GEOLOGY

Detailed explanation-1: -The word fossil is derived from the Latin fossilis meaning ‘unearthed’. Preserved evidence of the body parts of ancient animals, plants and other life forms are called ‘body fossils’. ‘Trace fossils’ are the evidence left by organisms in sediment, such as footprints, burrows and plant roots.

Detailed explanation-2: -The fossil evidence definition refers to the evidence of bacteria, animals, and plants that lived in the past. Fossil evidence is used to determine what the organism was, when it lived, and what major events it experienced during its lifetime.

Detailed explanation-3: -Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.

Detailed explanation-4: -Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.
