Millions of stone tools, figurines and paintings, footprints, and other traces of human behavior in the prehistoric record tell about where and how early humans lived and when certain technological innovations were invented.Study of human genetics show how closely related we are to other , all over the world.Biologists and paleontologists, among others, know this claim is false.As key evidence for evolution and species' gradual change over time, transitional creatures should resemble intermediate species, having skeletal and other body features in common with two distinct groups of animals, such as reptiles and mammals, or fish and amphibians.These animals sound wild, but the fossil record — which is far from complete — is full of them nonetheless, as documented by Occidental College geologist Donald Prothero in his book "Evolution: What the Fossils Say and Why It Matters" (Columbia University Press, 2007).Prothero discussed those fossils last month at the American Museum of Natural History in New York, along with transitional fossils that were announced since the book was published, including the "fishibian" and the "frogamander."At least hundreds, possibly thousands, of transitional fossils have been found so far by researchers.This method helps to connect fossils found at different location in similar rock.By using a marker fossil, usually an organism with a hard shell, a chronology of fossils can be made.
The older the fossil, the deeper they are in the rock, The younger fossils are towards the surface.A lot of us relate most to fossils of life closely related to humans, so the list focuses on mammals and other vertebrates, including dinosaurs. Thousands of human fossils enable researchers and students to study the changes that occurred in brain and body size, locomotion, diet, and other aspects regarding the way of life of early human over the past 6 million years.Advances in the dating of fossils and artifacts help determine the age of those remains, which contributes to the big picture of when different milestones in becoming human evolved.Exciting scientific discoveries continually add to the broader and deeper public knowledge of human evolution.
If we look at what coordinates are oriented such minerals at the site, we can associate it with a particular time.
