Questions 1 and 2 refer to Section 11-14 from What Is Life? 1. From: “This Is How We Do It -
When paternity uncertainty seems greater, is paternal care reduced? ” In Experiment 1,
researchers placed two glass containers containing small cuckold males around each nest and
left them there during egg-laying. The cuckold males couldn’t fertilize the eggs, but they could
be seen by the male at the nest.
How much did the presence of cuckold males reduce egg
guarding? How much did it alter offspring guarding? Why was there a difference?
2. From: “This Is How We Do It - When paternity uncertainty seems greater, is paternal
care reduced? ” Considering Experiments 1 and 2 together, what conclusions can you
draw from these results? Why? (Refer to specific results in your answer.)
