Paternity and human sexuality


According to the evolution of life, mammals are the most advanced creatures. Human beings are the most advanced creatures among mammals. Human beings are being different from other creatures by their advanced human features. Paternity is one of most advanced human features that we can recognize. Unlike in other animals paternity is an essential thing of human society.
                          Most of animals have a special period of reproduction. Mating male and female creatures and breeding are happening within this particular period. Female creature bears the kids and nurtures until the kids are grown enough to procure their requirements for the persistence. In most of animals this thing is common and no need of male creatures for kids to grow up. Because of the psychological factor of sex in most of animals is not complex. Growing physically and become sexually matured are just enough for completing their life cycle.  But in human beings, the psychological factor of sex is a complex.  Mothers cannot develop the sexuality of boys psychologically without fathers. Because of masculine gender is a paternal inheritance. Psychological masculinity of males is heavily depending on the masculine gender specifications of their fathers. According to the evolution of human beings, paternity is a feature which developed by the nature just because of the requirement of developing entire male sexuality. We cannot simply ignore this fact when we are talking about the evolution of human sexuality. We have to approach a new way of thinking for understanding the truth about human sexuality.

Evolution and the sexuality





The purpose of sexuality is reproduction. There are non sexual reproduction methods can be identified among simple beings and as well as within the world of plants.
However when the evolution of beings becomes advanced, Sexual reproduction method has promoted well and it became the dominate feature. As a result of transforming beings towards a progressive path, the world of creatures appeared. The world of creatures is superior to the world of plants. Dominate feature of the sexuality of plants is hermaphroditism. But within the world of creatures, unisexual creatures are the dominate group.  And the reproduction method also limited only to sexual reproduction within the world of creatures.
                        In the primary stages of evolution, the method of reproduction is simplex even though it is sexual reproduction. Male and female sex differentiation was also simple and that was only for generate the gametes. Most of simple beings were aquatic. Fertilization between simple male and female gametes occurred. When the creatures become evolutionally advance, the sexuality become advance too. The reproductive organs and tissue became complex. Growing the embryo inside a womb is the most advanced feature of reproduction. External genitals which can be well recognized were appeared. External genitals and the internal reproductive organs are pre determining by the sex chromosomes, so the genetic sex determination has taken the priority. Biochemical functions such as actions of sex hormones are also important in sex determination.
             One group of sex, either male or female is dominating the whole species of creatures. The capability of interact with the natural environment more actively is the fact of determining that. Dominating of male creatures is the most recognized feature. Female domination is rare and it is not evolutionally advanced. Mammals are the most advanced creatures in evolution. At last human beings are evolutionally superior to all other creatures. Human sexuality is more advance and it is complex too. Most outstanding feature of human sexuality is the psychological factor and this is known as gender. Physical and genetic factors of sex are common for both human beings and other creatures. If we considered about the hominid evolution, there can be identified a special path of psychological transformation. Human beings created cultural environments and civilized due to this reason. In any culture, gender specifications are conspicuous. Human beings are wearing clothes and this feature is unique to human beings. In any culture there are specific male clothes and specific female clothes. Gender specific human activities can be identified within any culture and they are common. Finally all of these specifications are for better attraction between two sexes. Matching up male sex drive and the female sex drive is an important and essential part of any civilization. Advanced gender specifications are advanced in evolution too.

The long term solution for environmental problems




If there is an environmental management which is more successful, there should be a non destructive way of resource utilization. Gross utilization and higher wastage of every kind of resources will lead to destroy the environment too. Industrialization without any standard is the biggest reason for this situation. However some countries have industry centric economical systems. These economical systems are basically targeting the commercial goals. So the commercial goals are more important than the environment to the people who are depending on the industrial economy. However if we really hope to protect the environment, this situation must change.
            The best alternation is replacing the industry centric economical systems with agriculture centric economical systems. With the agriculture it is easy to manage the environment more efficiently without destroying. On the other hand food is a major requirement, so the agriculture is an essential part of any economical system in any country. And it is possible to maintain other industries with the agriculture, also with a proper standard. However this cannot be an easy task.
            First we must study again about how the world was changed after the industrial revolution. And also we have to research whether the way of changing the world can totally accept or not. It is clear that the people who lived in Europe in 18th century when the industrial revolution is beginning were not thought of protecting the environment. They just wanted to establish and develop industries. The present generation has to take all the things which are happening as a result of the mistakes done by the past generations.      
             If we can control our selves, we can give the priority to protect the environment rather than giving priority to the commercial goals. To do this we have to control our minds. So we have to teach the future generation to live close to the nature and understand the value of natural environment. Then the future generation will control the industrialization with a proper standard. And they will be more sensitive to the environmental values.

Science, Technology and the nature

Science and technology are not there for fighting against the nature. Some people are thinking that they can use the technology as a weapon to fight with the nature. First of all we must have the ability to manage the property of natural environment. There are lots of things which are in the natural environment for the persistence of human beings. Sun light, natural water cycle, earth, soil and plants are there for better life and long time existence of both human beings and animals. The reality is there must be a technology for managing these resources. Science is not only physical science and its related things. If we can manage these things which are in the surface of the earth well, no need to excavate it hard.
