With the conquests of the Caliphates, the Muslims managed to take control over multiple regions. One of those regions was North Africa, where in Egypt, in the city of Alexandria there were millions of books with scientific and philosophical themes. It was the center of knowledge of the world in that time.
The Muslims unfortunately destroyed most of the books from the antiquity, and only few were preserved. Thus few though got into the hands of Muslim scholars that were interested in science and philosophy. They read them carefully and started to base their researches on them, making significant progress and discovering multiple things. By preserving these few books, and also upgrading on their basis, helped to preserve at least some part of the ancient knowledge, which later was reintroduced in its place of origin, Europe.

1. The Europeans had very big impact on the New World, unfortunately, it was mostly negative impact on the environment, native people, flora and fauna. The environment was gradually destroyed in order to create more space for farmlands and building settlements. The majority of the native population was treated very badly, and also the diseases brought by the Europeans annihilated their populations. Lot of animals and plants got endangered, some lost most of their ranges, and some even went extinct.
2. The New World's native inhabitants had both positive and negative effect on the Europeans. The positive was that they thought them how to survive in the new environment, as well as introducing them to numerous crops. The negative are the several diseases transferred tot he Europeans, like syphilis, which turned out to be fatal for lot of Europeans. The plants from the New World had huge positive effect, as the Europeans managed to sort out the malnutrition problem with some of them, like the potato, and use others for getting making lot of profit, like the tobacco. The animals of the New World though didn't really had any significant impact on the Europeans, as the Europeans valued the animals they brought much more.
3. The interaction between the Indians and the Europeans managed to create a unique new world in its own way. Despite the relations not being very good, especially at the start, gradually they started to communicate more, share ideas and technologies, teach other different things. Also, the culture that was taking shape had elements from both sides, and in numerous areas the population even became mixed, giving rise to a mixed race, mestizo, which quickly became dominant in what is now Latin America. The adoption of both sides of things that can be useful for further development created a unique way of life, politics, economy.
