As he did not believe human beings were apeshe believed this might have been during the Cretaceouscontrary to what is possible given the geologic and evolutionary biology evidence available at the time. On the advice of his colleagues, Hardy delayed presenting the hypothesis for approximately thirty years. Several national newspapers reported sensational presentations of Hardy's ideas, which he countered by explaining them more fully in an article in New Scientist on 17 March Some interest was received, notably from the geographer Carl Sauer whose views on the role of the seashore in human evolution [15] "stimulated tremendous progress in the study of coastal and aquatic adaptations" inside marine archaeology.

An analysis of the human evolution and the water theory

Evolutionary theories continue to generate testable predictions and explanations about living and fossilized organisms. It is based on the evolutionary premise of an ancestral descendant sequence of genes, populations, or species. Individuals that evolve are linked together through historical and genealogical ties.

Evolutionary trees are hypotheses that are inferred through the practice of phylogenetic theory.

They depict relations among individuals that can speciate and diverge from one another. The evolutionary process of speciation creates groups that are linked by a common ancestor and all its descendants.

Species inherit traits, which are then passed on to descendants. Evolutionary biologists use systematic methods and test phylogenetic theory to observe and explain changes in and among species over time.

These methods include the collection, measurement, observation, and mapping of traits onto evolutionary trees. Phylogenetic theory is used to test the independent distributions of traits and their various forms to provide explanations of observed patterns in relation to their evolutionary history and biology.

Evolution as theory and fact in the literature[ edit ] The following sections provide specific quotable references from evolutionary biologists and philosophers of science demonstrating some of the different perspectives on evolution as fact and theory.

Evolution as fact[ edit ] American zoologist and paleontologist George Gaylord Simpson stated that "Darwin If you like, then, I will grant you that in an absolute sense evolution is not a fact, or rather, that it is no more a fact than that you are hearing or reading these words.

Miller writes, "evolution is as much a fact as anything we know in science. How else except by the word evolution can we designate the sequence of faunas and floras in precisely dated geological strata?

And evolutionary change is also simply a fact owing to the changes in the content of gene pools from generation to generation. Writing inbiologist Julian Huxley entitled the third book of the wide-ranging series The Science of Lifewhich dealt with the fossil record and the evidence of plant and animal structures, The Incontrovertible Fact of Evolution.

He also says "Natural Selection There we come to speculative matter, to theories. Stephen Jay Gould writes, " It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Theories are structures of ideas that explain and interpret facts.

Darwin's theory of evolution shook the foundations of Christian doctrine and, more than any other pronouncement since Copernicus placed the sun at the centre of the solar system, brought home to ordinary people the far-reaching consequences of scientific analysis. Jul 26,  · A manifesto from 23 researchers challenges old models, and outlines the major new directions archaeology should follow to solve the puzzling origins of modern humans. Human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.

Facts do not go away when scientists debate rival theories to explain them. Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth.

And biologists have identified and investigated mechanisms that can explain the major patterns of change. That evolution is a theory in the proper scientific sense means that there is both a fact of evolution to be explained and a well-supported mechanistic framework to account for it.A Missing Genetic Link in Human Evolution.

Mysterious episodes of genetic duplication in our great ape ancestors may have paved the way for human evolution. Abstract.

Human cultural traits—behaviors, ideas, and technologies that can be learned from other individuals—can exhibit complex patterns of transmission and evolution, and researchers have developed theoretical models, both verbal and mathematical, to facilitate our understanding of these patterns.

Evolution: Evolution, theory in biology postulating that the various types of plants, animals, and other living things on Earth have their origin in other preexisting types and that the distinguishable differences are due to modifications in successive generations.

It is one of the keystones of modern biological theory. Human evolution. Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.
