Genetic Tool kit

 As in the last posts, I will answer some questions based on a video, this time about the genetic tool kit.

1)How has evolution tinkered with genes of animals?

The evolution  altered the genes of animal  to adequate animals to the changing condition of the evironment they  are living in.
2) What role has embryos played in the study of evolution?
All animals come from similar types of cells. By studying the embryos, we can analyse how this cells specialize to make a particular function.
3) What did the experiment with fruit flies and mice show?
It shows that they share some same genes because they have a common ancestor. Beside this, it is important to notice that there are many different different factors that make the gene produce a specific kind of eye, arm, leg, etc.. to a specific animal.
4) What does the presence packages of information suggest about evolution?

It suggests that all animals come from a common ancestor that passes the package of genes, wich show why they have similar genes. Finally, although they share the same genes, other factors like the evironment, food and weather determine the evolution path each race follows.
