In most animals, this is essentially a sperm-centred process of evolution. The integrity of genetic replication during sperm production is often compromised in the course of a male’s lifetime, providing many chances to pass on genetic mutations. The female produces relatively few eggs and does so only for a short period of time, providing much less genetic variety through mutation. The female’s contribution to evolution is considered possible through sexual selection. The theory is that, through the process of natural selection, sensory faculties have evolved which work in conjunction with the nervous system within the unconscious processing centres of the brain. This enables the animal to further its chances of survival by sensing and, through the unconscious, being compelled to procreate with the fittest mate. Evolution, in this case, is driven by instinct, which is a product of evolution.

There are many problems with this theory, the primary objection being the self-referential or self-fulfilling argument. The interpretation of observations that leads a scientist to formulate a theory cannot entirely be separated from his or her instinct. If, as the theory goes, an animal may be driven to procreate through instinct, then surely a scientist can be driven to formulate a theory through instinct. If humans reside in a civilisation wherein a primary instinct is to be the fittest, this would provide the frame of reference for many of their cultural ideas and scientific theories. There are alternative frames of reference.

Hypothesis


I would like to propose an egg-centred process of evolution, which I will call ‘natural design’. The proposed process is not singular; it is composed of a multitude of genetic processes. From the outset I would like to distinguish this theory from both natural selection (1) and intelligent design. Firstly, this is a theory of evolution that attempts to explain how species adapt and develop new functions through genetics. However, it is not related to the notion of selection, whereby the fittest survive and procreate. In this hypothesis, evolution takes place through processes that are subject to the laws of nature (chemistry, physics and biology) – evolution happens by design according to nature. Secondly, I am not attaching intelligence to the design. I am suggesting that nature may have determined particular courses of genetic development, not through intent, but through the activity (or reactivity) of matter, including genetic matter, that is governed by the physical and chemical laws of nature.

Every good hypothesis begins with a good question. Hence, what determines the genetic make-up of the single-cell embryo after the egg has been fertilised by a sperm? In other words, what is the process by which two parents’ DNA merge into one? Scientists have found it impossible to predict the outcome of the merging process because of its chaotic nature. From chaos theory we understand that the apparently random outcomes of nature are not, in fact, random. The outcome is indeterminate because of the complexity of nature (which is composed of a multitude of processes) and in particular a highly sensitive dependency on the initial condition (e.g. initial temperature and initial composition). Very small changes in the initial condition lead to far and away, random-appearing outcomes.

Even though the process of DNA merging in the egg is subject to chaos, let us imagine some of the processes involved and the effects of environmental conditions. Firstly, genes are chemical compounds, just like any other chemical or biochemical (natural) compounds. They are subject to the same physical laws of nature as any other compounds involved in chemical reactions. Part of the process of merging the two sets of DNA, therefore, involves the formation of physi-chemical bonds, and therefore gene clusters (complexes) within the product DNA. If the kinetics of this process is sufficiently fast, we can apply the laws of thermodynamics (2). Secondly, any two genes may have originated by evolution in completely different environments (parts of the world or times in history).

What are the thermodynamic rules for the attraction of compounds with significantly different chemical and other potentials? A strong bond may form to enable the two potentials to coexist and provide new function. If a bond between two genes is extremely strong, it may lead to the recession (condensation) of other genes. Thirdly, foreign compounds in the environment may be involved in the chemical reactions. For example, a virus in the egg may become part of the product DNA (could this lead to immunity?). Fourthly, environmental temperature and other factors would directly impact on the products of the gene reactions by Le Chatelier’s principle – a Lamarckian notion of evolution. Fifth, and not last, and not least, the emotional and physical condition of the mother when the egg is fertilised would affect the baby’s DNA

Spermatogenesis

yes the process is spermatogenesis
the spermatogonium gives primary spermatocytes, which undergo meiosis-1 and give secondary spermatocytes which undergo meiosis 2 and give rise to spermatid which finally develop to sperms
