Answer 1

Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome. Gene and chromosome duplications occur in all organisms, though they are especially prominent among plants. Gene duplication is an important mechanism by which evolution occurs.
The Chimpanzee Genome Project is an effort to determine the DNA sequences of the chimpanzee genome. It is expected that by comparing the genomes of humans and other apes, it will be possible to better understand what makes humans distinct from other species froms a genetic perspective. It will also aid in the study of diseases that affect (or, conversely, do not affect) various primate species .

Before Darwin was born, most people in England accepted certain ideas about the natural world as given. Species were not linked in a single "family tree." They were unconnected, unrelated, and unchanged since the moment of their creation.
