A higher selection index value ALWAYS results to better animal performance. Is this true or not? Why or why not?

Suppose a population had three female mice with the following characteristics: Color of Fur White Gray Black Running speed 8 cm/sec. 3 cm/sec. 5 cm/sec. # offspring produced by each female 15 5 Age at death 6 months 3 months 4 months From an evolutionary point of view, which mouse would be the fittest? How do you know?

Which piece of evidence would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior?     an antelope gets separated from the herd and killed by predators a penguin protects its chick from seagulls a clown fish helps clean parasites off of a sea anemone a hippo stops a crocodile from eating an antelope

It has been thought for a long time that zebras had stripes to act as camouflage against lions, their primary predator. However, this hypothesis went untested for a long time. Hypotheses about adaption need to be tested carefully, How might we be able to either gather observational data or do an experiment taht would test the question of wheather stripes are an adaptation to reduce preadation by lions. Include Null hypothesis, the variables you would measure and what your treatment and control groups are.    Just need Null hypothesis and Treatement control as bullet points

EVOLUTION CONNECTION We often explain our behaviorin terms of subjective feelings, motives, or reasons, butevolutionary explanations are based on reproductive fitness.Discuss the relationship between the two kinds of explanation.For instance, is an explanation for behavior such as “falling inlove” incompatible with an evolutionary explanation?

You are a wildlife biologist researching black rhinos. During your time in Africa, you have observed two particular traits that allow some black rhinos to be better adapted to their environment. The first trait is an extra-long prehensile lip that enables the rhino to have more efficient browsing capabilities than rhinos with the usual size prehensile lip. Second, some of the rhinos in the study have extra-large ears that allow them to hear a potential predator earlier than rhinos with normal size ears. If you could breed black rhinos that have both of these good traits (an extra-long prehensile lip (P) and bigger ears (E), it wouldincrease their chance for survival in the wild. You have chosen the following two rhinos to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Parent 1: Heterozygous dominant for prehensile lip trait. Heterozygous for the longer…

Nature vs. nurture is an age-old debate about whether genetics (nature) plays a bigger role in determining a person's characteristics than lived experience and environmental factors (nurture).

Which piece of evidence best supports the hypothesis that the evolution of altruistic behavior is driven by kin selection? A hippo is observed saving an antelope from an attack by an alligator. A cuckoo bird hides its own eggs in the nest of another bird species. A meerkat protects the offspring of its sister from an attack by hawks. A male gorilla helps protect his offspring from an attack by a tiger.

You are a biologist working in the Amazon and you discover two new types of bird that are very similar in appearance.  You want to know if they are the same species or different species. Other than looking at anatomy or DNA samples (which wouldn’t necessarily give you the answer anyway), what behavior could you look at to find out? LIMIT YOUR ANSWER TO ONE SENTENCE

Give an example of how variety in a population can lead to resilience when environments change. (Please make it short)
