1.	Question : Define evolution. How does it occur? Describe how fossils provide us evidences in support of evolution
Answer» Solution :Evolution is a gradual process leading to heritable changes over several generations. It occurs due to natural selection, mutation or genetic drift. The preserved traces of fossils help in • establishing EVOLUTIONARY traits among ORGANISMS and their ancestors (homologous structures). • establishing the time PERIOD in which organisms LIVED from the position of fossils in the layer of the rocks • documenting the existence of now-extinct SPECIES that are related to present-day species.
