1. Yes!!! Guyana is known to have one of the highest biodiversity in the world! Having 1168 verberate species and 1600 different types of bird speices, and also the richest fuana. The Guiana Shield region has been said to have an extremely rich biologically. 70% of natural habitat remains prestine. Guyana also is known for its tropical rainforests that have a high different range of biodiversity.
 * Are there any hotspots of biodiversity?**

2. Yes. From my knowledge, the continents were once one big giant continent called Pangea. Millions of years later Pangea broke apart seperating some continents. Particularly Africa and South America. When looking at both the continents edges they fit together like a puzzle piece. And Guyana is located on the coast of South America, meaning it has fossils and evidence from animals/bacteria found when the contients were one. So their is plently of fossils to see the change in rock.
 * Has any evidence of evolution been found? Describe it.**

3.Well the weather on a normal day in Guyana is hot and humid, with a humidity rate of 100%. Temperatures in Guyana usually stay the same, and since it is a smaller country the weather and climate throughout Guyana is usually the same. This type of climate conditions are really good for rain and rain is good in tropical forests. Tropical forests lead to having a large variety of biodiversity, which is caused by natural selection! Having a stable climate throughout the year keeps natural selection to keep occuring at a normal pace.
 * What climate conditions have influenced the natural selection in the major biomes?**
