snakes, lizards and puppy dog tails.

As scientists looked at ever smaller and smaller units of matter they found that all living things were made of cells. 

There are only a few basic cell types; muscle, brain, skin or bone. 

Animal cells are different than plant cells.

Although cells are different from each other, depending upon their function, they are also different from the same cells of different species.

There are muscle cells in dogs and snakes. There are brain cells in chickens, cows and men.

 As different as these cells are they are also very much alike. No matter where the cell comes from:

Every protein in our universe is made of the same Amino Acids.

All living things are made of molecules of protein.

It turns out that little boys, girls and all other living things are made of the same stuff.

Both Amino acids and proteins are themselves made of even more basic chemicals.

Let's see what that stuff is.
