Coevolution in News

Co-evolution between humans, bacteria reduces gastric cancer risk, research suggests

• Colombian villages and found that if you have Helicobacter pylori bacteriadepends the risk of gastric cancer caused on both the ancestry of the person and the ancestry of the microbe they carry. Half of the world's population is injected with H. pylori. but only minor gastric problems. Gastric cancer is the second caused death in the world.

Questions:

1. What are the two places in Columbia Williams Research team studied?
2. Which ethnicity were you if you had the H. pylori disease?
3. What is the relation between ancestry and H.pylori?
4. How does co-evolution play a part in this disease?
5. Why does Dr.Jay Dunlap think that, "These data provide a remarkable example of coevolution between humans and the natural world; in particular, the microbial environment,"?

Evidence of Evolution and Coevolution

Evolution- the process by which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth.

Co-evolution- Change in one species in the course of the change of another happening. They are completely depended upon each other. 

Examples:
-The pollinator gets a reward such as nectar for pollinating the plant. (Co-evolution)

• Butterflies
• Moths
• Bees

-Moths on Orchids (Co-evolution)
-Butterfly on Plants
-Pesticide Resistant Insects
-Peppered Moth

Greenhouse Effect

http://education.nationalgeographic.com/education/encyclopedia/greenhouse-effect/?ar_a=1
Recently in our class we have been discussing the greenhouse effect. The greenhouse effect is the trapping of the sun's warmth in the lower atmosphere. The greenhouse effect keeps the earth warm enough so it can sustain life. Some greenhouse gases come from natural resources such as evaporation, swamps, and volcanoes. The Industrial Revolution is the birth of the releasing of larger amounts of greenhouse gases at start. Now the CO2 in the air does not compare to that of a time long ago such as 650,000 years ago.

Extinctions

Massive Extinctions From Human Activity	Value 1 Aesthetic	Value 2 Environmental
Short Term Consequence Positive		More Urban Growth.
Negative	Climate Change within the extinctive animal habitat.	Invasive alien species.
Long-Term Consequence          Positive
Negative	Habitat loss and degradation.	Excessive nutrient load and other forms of pollution.

The numbers of endangered animals is 10x the previous number because of human action that is brought upon them.

• Pollution in Hawaii causes animals ,such as Sea Turtles tumors. 
• It coincides with the reef ecosystem and how everything and the sea life animals relate to it.
