Which sense is primarily involved in the identification of a pheromone that increases anxiety in rats?
Smell
What is the main purpose of the larynx in birds?
Controlling the voice and song
How do bats locate objects using their echolocation?

In the context of sibling rivalry, which animal shows evidence of intense competition?
Frigatebird
What is the primary function of the tapetum lucidum in marine mammals?
To enhance vision in low light conditions
What is one unique trait of the proboscis monkey mentioned in the text?
Unusually large nose
Based on the text, why might some female proboscis monkeys prefer males with larger noses?

What is the significance of the elephant's trunk, or proboscis, mentioned in the text?
Fusion of nose and upper lip
What is a reason for the African elephants having two 'fingers' at the end of their trunks?
To grasp more items
How does the size of the proboscis monkey's nose relate to its vocal abilities?
It increases vocal volume
Why is the development of parent-offspring recognition in altricial species delayed until shortly before it is required?
Earlier recognition could lead to evicting one's own chick by mistake.
Why do blue-footed boobies tend to mate with younger individuals who have brighter feet?
Brightness of feet indicates higher fertility and ability to provide paternal care.
How does asynchronous hatching contribute to sibling rivalry among blue-footed boobies?
Asynchronous hatching results in a growth inequality between siblings.
In the context of communication among blue-footed boobies, what role does the blue color of the feet play?
The blue color represents the bird's nutritional state and immunological health.
What is the significance of the brightness of blue-footed boobies' feet decreasing with age?
Younger birds with brighter feet are perceived as better mates.
How does size disparity due to asynchronous hatching lead to facultative siblicide?
Size inequality can drive competition between siblings, resulting in siblicide.
What potential risk is associated with recognizing offspring too early in altricial species?
Mistakenly accepting alien chicks into the nest.
What evolutionary advantage might asynchronous hatching confer upon blue-footed boobies?
It increases the chances of at least one chick surviving in times of food scarcity.
Why do blue-footed boobies tend to prefer partners with bright feet?
Bright feet indicate youth and fertility which are attractive traits for mating.
How does the brightness of the feet of blue-footed boobies change with age?
The brightness decreases with age as a sign of decreased fertility and care abilities.
