Al considerar cómo se manifestaría la vida, se dio cuenta de que la atmósfera de la Tierra estaba a órdenes de magnitud del equilibrio químico y que ese desequilibrio no podía deberse puramente a procesos abiológicos, sino que era mantenido en un estado dinámicamente estable por efecto de la vida en el planeta. En aquella época, el análisis espectrométrico de la atmósfera de Marte indicaba que estaba cerca del equilibrio químico y Lovelock concluyó que era poco probable que Marte albergara vida. Dado que la Tierra había tenido organismos biológicos durante al menos 3,2 mil millones de años, Lovelock llegó a la conclusión de que la vida era responsable de la homeostasis planetaria en el sentido de mantener las condiciones óptimas de la superficie, de ahí su Hipótesis Gaia.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In the 1960s, James Lovelock, the inventor of the Electron Capture Detector, was asked by NASA to develop instrumentation to detect life on Mars. In considering how life would manifest itself, he realized that the Earth's atmosphere was orders of magnitude away from chemical equilibrium and that such disequilibrium could not be due purely to abiological processes but was maintained in a dynamically stable state by Life. At that time, spectrometric analysis of the atmosphere of Mars indicated that it was close to chemical equilibrium and Lovelock concluded that Mars was unlikely to harbour life. Since the Earth had had biological organisms within for at least 3.2 thousand million years, Lovelock concluded that life was responsible for planetary homeostasis in the sense of maintaining optimum surface conditions, hence his Gaia Hypothesis.]]></p></abstract>
