An introduction to the origins of mankind

The modern theory concerning the evolution of man proposes that humans and apes derive from an apelike ancestor that lived on earth a few million years ago. The theory states that man, through a combination of environmental and genetic factors, emerged as a species to produce the variety of ethnicities seen today, while modern apes evolved on a separate evolutionary pathway.

Perhaps the most famous proponent of evolutionary theory is Charles Darwin who authored The Origin of Species to describe his theory of evolution. It was based largely on observations which he made during his 5-year voyage around the world aboard the HMS Beagle Since then, mankind's origin has generally been explained from an evolutionary perspective.

Moreover, the theory of man's evolution has been and continues to be modified as new findings are discovered, revisions to the theory are adopted, and earlier concepts proven incorrect are discarded.

Evolution Of Man - Concepts in Evolutionary Theory The currently-accepted theory of the evolution of man rests on three major principles. These principles hinge on the innate ability which all creatures have to pass on their genetic information to their offspring through the reproductive process.

An alternative explanation for homology is a common designer. The first tenet is microevolution, the occurrence and build-up of mutations in the genetic sequence of an organism.

Mutations are predominantly random and can occur naturally through errors in the reproductive process or through environmental impacts such as chemicals or radiation. The second tenet of evolution is natural selection. Natural selection is a natural mechanism by which the fittest members of a species survive to pass on their genetic information, while the weakest are eliminated die off because they are unable to compete in the wild.

Natural selection is often termed "survival of the fittest" or "elimination of the weakest. The new population becomes a reproductively isolated community that is unable to breed with its former community.

Through speciation, the genes of the new population become isolated from the previous group. Evolution Of Man - Scientific Evidence The theory of evolution of man is supported by a set of independent observations within the fields of anthropology, paleontology, and molecular biology. Collectively, they depict life branching out from a common ancestor through gradual genetic changes over millions of years, commonly known as the "tree of life.

This causes a growing number of scientists to dissent from the Darwinian theory of evolution for its inability to satisfactorily explain the origin of man. One of the major evidences for the evolution of man is homology, that is, the similarity of either anatomical or genetic features between species.

For instance, the resemblance in the skeleton structure of apes and humans has been correlated to the homologous genetic sequences within each species as strong evidence for common ancestry.

This argument contains the major assumption that similarity equals relatedness. In other words, the more alike two species appear, the more closely they are related to one another.

This is known to be a poor assumption. Two species can have homologous anatomy even though they are not related in any way.

This is called "convergence" in evolutionary terms. It is now known that homologous features can be generated from entirely different gene segments within different unrelated species. The reality of convergence implies that anatomical features arise because of the need for specific functionality, which is a serious blow to the concept of homology and ancestry.

Additionally, the evolution of man from ape-like ancestors is often argued on the grounds of comparative anatomy within the fossil record. Yet, the fossil record indicates more stability in the forms of species than slow or even drastic changes, which would indicate intermediate stages between modern species.

The "missing links" are missing. And unfortunately, the field of paleoanthropology has been riddled with fraudulent claims of finding the missing link between humans and primates, to the extent that fragments of human skeletons have been combined with other species such as pigs and apes and passed off as legitimate.

Although genetic variability is seen across all peoples, the process of natural selection leading to speciation is disputed. Research challenging the accepted paradigm continues to surface raising significant questions about the certainty of evolution as the origin of man. Evolution Of Man - The Scrutiny The theory concerning the evolution of man is under increased scrutiny due to the persistence of gaps in the fossil record, the inability to demonstrate "life-or-death" determining advantageous genetic mutations, and the lack of experiments or observations to truly confirm the evidence for speciation.

Overall, the evolution of man pervades as the accepted paradigm on the origin of man within the scientific community. This is not because it has been proven scientifically, but because alternative viewpoints bring with them metaphysical implications which go against the modern naturalistic paradigm.

Nevertheless, a closer examination of the evidence reveals evolution to be increasingly less scientific and more reliant upon beliefs, not proof.(c) R.

This definition encompasses small-scale evolution (changes in gene — or more precisely and technically, allele — frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations).

Evolution helps us to understand the history of life. "Zoroastrianism is the oldest of the revealed world-religions, and it has probably had more influence on mankind, directly and indirectly, than any other single faith.".
