Matching 2 Tags Series: The Human Fossil Record In this series,
James Kidder provides an intriguing study on transitional
fossils and the evolutionary history of modern humans. He begins
by discussing the fossil record, explaining how new forms are
classified. He then explains the physically distinguishing trait
of humankind—bipedalism. From the discovery of Ardipithecus, the
earliest known hominin, to the australopithecines, the most
prolific hominin, Kidder focuses on the discovery, the anatomy,
and the interpretation of these ancestral remains. Series: The
Cambrian "Explosion", Transitional Forms, and the Tree of Life
Many evolutionary critics have identified the Cambrian Explosion
as a stumbling block to the theory of evolution, arguing that
the “expected transitions between major invertebrate phyla are
absent, and that the suddenness of their appearance in the
fossil record demonstrates that evolutionary explanations are
not viable.” Keith Miller argues that the Cambrian Explosion is
not so problematic a
