at feeding quizlet?
Three key factors that contribute to a female primate's success at feeding are: quality, distribution, and availability of food.
Which factor is typically most limiting to female reproductive success in primates?
Because female mammals invest much more heavily than males in individual offspring through gestation and lactation, their reproductive success is usually limited by their ability to turn food resources into offspring, while male reproductive success depends more on their access to mates (1).
How do male and female primates differ in reproductive strategies?
Because the reproductive physiology of male and female primates differs (males produce sperm and cannot gestate or lactate; females produce eggs and gestate and lactate), males and females differ with regard to parental investment and sexual selection strategies. Female strategies, on the one hand, focus on obtaining …
What type of selection is shown when females select males which have better traits?
sexual selection, theory in postulating that the evolution of certain conspicuous physical traits—such as pronounced coloration, increased size, or striking adornments—in animals may grant the possessors of these traits greater success in obtaining mates.
How long do chimps drink milk?
Chimp mothers wean their young at about age 5. Gorilla moms stop nursing when their offspring are about 4.
What is the ultimate goal of reproductive strategies?
Regardless of which reproductive strategy a species develops, the goal of all the strategies on the r/K-selection continuum is the successful production of enough offspring to, at least, replace the parental generation.
What are the reproductive strategies for plant reproduction?
Sexual reproduction in flowering plants involves the production of separate male and female gametophytes that produce gametes. The anther produces pollen grains which contain male gametophytes. The pollen grains attach to the stigma on top of a carpel, in which the female gametophytes (inside ovules) are located.
What is the meaning of reproductive strategies?
A reproductive strategy is defined as the way in which a species allocates or budgets energy to produce viable offspring. Energy is diverted into actual offspring and into parental care.
What are the three primate tendencies that contributed to their successful distribution?
Quality, distribution, and availability are the three key factors that contribute to primates' success at feeding.
Which of the following is one of the three key ways in which primate societies are diverse?
(Q002) Quality, distribution, and availability are the three key factors that contribute to primates' success at feeding. Which of the following is true of such success?
Why are females generally more selective when choosing mates?
Females tend to be the choosier sex when it comes to selecting a mate, partly because males can produce millions of sperm, whereas females' eggs are few and far between. Thus, females may be more selective because they have more invested in each gamete and in the resulting offspring.
Why do females choose mates?
For many birds and mammals, natural selection appears to favor females who choose mates that provide them with some direct benefit that will increase their fecundity, their survival or the survival of their offspring. Such benefits might include food, a safe haven or even the prospect of fewer parasites.
Why do mother monkeys bite their babies?
It turns out that's just what happens in one rhesus macaque society. When a mom doesn't give in to her baby's demands, it risks being smacked and bitten by its fellow monkeys. Rhesus monkey babies cry when they want to nurse.
Why do humans breastfeed animals?
The reasons for this are varied: to feed young animals, to drain a woman's breasts, to promote lactation, to harden the nipples before a baby is born, to prevent conception, and so on.
What is reproductive strategy?
A reproductive strategy is defined as the way in which a species allocates or budgets energy to produce viable offspring. Energy is diverted into actual offspring and into parental care.
What’s a reproductive strategy?
The term reproductive strategy is loosely used to refer to the way an animal mates and/or raises offspring. It could refer to things like sexual vs. asexual reproduction. It could also refer to one reproductive episode in a lifetime, semelparous reproduction, vs.
What are two examples of reproductive strategies?
Examples include breasts, showy tails and headpieces, and crazier traits like the length of the eye-stalks in stalk-eyed flies. Sexual dimorphism can lead to specific behaviors in males that increase their reproductive success.
When you were an 18 year old in high school your parents insisted that you were still an adolescent and therefore incapable of living an adult life?
(Q004) When you were an 18-year-old in high school, your parents insisted that you were still an adolescent and therefore incapable of living an adult life. Which of the following, however, is an example of how you were already like an adult? Your brain was already full size.
What are 3 adaptations inherited from our primate ancestors that enable humans to make use of tools?
What adaptations inherited from our primate ancestors enable humans to make and use tools? Several primate characteristics make it easy for us to make and use tools: mobile digits, opposable fingers and thumb, and great sensitivity of touch.
Which of the following are true regarding females with good nutrition correct answer s?
Which of the following are true regarding females with good nutrition? Correct Answer(s): – They have healthier offspring.
How do human females choose mates?
Some of the factors that affect how females select their potential mates for reproduction include voice pitch, facial shape, muscular appearance, and height. Several studies suggest that there is a link between hormone levels and partner selection among humans.
What do men look for in a woman?
Men love women who are thoughtful, caring, loving and kind. A woman who does little things for her man for no other reason other than that she loves him. A woman who makes him smile back whenever she smiles at him. A woman who radiates love and warmth from her heart.
Why mating is important?
To transfer their genes to the next generation successfully, animals need to choose a suitable mate. Failure to do so leads to low or no reproductive success — that is, poor fitness. But reproductive success can also hinge on the number of mates, and on social interactions that extend beyond mating.
Why do monkeys throw poop?
Not only is throwing poop or objects an emotional release for chimps but it is a form of communication. The better the chimp is at hitting the target, the better their communication is amongst the group.
