1) How has evolution tinkered with genes of animals?
Evolution can be considered to be all the new combinations of genes that are created, commonly triggered by the external changes (Climate, food availability, etc). 

2) What role has embryos played in the study of evolution?
They are the developing animal, which shape and form is determined by the activated genes and the homeobox. This is the stage of development in which scientists focus their researches. 

3) What did the experiment with fruit flies and mice show?
It showed that the homeobox or genetic tool kit could guide the growing process of any animal, as the genes come from common ancestors. This created a new view about the complexity of evolution.

4) What does the presence  packages of information suggest about evolution?
It suggests that all animals have common genes, but their development is determined by the external factors and by the homeobox.
