The Journey of Man

It has long been debated both in religion and in science about the origin of man . One cites that man was created out from the flesh of some higher Being while the other has many theories regarding such issues But whatever the most possible theory might be , there is no denying that over time , scientists have established a

profound link between the genetic composition of man and how he has evolved over time

In his latest book , Spencer Wells tries to trace our evolution up to our very first ancestor . This book tried to answer some long-standing anthropological questions regarding the origin of humans and we were able to migrate . To answer and trace this , he relied heavily on science specifically the modern techniques and developments in DNA research for support . He basically reiterated that the Y chromosome (that of the male ) is the unaffected marker of the human heritage ADDIN EN .CITE Wells20041 116Spencer Wells The Journey of Man : A Genetic Odyssey2402004Random House Trade backsht tp /www .amazon .com /Journey-Man-Genetic-Odyssey /dp (Wells , 2004 . From that basis , he worked backward through time and concluded that the earliest man can be found in Africa who lived between 31 ,000 to 79 ,000 years ago which he then called the Eurasian Adam . As time goes by , a subsequent population would grow and become isolated from its fellows who then gain new genetic markers that subsequently created a new (genetic ) map in time and space . He also said that the first modern humans left Africa only 2 ,000 generations ago ' ADDIN EN .CITE Wells20041 116Spencer Wells The Journey of Man : A Genetic Odyssey2402004Random House Trade backsht tp /www .amazon .com /Journey-Man-Genetic-Odyssey /dp (Wells , 2004 ) who speedily crossed out to Asia , Europe and America . Utilizing the same indicators he was quick to debunk the notion that the Neanderthals are our ancestors . Moreover , in this book , he was able to find unusual links between faraway peoples (which were not specifically named in the book and was able to give evidences that all Native Americans can be marked out from a group of at least a dozen people . Throughout the book , he was able to elaborate his terminologies and methods which made the human tree seem easy

The book thus has compelling arguments with regard to the origin of man . Wells explicitly argued (and as can be seen from the title itself that the origin of the human race is that of man but he did not trace any blood samples of that of a woman . In lieu with this , a question may arise as to where was the origin of women per se come from . In regard to this argument , Wells did not give any hard evidences . Although his primary goal was to find the original male , the real revolution that he was able to illustrate is racial in nature . Racial in a sense that he was able to find links (no matter how odd it may seem ) regarding the origins of certain populations today . But , as he elaborates further in the book , he stresses that what makes us distinguished form each other are purely cultural and not solely based on our biology

Moreover , the author utilized a new kind of archeology in his research And this archeology does not dig into remnants or fossils but into human cells and genes . Accompanied by his revolutionary techniques , the author was able to give revolutionary details and insights as to where we came from and how we were able to migrate , our origin and more importantly our races . With the numerous advancements that science and technology were able to develop , it is quite commendable in the author 's part to attack his research in a refreshing and more scientific approach . He is praiseworthy because he was able to apply his expertise and at the same time , use new methods that proved to be very successful and reliable Instead of going through the conventional way of finding the origin of man , he was quick to turn to genetics to answer his queries . And thus he was able to come up with new theories and some new arguments . It also helps that his arguments is backed up by his data by his own researches Through this , he was able to refute ideas of some anthropologists who claimed that varying human races were subspecies that had its origin from different regions at different times . This further hardened by diagrams and maps that the author provided

Maybe one of the more underrated s included in the book was how our languages was spread . The author also gives us an idea how language was able to spread and evolve . Much like migration and mutation language evolved from the addition of new genes throughout time Analogous to the trail of how the Y chromosome has lead its way out of Africa , Wells says that language encountered that same route but as we develop a new culture , our respective languages are dying at a very fast rate . This means that the original language that we new are added with new meanings and it is slowly using its original sense but this kind of evolution is not something to fret about for it only signifies that change (good change for that matter ) is constant . As new gene line-ups are added to every race and culture , so as the evolution of language is inevitable . Therefore , culture then is still a major factor to the growth of the race

There are many new and refreshing take that one can find in this book The author clearly gives us a new perspective and arguments regarding our origin . But , unlike many other theories where more questions arise this book tries to answer its own (and other queries as well ) questions The author had the Y chromosome as his basis for tracking down our ancestors and he employed the latest in genetic mapping which proved to be very successful and reliable . It is also of good importance to note that not only does the author focused on the Y chromosome per se but also on how it migrated and its direction which implies the migration pattern of the first humans and their journey to the outside world Moreover , the author also added how language came about its development and evolution throughout time . Lastly , as from the book itself , races were formed from the influx /addition of new line of genes and the environment as they travel through different lands . As humans move from one place to another , they met other people that mostly added to their culture . And perhaps the most startling statement from the author is his argument that races does not exclusively came form genes but importantly , environment and culture were additional factors that contributed to the growth and development of races that we know today References
