Paleontologists and some biologists commonly infer function, andeven behavior, from anatomical details. Skeletal features, forexample, are often used to infer that an extinct mammal (such as anearly hominin) was highly, somewhat, or not at all arboreal. Thisinference assumes a good fit of form to function (i.e., optimalform). Can this assumption be justified?

1. Which of the follow are traits that can be used to make a phylogenetic tree?

a)The bone structure differences between species

b)Similarities in how organs develop between species

c) Based on the differences of the organs found in each species

d)All of the above

E) None of the above

2. Two traits are homologous if:

a)They are what is used to differentiate two population

b)Required for random mating

Any feature that is shared by two or more species

d)All of the above

3. When looking at essential proteins that are conserved amongst different species

a)The only thing to look at is DNA sequence

b)The only thing to look at is a protein sequence
c)

Often the sequences are different but the structures are very similar
