Group Behavior Quick Check
Which piece of evidence would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior?
C. a penguin protect its chick from seagulls
Which of the following pieces of evidence would be considered the most reliable and valid?
D. data collected from a controlled experiment that has been reproduced in several different labs
Herd behavior benefits wildebeests by
C. helping individuals find mates
Group hunting improved a wolf’s ability to
B. surround prey
Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA.
Which of the following pieces of evidence would be most likely to weaken this argument?
C. Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other
What is a possible consequence for monkeys that exhibit altruism?
**Less fit individuals survive to reproduce.
(for connexus) 2-4 are 100% correct but this is the new question
To summarize:
The evidence that best supports the argument for kin selection as a mechanism for the evolution of altruistic behavior is when a penguin protects its chick from seagulls.
The piece of evidence considered the most reliable and valid is data collected from a controlled experiment that has been reproduced in several different labs.
Herd behavior benefits wildebeests by helping individuals find mates.
Group hunting improves a wolf's ability to surround prey.
The argument that altruistic behavior in groups of related individuals is most likely driven by kin selection can be weakened by data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other.
To answer these questions, we need to understand the concept of kin selection and its role in the evolution of altruistic behavior. Kin selection suggests that altruistic behavior can evolve if it benefits genetically related individuals, as it indirectly increases the chance of passing on shared genes.
Now, let's look at each question individually:
Question 1: Which piece of evidence would best support the argument for kin selection as a mechanism for the evolution of altruistic behavior?
Answer: The correct answer is option C, "a penguin protects its chick from seagulls." This example demonstrates parental care, which is an example of altruistic behavior towards genetically related offspring.
Question 2: Which of the following pieces of evidence would be considered the most reliable and valid?
Answer: The correct answer is option D, "data collected from a controlled experiment that has been reproduced in several different labs." Controlled experiments that are reproduced in multiple labs are considered the most reliable because they provide more confidence in the accuracy and repeatability of the findings.
Question 3: Herd behavior benefits wildebeests by
Answer: The correct answer is option C, "helping individuals find mates." Herd behavior can increase the chances of finding mates by increasing the pool of potential mates and providing safety in numbers.
Question 4: Group hunting improved a wolf's ability to
Answer: The correct answer is option B, "surround prey." Group hunting allows wolves to work together to surround and capture prey more effectively than they could individually.
Question 5: Altruistic behavior in groups of related individuals is most likely driven by kin selection since related individuals would share DNA. Which of the following pieces of evidence would most likely weaken this argument?
Answer: The correct answer is option C, "Data showing that only distantly related individuals are most likely to perform altruistic behaviors in order to protect each other." If the data shows that only distantly related individuals perform altruistic behaviors, it weakens the argument for kin selection as the primary driving force.
