Summary Introduction

To explain: The probable characteristics of most recent common ancestors of insects.

Introduction: Studies of insect evolution is aided by molecular, embryological, morphological studies along with bioinformatics. The origin of insects can be dated back to about 480 million years ago. Insect evolution can be traced back to the Ordovician period during which the terrestrial plants also appeared.

Summary Introduction

To enlist: The major lineages that descended from common ancestors of insects.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
