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>
Answer: Agriculture created most of Egypt's wealth. Grain, vegetables, fruit, cattle, goats, pigs and fowl were grown, and fish from the Nile were caught, and eventual surpluses, after deduction of the various taxes, were sold on the markets. Thanks to the yearly inundations the soil remained fertile.

1. "Each person is to have an equal right to the most extensive total system of equal basic liberties compatible with similar system of liberty of all."
This is called the <em>greatest equality liberty system</em>. The principle addresses the question of the distribution of rights and liberties. This principle states that each person has the right to access basic liberties in the most extensive way that remains compatible with everyone maintaining such rights.
2. "Social and economic inequalities are to be arranged so that they are both:
(a) to the greatest benefit of the least advantaged, consistent with the just savings principle, and
(b) attached to offices and positions open to all under conditions of fair equality of opportunity."
This second feature is divided into the <em>difference principle </em>and the <em>equal opportunity principle</em>. The difference principle states that certain inequalities can be allowed as long as these benefit the less-advantaged members of society. The equal opportunity principle states that these advantages should be able to be acquired through work that is open to all. Therefore, everyone can have a realistic chance of acquiring them.
