ANIMAL KINGDOM PROJECT

Paragraph:

The first class is the Hagfish, they do,t have the specific characteristics that the other classes have further down the line. The fish, the Perch evolved to have jaws unlike the Hagfish. The Salamander evolved to have  a respiratory system, or in other words, lungs. Then evolved to have claws or nails were the Lizards. Pigeons evolved to have feathers, but that wasn't passed down to the mouse or chimp. The mouse and chimp evolved into the species of mammal that has fur and mammary glands. All through the line the characheristics were passed down to the next evolved animal.
