<p align="left"><font face="Times" color="#333333" size="4"><strong>The history of biology in a chronological order presented. The aim of the history of biology to let the new learners have a more wider and practical information toward their research in biology. The examination of the history shows that biological development and innovations had a peak at around 1800-1950s in terms of major discoveries on the fundamentals of biological organisms such as the verification of proteins, DNA, cellular structures and other molecules. From 1960s, biology saw a great number of applications and techniques indicating that the academic discipline was moving toward technological and industrial field with explosion of knowlege, interactions with other disciplines and techniques.</strong></font></p>

<p><font face="Times" size="3">The history of biology, before Christ, and before the discovery of genetic inheritance by G. Mendel in 1865, is sketch and inaccurate. Also, there is a significant bias toward the Far Western civilizations. This is partly because the development of biological science overall was a part of every day living for human beings and certain cultures did not regard achievements as historically distinct events. Particularly, the cultures in the East such as China, Korea and Japan had a different philosophy on intellectual properties that caused that not many originators are known. Not only that they regard inventions, discoveries and advancement more as a global social networking, but also officially, there were limited number of social classes who had the right to enscribe names. For example, even if tens of scholars invented the writing system of Korea possibly based on already ancient predessesors, it is regarded as the king who ordered to make it was the inventor. There are numerous such cases. Also, the achievements can survive mostly through cultural interitance rather than well documented books. Furthermore, strong central imperialism often destoryed invaluable books, historical records, momuments and buildings. The fact that the Far Eastern culture was a wood culture while the Far Western was a stone culture contributed a lot in the preservation of historical records. Remaining records are usually by later people who reorganized the older discoveries and developments transmitted through various unsystematic ways. Therefore, it is a reasonable rule of thumb that the known dicoveries in those regions are usually older than the recorded. This is quite contradictory to the Far Western culture where more individualistic and egoistic trends dominiate. The Far Westerners actively take up, mark their names, guard, claim (even steal actively) and preserve the records for scientific and political purposes. It is partly based on the competitive economical and political arena they belonged to. Different monary systems in the Far West provided resource and protection for their own selfish gaines. Sometimes, scientists had to sell their names and technologies to them. It is interesting how the distinct cultural machinery resulted in very different historical understanding of the science, development, society and the world as a whole. The Far Western enterprenuership of promoting their own individualistic, tribal, national, racial, religious and cultural interest as one of the most important sources of understanding the world. While the much more tight social networking of the East rarely encourages the attribution of major achivements to individuals. In a scientific perspective, it is more accurate to attribute the achievement to the whole network of people and resource. However, in a historical point of view, it is more convenient to attribute to individuals. For example, putting the pythagrian theorem to a person's name is more convenient for historians even if the actual work could well have been the collaborative effort of a whole school and surely affected by previous indeas, insights and knowledge orginated from different people. </font></p>
<p><font face="Times" size="3">Therefore, this older part of the history and pre-history should be viewed as a rough guide to show how much ancient people knew about life.The later part where precise names and credits are recorded by modern people also have a lot of controversy. It shows that majority of claims and credits have some kind of disputes. Such disputes on scientific and engineering achievement should be eliminated. A better poligy and paradigm for attributing achiement is necessary in the future. </font></p>

<p><strong><font color="#0033ff" size="4">Methods:</font></strong></p>
<p><strong>Sources</strong></p>
<p>The events are collected from Internet sites, published journal articles, and books.</p>
<p><strong>Precision and Accuracy.</strong></p>
<p>The preciseness of the events are completely dependent on the reliability of the data. For example, the domestication of dogs was very controversal and many Westerners claimed that it was clearly occurred in middle East area. However, recent mitchondrial study showed that it is more likely to be in the Far East. The criterion applied in finalising the data is bases on how rigorous the scientific methods were. MtDNA test is more likely to be accurate than some fossil records and conjectures based on the distribution of sub-species of dogs at present times.</p>
<p><strong>Controvesy</strong></p>
<p>Controversal cases such as the contribution of the development of the idea of gravity by Issac Newton and Robert Hooke is a major problem of the history of biology and science. The political and egoistic influence of individuals in the history is estimated to be tremendous. There can be much wrong data purely some scientists were less interested in insisting on the their own contributions with many reasons such as disgust toward more aggressive and self-promoting ones, lack of interest in such external recognition and pure altruism. Scienctists have been strongly political throughout the history contrary to the general perception of their objectiveness, honesty, fairness and alruistic behaviours by the public. This is partly due to the Western culture's strong recognition on individuals' contribution to the development of humanity. This report's philosophy (the highest level decision principle) is to minimize such bias toward more politically active inventors and scientists. In other words, the most factual data in the widest aspects are sought after. For example, even though Gutenberg's contribution of inventing movable types and printing machine has contributed significantly to the European social, religoius, scientific and political development, he is regarded as an enterpreneur rather than the original thinker or inventor. Recording name for the invention for the humanity will be akin to recording William Gates of Microsoft as the inventor of modern computer operating system (OS) because 99% of the public in China may not know that there were other OSs. </p>

