Nature is extremely efficient and mainly manages that by timing . Since reproduction is the main goal of evolution in every living organism, timing also plays the main part im managing that. Reproducing at the wrong time can be disastrous to the specious. The offspring must grow fast to improve their chance of survival and reproduce before they die. The timing of birth is also crucial because food being scares in nature with a lot of competition for it, the timing must be spot on.

Each specious in nature has an in built biological clock. In human it decides when a female is ready to reproduce, when to ovulate and how often. Animals come to heat at the start of breeding season within a week or so. Humans seem to be an exception to this rule because they breed all year round. But that in my opinion only appears to be. Humans just like any other animal must breed as their biological clock dictates.

In the distant past when we lived in small tribes of 150-200 people, the gene pool would be synchronised over the generations. But today the world is extremely dynamic. People live in amongst populations of about 10,000 in to 1,000,000, which they can interact with and also they migrate a lot mixing the gene up pool. It may seem that this has had a dramatic effect on the natural biological clock.

The other factor we must include is that every individual’s ancestor goes back to only a few hundred individuals. If you look around, you see people who have a common feature also have many other similar features. So mixing genes is not as straight forward as it seems. It appears that when animal breed they pass on the successful DNA and not their parents combined. So it means that the all previous ancestors are still competing through the existing gene pool and mixing features of one person with another is not purely random.

This led me to think that if this and the timing theory are correct, every egg and sperm in one person carries a different set of ancestor gene that had also has a specific timing for breeding. That means the egg that is fertilised successfully must be of the ancestor that had that timing for breeding in that time only. Put is simply, if you are born in June for example your gene is very likely to come from an ancestor who was also born in June. The timing gets the precedence. Since those who are not born in June also survive then any DNA can survive but they are of difference ancestors. The other DNA did not take part or failed in the breeding if the fertilisation occurred outside their breeding time.

This means it is possible that almost everyone that is born, or more correctly, their egg and sperm were active during the fertilisation must be have the same common ancestor; therefore they also carry common characteristics. This means this commonality between people born at the certain time of the year could have been subconsciously picked up by astrologers and gave validity to their work. If it turned out to be mostly true, people started believing in astrology more and unfortunately the prediction of the future event took a free ride with it and got mixed up into one.
