Exam 1: An Overview of Evolutionary Biology

Looking at the table above,predict what will happen if a new antibiotic to the food poisoning bacteria Campylobacter jejuni is developed and prescribed heavily by physicians beginning in 2012.

Which source(s)of data do evolutionary biologists use to test their hypotheses?

The archeological record indicates when people began using various grains and legumes and when these food plants were domesticated.Looking at the figure above,estimate how long humans have been selectively breeding grains.(Note that the gaps in the figure represent periods when no evidence of that crop was found.)

Fisher's sex ratio model was put to test in a species of blue moon butterflies on the Samoan islands of Upolu and Savaii,where which of the following conditions existed?

Charles Darwin was the first person to suggest that

Which of the following statements is (are)true in the absence of competition from other males?

Fisher developed his model partly because so much observational data suggested that the 1:1 sex ratio was common to nature and he wanted to understand why.Is there any natural ordering when it comes to empirical and theoretical approaches?

If chimpanzee and human genomes differ only about 1.3% at the level of DNA base pairs,how can we explain the dramatic differences in appearance,behavior,cultures,etc.,between humans and chimps?

In the figure above,branching points closer to the center of the phylogenetic tree represent

How does the sex ratio study on butterflies in the Samoan Islands demonstrate that important work in science often involves a sound theoretical base,good observational skills,good experimental design,and sometimes a bit of luck?

The five photographs above illustrate some of the sources for the data that evolutionary biologists use to test their hypotheses.Make a short list of other types of data that would be useful for evolutionary biologists to use in their studies,and explain how they would be useful to evolutionary biologists.

How has artificial selection been used to shape the characteristics of food producing plants?

Darwin's theory of natural selection is considered a paradigm shift-a theory that has wide-ranging effects.Describe some of the advantages that this theory offered scientists once it was developed.

According to the phylogenetic tree above,fungi are more related to

In which of the following scenarios are models being used to make predictions and plan for the future?

Considering the table above,which of the following statements is likely true?

More than 100 years ago,Charles Darwin and his colleague Thomas Huxley hypothesized that humans share a common ancestor based on

The loss of which species on the figure above would represent the loss of the most significant phylogenetic diversity?

Fisher's sex ratio model was put to test with a species of blue moon butterflies on the Samoan islands of Upolu and Savaii.Which of the following statement regarding that study are true?

Artificial selection has been used to shape the behavior of farm animals such as the chicken and domestic animals such as the dog.Evolutionary behaviorists believe that natural selection also has affected the appearance and behavior of the domestic dog.Provide a short explanation of how this may have happened.