<p align="left"><font face="Times" color="#333333" size="4"><strong>The history of biology in a chronological order presented. The aim of the history of biology to let the new learners have a more wider and practical information toward their research in biology. The examination of the history shows that biological development and innovations had a peak at around 1800-1950s in terms of major discoveries on the fundamentals of biological organisms such as the verification of proteins, DNA, cellular structures and other molecules. From 1960s, biology saw a great number of applications and techniques indicating that the academic discipline was moving toward technological and industrial field with explosion of knowlege, interactions with other disciplines and techniques.</strong></font></p>

<p><font face="Times" size="3">The history of biology, before Christ, and before the discovery of genetic inheritance by G. Mendel in 1865, is sketch and inaccurate. Also, there is a significant bias toward the Far Western civilizations. This is partly because the development of biological science overall was a part of every day living for human beings and certain cultures did not regard achievements as historically distinct events. Particularly, the cultures in the East such as China, Korea and Japan had a different philosophy on intellectual properties that caused that not many originators are known. Not only that they regard inventions, discoveries and advancement more as a global social networking, but also officially, there were limited number of social classes who had the right to enscribe names. For example, even if tens of scholars invented the writing system of Korea possibly based on already ancient predessesors, it is regarded as the king who ordered to make it was the inventor. There are numerous such cases. Also, the achievements can survive mostly through cultural interitance rather than well documented books. Furthermore, strong central imperialism often destoryed invaluable books, historical records, momuments and buildings. The fact that the Far Eastern culture was a wood culture while the Far Western was a stone culture contributed a lot in the preservation of historical records. Remaining records are usually by later people who reorganized the older discoveries and developments transmitted through various unsystematic ways. Therefore, it is a reasonable rule of thumb that the known dicoveries in those regions are usually older than the recorded. This is quite contradictory to the Far Western culture where more individualistic and egoistic trends dominiate. The Far Westerners actively take up, mark their names, guard, claim (even steal actively) and preserve the records for scientific and political purposes. It is partly based on the competitive economical and political arena they belonged to. Different monary systems in the Far West provided resource and protection for their own selfish gaines. Sometimes, scientists had to sell their names and technologies to them. It is interesting how the distinct cultural machinery resulted in very different historical understanding of the science, development, society and the world as a whole. The Far Western enterprenuership of promoting their own individualistic, tribal, national, racial, religious and cultural interest as one of the most important sources of understanding the world. While the much more tight social networking of the East rarely encourages the attribution of major achivements to individuals. In a scientific perspective, it is more accurate to attribute the achievement to the whole network of people and resource. However, in a historical point of view, it is more convenient to attribute to individuals. For example, putting the pythagrian theorem to a person's name is more convenient for historians even if the actual work could well have been the collaborative effort of a whole school and surely affected by previous indeas, insights and knowledge orginated from different people. </font></p>
<p><font face="Times" size="3">Therefore, this older part of the history and pre-history should be viewed as a rough guide to show how much ancient people knew about life.The later part where precise names and credits are recorded by modern people also have a lot of controversy. It shows that majority of claims and credits have some kind of disputes. Such disputes on scientific and engineering achievement should be eliminated. A better poligy and paradigm for attributing achiement is necessary in the future. </font></p>

<p>The events are collected from Internet sites, published journal articles, and books.</p>
<p><strong>Precision and Accuracy.</strong></p>
<p>The preciseness of the events are completely dependent on the reliability of the data. For example, the domestication of dogs was very controversal and many Westerners claimed that it was clearly occurred in middle East area. However, recent mitchondrial study showed that it is more likely to be in the Far East. The criterion applied in finalising the data is bases on how rigorous the scientific methods were. MtDNA test is more likely to be accurate than some fossil records and conjectures based on the distribution of sub-species of dogs at present times.</p>
<p><strong>Controvesy</strong></p>
<p>Controversal cases such as the contribution of the development of the idea of gravity by Issac Newton and Robert Hooke is a major problem of the history of biology and science. The political and egoistic influence of individuals in the history is estimated to be tremendous. There can be much wrong data purely some scientists were less interested in insisting on the their own contributions with many reasons such as disgust toward more aggressive and self-promoting ones, lack of interest in such external recognition and pure altruism. Scienctists have been strongly political throughout the history contrary to the general perception of their objectiveness, honesty, fairness and alruistic behaviours by the public. This is partly due to the Western culture's strong recognition on individuals' contribution to the development of humanity. This report's philosophy (the highest level decision principle) is to minimize such bias toward more politically active inventors and scientists. In other words, the most factual data in the widest aspects are sought after. For example, even though Gutenberg's contribution of inventing movable types and printing machine has contributed significantly to the European social, religoius, scientific and political development, he is regarded as an enterpreneur rather than the original thinker or inventor. Recording name for the invention for the humanity will be akin to recording William Gates of Microsoft as the inventor of modern computer operating system (OS) because 99% of the public in China may not know that there were other OSs. </p>
