Kirchner claimed that Lovelock and Margulis had not presented one Gaia hypothesis, but four.

In contrast, on Daisyworld competition between the daisies based on temperature-effects on growth rates leads to a shifting hipotwsis of daisy populations that tends to favour a planetary temperature close to the optimum for daisy growth. Lovelock has suggested that global biological feedback mechanisms could evolve by natural selectionstating that organisms that improve their environment for their survival do better than those that damage their environment.

Gaia hypothesis

After initially being largely ignored by most scientists from untilthereafter for a period the initial Gaia hypothesis was criticized by a number of scientists, such as Ford Doolittle[54] Richard Dawkins [55] and Stephen Jay Gould.

Lovelock and other Gaia-supporting scientists, however, did attempt to disprove the claim that the hypothesis is not scientific because it is impossible to test it by controlled experiment. However, she objected to the widespread personification of Gaia and stressed that Gaia is “not an organism”, but “an emergent property of interaction among organisms”.

In some versions of Gaia philosophyall lifeforms are considered part of one single living planetary being called Gaia. Gaia scientists see the participation of living organisms in the carbon cycle as one of the complex processes that hipotesis de gaia conditions suitable for life.

The role of selection is to favor organisms that are best adapted to prevailing environmental conditions. However, the composition of seawater is far from hi;otesis, and it is difficult to explain this fact without the influence of organic processes.
