The list of fossils begins with Graecopithecus, dated some 7.2 million years ago, which may or may not still be ancestral to both the human and the chimpanzee lineage. For the earlier history of the human lineage, see Timeline of human evolution#Hominidae , Hominidae#Phylogeny .
What is a fossil? A fossil is physical evidence of a prehistoric plant or animal. This may be their preserved remains or other traces, such as marks they made in
The fossil record was one of the early sources of data underlying the study of evolution and continues to be relevant to the history of life on Earth. The development of radiometric dating techniques in the early 20th century allowed geologists to determine the numerical or “absolute” age of various strata and their included fossils. The fossil record is a huge collection of fossils that document the history of life on Earth. The fossil record is life’s evolutionary epic that unfolded over four billion years as environmental conditions and genetic potential interacted in accordance with natural selection. It could be likened to a movie recording the history of life across nearly four billion years of geological time. The fossil record shows a staggering wealth of organisms. Surprisingly, most of the organisms of the past were much larger and more impressive than present day animals.
· 3. Does the fossil record tell us the The fossil record of the past 6 million years reveals the transition from chimp-like species with smaller average brain sizes to species that are increasingly human- A fossil is the preserved remains or traces of organisms (plants, animals, etc) that lived in the distant past.

Surprisingly, most of the organisms of the past were much larger and more impressive than present day animals. In fact, the fossil record is evidence for devolution rather than evolution. Layers of Fossils Explained In general, the fossil record is consistent with the developmental order suggested by looking at the characteristics of living species. As such it represents another independent piece of evidence for common descent and a very significant one since the fossil record is a window to the past.
13 Mar 2017 The study of the number and placement of fossils within certain types and areas of rock is known as the fossil record. This record gives us an
fossil record The mineralized remains of organisms and the rock layers in which they are found, showing when and where long -dead organisms lived and how their bodies were structured.
