Fetal Pig Research Paper

Figure 16 displays the phylogenetic tree for a pig and shows that these species consists of several clades. A clade is specie with one common ancestor and all of its descendants. In Figure 15, the phylogenetic tree shows the very close relationship between the pig (Sus Scrofa) and Sus bucculentus as they have the most recent common ancestor. Figure 15, also shows that sus scrofa is more related to sus verrucisus than sus cebifrons as it closer to the phylogenetic tree.

Taxonomy:

• Kingdom- Animalia

• Phylum- Chordata

• Class- Mammalia

• Order- Primates A primate is a mammal of the order. Many primate represent diverse adaptations to life representing to life in its environment. These primates live in the tropical forests and consist of two main lineages: strepsirrhines and

The organism (earthworm, frogs, or fetal pig) should be taken from a preserving chemical as it prevents the organism’s organs from rotting.

2. Lay the organism (earthworm, frogs, or fetal pig) on a dissection tray with its ventral side up. Garbage bag is sometimes required to prevent any internal fluids from splashing onto the surface.

3. Rinse the organism (earthworm, frogs, or fetal pig) in warm water as it reduces the amount of chemical solution on the organism’s skin.

4. Pin the anterior and posterior end of the organism (earthworm, frogs, or fetal pig) to the dissecting tray. The anterior end of the earthworm, frogs, and fetal frog is the head. The forelegs of the frog and fetal pig are also considered a part of the anterior end. The posterior end of the earthworm is its tail while the hind legs are considered a part of the posterior end of the frog and fetal pig.

- The purpose of pining these specific part of the organism to the dissecting tray is to allow the organism’s body to stay in place during the process of dissection. It also provides a clearer view when observing the organism internal
