Coral Reef

My favorite biome is the Coral Reef.  It is defined by its collection of calcium carbonates that make up coral.  Several animals are dependent on this coral and make their homes and their diets from their byproducts.  This is a very fertile biome and is home to a large variety of species.  Still this biome is very delicate and can be destroyed by several forms of water pollutants or natural disasters.  This marine biome is defined by the presence of coral and all the associated species.  It is a good indicator of the water quality in the ocean area and is very dependent on the location and depth of the ocean.  Several unique species of marine life depend on this biome to survive.   

Favorite Organism and Ecological Niche

Favorite Organism and Ecological Niche

 

My favorite organism is the Panda Bear from central western and south western China.  The panda bear needs several things to survive in that area such as a regular source of water, a large enough area to prevent confrontation between the bears but close enough to other pandas to mate, clean air, and a minimal amount of predators in their area for their young to grow up safely.  All these things are relatively common features for every animal and are included in most ecological niches.  The feature that makes the panda bear’s ecological niche specific to them is bamboo.  Each panda bear eats about 25 lbs of bamboo every day.  It is the primary feature in their diet and each one of them needs to be able to have access to the food they need to survive and procreate. 

Mitochondrial Eve

When people migrated away from Africa to the different climates around the world several of them evolved to fit their new location.  Essentially characteristics that helped a person survive in that climate were more likely to show up in the offspring that were genetically successful and would multiply with the success of that trait.  Features that did not aid in the survival of the organism would likely disappear like the pigment in the skin and hair of the northern people.  Soon the physical appearance of the human race will go back to a more centralized look as a result of globalization.  The physical appearances will again begin to resemble Mitochondrial Eve. 

This is an image of what Mitochondrial Eve could look like.  She has dark hair, eyes , and a medium pigment in her skin

This is an image of a northern person who lived in the arctic region where there was little sun and no need for pigment in the skin, eyes, or hair

 

This is an image of an individual descended from northern dwellers where there was little sun and no need for pigment in the skin, eyes, or hair

 

This is a picture of a historic northern African who has a thin bones structure and is relatively tall

This is a picture of a historic southern African who is more compact and muscular with dense bones.

        

This is a picture of someone with Asian descent who has similar pigmentation to those of Native American origin like this person and Hispanic people like this woman.  Both these people are in climates similar to that of Mitochondrial Eve and as such look similar to how she may have looked in accordance to hair, skin, and eye color, yet they look completely different in their more refined features.  This proves that even evolution can make some people have similar obvious features but still allow them to look remarkably different.
