Genetic Bottleneck

The Bottleneck

Genetic research has found that about Seventy thousand (70,000) years ago an event occurred that led to all existing humans now on the earth being genetically related in so far as we have a common ancestor dating from this period. The area this common ancestor came from has been identified as North East Africa.

There have been many theories put forward to cover this situation including.

A disease that wiped out almost all the humans on earth and the human race was subsequently repopulated by a small immune group.

A natural event that killed off almost all the existing human population world wide and the human race was subsequently repopulated by a small surviving group.

A great advancement in warfare in a small group from North East Africa that led to world domination by conquest by this small group and its descendants. Interbreeding led to the common genetic link.

Intervention by god. He destroyed all existing people, maybe by a super flood and sent a small group he saved to repopulate the earth.

For the following reasons most of the above can be discounted. Number 4 however is interesting. It covers the genetic requirement and cannot be disproved as its basis is in faith. However the outcome may be able to be scientifically proved. This will not of course prove the existence of god but a natural event could be the answer.

However the common genetic link seems to have been established.

Dominant Intelligent Gene Theory

A theory that I have come to develop for many reasons is the “Dominant Intelligent Gene Theory” Here I postulate that the Genetic Bottleneck is caused by the spontaneous generation of a gene that gives an increase in the inelegance of the bearer of this gene and that this gene is a dominant gene. This means that in a new baby that inherits this gene from one or both of the parents that so long as there is one copy inherited then the baby also inherit the benefits of the gene. In the case of the Genetic Bottleneck the gene would have to have given a very great dominance for it to have the effect that it subsequently had on the total human population. I initially thought it would have to have been a super inelegant gene however I believe I have identified exactly what this super inelegant gene gave to those that inherited it.

Talking Animals

In the latter part of the 20th century many very interesting experiments were carried out in new directions. Among them in USA was the teaching of a gorilla and a chimpanzee in independent situations sign language. These apes proved to be able students and quite quickly learnt a rather large and sophisticated vocabulary. Their ability to communicate even abstract thoughts was surprising. When introduced to each other they communicated at an advanced level. The language not only led to the above results but seems to have led to a very marked change in the behaviour of these animals. For example the gorilla has had several pet kittens. This behaviour is I understand unique.

These experiments led to the reassessment of what it meant to be human. It seems that intelligence and self awareness is not limited to humans. It would seem that our ability in these directions is one of degree rather than a unique ability.

Other animals have been taught to talk. There is the case of the African Grey Parrot that was taught a large vocabulary and seems to understand the true meaning of many words. Communication between the parrot and humans has been speculator but rather limited. In another experiment a chimpanzee baby was bought up in a family with a similar aged human baby. The Chimp physically developed fasted than the human and in the earlier stages their mental development was similar. However at about eighteen months the human baby started to develop speech and the chimp started to intellectually fall behind. The Chimp never developed to this stage.

The Development of Human Babies

Human babies seem to be born earlier in their development that other mammals. Probably about one year earlier in their development that other mammals. The apes also seem to have this but to a lesser degree. It has been postulated that this is a natural development to allow for the birth of babies with extra large brains and thus heads. It has also led to the very long term commitment by human and to a lesser degree the apes, for the rearing of their children. They remain dependent on their parents for an extraordinary long time.

Recently a group has been established teaching parents to sign to their babies. It has been found that the babies have an ability to communicate from the very early age of about six (6) months. This communication method develops until the babies start to talk and then this form of communication supersedes the signing.

Main Requirements for Intellectual and Physical Domination

It would appear that arguably the most important factors that give humans their advantage over all other animals can be limited to three main original points and later in their development a fourth. Two of these three points occur in many other animals but to date the three are only present together in the modern human population.

They are;

The ability to physically manipulate their environment (hands) High inelegance (Including good memory and an advanced ability to learn.) Advanced communication (speech) Travel

The Apes have the first two. Sea mammals have the second and third. Some birds seem to have the third and fourth. Many animals, eg elephants, dogs, horses, have the second Only man has all three as natural attributes and in the past thirty thousand (30,000) years has gained the fourth.

And it was the Genetic Bottleneck that gave us the third. This became the defining moment when we truly became modern man, (Homo sapiens sapiens). The Genetic Bottleneck gave man the ability to develop advanced communicate with sound, (speech). Before this there could well have been, and probably was, limited audio communication much the same as the existing apes and monkeys. More advances were to occur in man, and should continue to occur, but here the dye was cast. Intelligent man had arrived. It took this super inelegant gene about 30,000 years to spread throughout the Homo Sapiens People. Shortly after this the last of the competing races of Homo died out, unable to compete with their more advantaged cousins.

It may well be that there were races of man on the earth at this time that never had the ability to either crossbreed, or if they could crossbreed, accept the benefits of the new gene. One of these races seems to have been Neanderthal. Even though it seems, they were faster, stronger, had a larger brain, seemed so much better to survive that their less well endowered cro magnon they were to die out. Could it be that they never received the benefits of the third requirement? If this were true they were as doomed from this point as any tribe or group of cro magnon that never received this super inelegant gene. It is not brain size alone that gives this ability but rather the hard wiring of the brain. If this step never occurs then brain size alone will not compensate.

Technology has given us huge advancements in all four categories; in fact it can be argued that technology gave us the fourth. Boats gave us the first ability to travel across what were previously impassable barriers. This led to a rapid population of the last remaining large land areas, Australia and the Americas. With the exception of smaller scatted islands and the South Pole all the land on earth was now home to the modern human.
