Human evolution - Human evolution - The fossil evidence: By 3.5 million years ago at least one hominin species, Au. afarensis, was an adept walker. In addition to anatomic evidence from this time, there is also a 27.5-metre (90-foot) trackway produced by three individuals who walked at a leisurely pace on moist volcanic ash at Laetoli in northern Tanzania. In all observable features of foot.
While fossil evidence alone does not prove that all life forms are related by common ancestry, the fossil record is consistent with (and highly suggestive of) that conclusion. Predictions about where transitional fossils should be found—made on the basis of common ancestry—have yielded stunning discoveries. For Christians, the fossil record is a remarkable gift that prompts reflection on.

A transitional fossil is the remains of an organism that is thought to be an evolutionary link between two distinct groups. This is suggested when the organism possesses characteristics that uniquely belong to different taxonomical groups, or.

Argument 6: Evolution is confirmed by the fossil record Very few fossils had been discovered at the time of Darwin's original thesis, but it was clear from the theory that, if evolution is true, fossils of simpler forms of life should be found at earlier or lower levels of strata of the Earth and fossils of more developed forms of life should be discovered in later or higher levels of strata.

This brief essay presents a definition of evolution that is acceptable to evolutionists. Evolution is a Fact and a Theory Biologists consider evolution to be a fact in much the same way that physicists do so for gravity. However, the mechanisms of evolution are less well understood, and it is these mechanisms that are described by several theories of evolution. The Modern Synthesis of Genetics.
Perhaps one of the most important functions of fossils from a scientific perspective is that they constitute one line of evidence for understanding evolution. Using information pieced together from fossil evidence, scientists can reconstruct body types of animals that no longer exist and put together a “Tree of Life” to describe the evolutionary relationships between organisms (reference 3).
