The fossil record provides snapshots of the past which, when assembled, illustrate a panorama of evolutionary change over the past 3.5 billion years. The picture may be smudged in places and has bits missing, but fossil evidence clearly shows that life is very, very old and has changed over time through evolution.

The earliest fossils resemble microorganisms such as bacteria and cyanobacteria (blue-green algae); the oldest of these fossils appear in rocks 3.5 billion years old (see Precambrian time). The oldest known animal fossils, about 700 million years old, come from the so-called Ediacara fauna, small wormlike creatures with soft bodies. Numerous fossils belonging to many living phyla …

Transitional fossils are fossils which are thought to document the evolutionary change, or transition, of one species into another. The orohippus, mesohippus, miohippus, merychippus, and pleshippus are all thought to be transitional fossils, documenting the evolution of the hyracotherium into the modern horse.

Fossils, or rocks with evidence that life, show that life formed on Earth nearly four billion years ago. The fossil record helps scientists to understand the history of change over time. We find fossils such as sea shells, imprints of plants and animals, and burrows from worms that crawled through the soil long before man existed.

15/11/2018 · Evidence of Evolution. Fossils. They are the remains of the non-degraded parts of living beings found within rocks. The layer from which the fossil is recovered decides the age of the fossil. The fossils found deeper down are older compared to the ones found in the upper layers. They give an idea of the condition of the earth in that specific era.

Most of the evidence for human evolution has been found in eastern and southern Africa, and Kenya has produced fossils that tell most of our evolutionary story. However, these fossils are very rare and are often only fragments. There are many fossil sites in Africa that have yielded remains of early man. Kenya is particularly
