Discovery of the Largest Orbweaving Spider Species: The Evolution of Gigantism in Nephila
There are more than 41,000 spider species in the world that we know of. Around 400-500 are added to this list each year. The giant golden orbweaver is dated back to the 19th century. They are known to be the biggest orb weavers. These orb weavers are called Nephilia. The females have increased in size. This is useful to them because they are hunted less, and are more capable of protecting the baby spiders.

Humans have been around in the beginning of Pleistocene in the world. The first humans were made about 7 million years ago. The scientist found 14 species, of which are known as Australopithecus. They were 1-1.5 meters tall. They walked upright, had a protruding jaw, prominent eyebrow ridges and a small brain case. The difference from humans now are that we are taller and do not have fur anymore. We do not have a tail anymore, and we do not need out appendix anymore.

The Evolution of Dinosaurs
Dinosaurs are a great example of Evolution for many reasons. One reason is that they show many differences between one another. Theses differences were created to help them with the different environments that they live in and have to adapt to. Examples of these are all the different types of dinosaurs including ones that only eat meat and ones that only eat vegetation. Theses are called herbivore and carnivores. Dinosaurs also have different skin colors depending on what environment they are trying to survive in. For more information look on Evolution of Dinosaurs.

This Texas Horned Lizard show how evolution occurs by squirting blood out of a gland behind its eye so the predator will think twice about eating it since the blood tastes so bad.
