EVERYDAY SCIENCE

Detailed explanation-1: -They can teach us where life and humans came from, show us how the Earth and our environment have changed through geological time, and how continents, now widely separated, were once connected. Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments.

Detailed explanation-2: -Fossils are direct evidence of evolution. It tells about the life found on ancient earth. By studying fossil records palaeontologists reveal the connecting link between different organisms of the past and present. The fossils present in the different layers of earth determine the age of the organisms.

Detailed explanation-3: -Scientists use a technique called radiocarbon dating to find out the age of the fossils. Once they know the age of the fossil in the rock, they also know that rock itself is about the same age! The location of fossils in rock layers provides evidence of Earth’s past landscapes. It is hard to guess the age of rock.

Detailed explanation-4: -Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species.

Detailed explanation-5: -A fossil can tell us the color of an organism, its favorite food, and the age of the organism. A fossil provides evidence about the approximate size of an organism, its living location, and the conditions that an organism lived in.
