=The Evolution Of Dolphins = Post Number One  October 23, 2015

When most people think of dolphins they picture the happy blue animal performing tricks through ocean on hot sunny days, but where dolphins have evolved from is much different! Dolphins were at one time land animals as were many other mammals that now roam the oceans. These animals had to go through two large changes during evolution, the first starting out in the water. They thenmade their way to land and developed into mammals which very closely resembled wolves. They then started to adapt to swamps and their bodies began to adapt to the water. Their breathing, body shape, and over all appearance has changed drastically over the past 50 000 000 years into the friendly mammal of the ocean you see today. This is a picture of what the dolphin is thought to have looked like on land. This is a picture of what a dolphin looks like today.

This video shows the the evolution of dolphins from start to finish showing images of what these animals are believed to have looked like 50 000 000 years ago to today.

This website gives further explanation of dolphin evolution as well as other facts about dolphins to help with overall knowledge on this species This website shows an animation of the whale evolutions which is very similar to that of the dolphin species. This website explains the evolution of cetaceans as a whole which includes whales, dolphins and porpoises.

=The Genetics Of Taste = Post Number Two November 20, 2015

Do you ever wonder why your favourite food may some ones least favourite choice of snack? Well this maybe because you have different genes that make the two of you taste differently. People that are able to taste PTC (phenylthiocarbamide) may find foods more bitter than those that cannot taste PTC. Scientists figure that this genetic difference started with our ancestors and depending on where they lived. Our ancestors would have had to taste different plants to see if they were poisonous or not and so this trait helped them to survive.

This tongue doesn't have any taste buds. This is an example of an average tongue and the little dots on the tongue, the taste buds, are what tells you what you are tasting.

<span style="display: block; font-family: 'Times New Roman',Times,serif; font-size: 120%; text-align: left;">The pancreas is one of the ten glands in the endocrine system that everybody has. The pancreas is in control of producing chemicals such as insulin, glucagon, and somatostatin which are hormones that regulate the blood sugar in the body. In the exocrine system the pancreas produces different enzymes that help with digesting food. So when the pancreas is not functioning to the best of its ability people may have problems with digestion or they may be a diabetic. <range type="comment" id="571965323_1"></range id="571965323_1">
