I would think that an unweathered rock would be jagged while a weathered rock would be smooth because of water/wind or what ever weathered it.
A tarsier, although a primate, is not an anthropoid. Examples of anthropoids are humans, orangutans, and gibbons. The speciation that happened between the small primate and the anthropoids was 65 million years ago. It was during that time that the common ancestors of all primates were still alive.
The answer would be C, The rising of global temperatures, why?
Well, global warming means that the worlds temperature is rising.
So, rising global temperature is solid evidence the world is warming up.

Ecological balanced refers to the condition of dynamic equilibrium in a community of organisms in which the species, the diversity of ecosystem and the genetic pool remain relatively constant as a result of gradual changes that are brought about by natural selection. It is very important to ensure that the natural balance in an ecosystem is maintained. Typically, an ecosystem has to move through series of successional changes before it can reach the state of equilibrium. FOR AN ECOSYSTEM TO BE BALANCED, IT WILL TAKE BETWEEN THIRTY TO ONE HUNDRED YEARS depending on the type of ecosystem involved.
