Summary Introduction

To review:

The basis of the phylogenetic tree and the unrooted nature of the fundamental tree of life at the divergence of Archaea, eukarya, and bacteria.

Introduction:

A branching diagram that shows evolutionary relationships among various species represents a phylogenetic or an evolutionary tree. In a tree where the direction of the ancestral relationship is determined based on one of the nodes specified as the root is called a rooted tree whereas an unrooted tree has no pre-determined root and thus, possesses no hierarchy.

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.
