Evolution isn't a steady process. When the environment changes, the organisms have to adapt quickly or perish. A theory known as punctuated equilibrium accounts for this. Any changes in then environment brought on by natural or artificial changes will cause animals to evolve to those changes. It may be that they just have to migrate where the climate is more suitable. When you look at geologic sequences, you can often see the different environments as the climate changed and a new suite of animals and plants took over.
<span>It is fantasy to claim that the "old" environment was stable before humans came along unless you live in the tropics. There was a mile of ice over NYC and Chicago 15 thousand years ago. </span>
<span>Geologic changes can affect evolution by creating population splits which allows for speciation. For example, the thrusting up of a mountain range may cause one population to split into two. The separate populations may then evolve on their own sometimes into new niches. One population may stay relatively similar and the other may change dramatically.</span>
Migrant workers often receive remittances, or monies from their home country, to help them while working abroad.

Answer d could be right but sense of humour will be the final conclusion of the study. First, researchers will observe students´reactions (independent variable) which will lead to a more general conclusion; sense of humor affected by the amount of sleep.
Frankly, I think that the motives of the conquistador lies in their name. These men wanted to conquer "the other," that which was in front of them. They did not come in peaceful harmony. Their motives were to conquer and capture that which existed in their path to extolling their own glory, and that of nation in a secondary capacity. The Conquistador use of force through the military reveals that their motives were to control New lands and native populations.
