I- Many dung beetles have elaborate horns. Male dung beetles use those horns to fight with each other over access to the tunnels in which females can be found (that’s right, a beetle battle). Small dung beetles or beetles with small horns are not successful in these battles. However, their small size and lack of horns allows them to be efficient burrowers. To access females, these small beetles dig side tunnels and access females while avoiding the larger-horned males. This is an example of a…

III- What TWO attributes or characteristics do you think are most crucial with respect to the evolution of multicellularity? In other words, what characteristics must multicellular organisms have or what functions must they be able to successfully execute? Provide a biologically defensible explanation for your answer (5 points)

Be sure you answer the question. I am asking which TWO characteristics you think are most important for multicellularity and why you believe those two characteristics are important. The why part of your answer is the important part. If you simply give me a list of the characteristics of multicellular organisms you will receive no credit. If you describe more than two characteristics, I will deduct two points for each additional characteristic you mention.
