Gaia: Argument over a single word

THESIS: Life on earth has been considered by some as a purposeful interaction tending toward ecological stability. However, when the scientific community led by James Lovelock tried to match this concept with science, it was (and continues to be) a dilemma.

Introduction

Whenever one hears the word Gaia, he or she will also hear life, goddess, purpose, ecology, and undoubtedly controversy. Not many topics have provoked more controversy among the scientific community than the idea that the atmosphere, biosphere, and its living organisms behave as a single system, striving to maintain a stability that is conducive to the existence of life—the so-called Gaia theory or Gaia hypothesis.

On the other hand, the idea—which, in my opinion, should be seen more naturally—is attracting more and more followers. Scientists have begun to consider the topic since the beginning of the last decade, because the pertinent nature of it requires them to do so. Linden states that at the end of the first conference on Gaia in 1988, James Lovelock, a highly respected biologist and the author of the theory, received a great ovation . But the idea which supposes that all species and living matter on the earth are able to interact and maintain the process of life is not actually original to Lovelock. Although most people believe Lovelock was the first scientist to think up the Gaia hypothesis, it was actually in 1785 when Scottish geologist James Hutton had figured it out already. It was not until the 1970s that the theory started to gain force, when Lovelock collaborated with Lynn Margulis, a renowned microbiologist ( 114).

Lovelock started to think about the hypothesis for the first time in the 1960s, when he was asked by NASA to help to design life-detecting instruments to determine if there is life on Mars. He supposed that, were there life on Mars, the atmospheric composition and balance of gases would be equal to or at least similar to the earth's (Morton 96). Gases, as well as
