Fossils provide information about prehistoric life. Fossils are formed when plant or animal remains become trapped in sediment and slowly turn to stone over millions of years. Fossils can be found all over the world, buried in rock or trapped in amber. Studying fossils helps scientists learn about extinct species like mammoths and how life has changed over long periods of time.

Evolution is the study of changes in life forms over generations. The theory of evolution proposes that all species are related and gradually change over time through a process called natural selection. Evidence for evolution comes from fossils showing changes in ancient life forms, comparisons of anatomy and genes between current and extinct species indicating common ancestry, and observations of natural selection leading to new species. Charles Darwin's theory of evolution by natural selection established evolution as the underlying mechanism for the diversity of life.1307 Animalia f2019

2) It discusses influential figures like Lyell, Lamarck, and Malthus and how their work related to ideas of deep time, adaptation, and limits on population growth.
3) Darwin's voyage on the Beagle and observations of related finch species in the Galapagos informed his later theory of natural selection and idea that species change over generations in response to their environment.Vocabulary hungry little hare
