In 1997, Tyler Volk argued that a Gaian system is almost inevitably produced as a result of an evolution towards far-from-equilibrium homeostatic states that maximise entropy production, and Kleidon (2004) agreed stating: "...homeostatic behavior can emerge from a state of MEP associated with the planetary albedo"; "...the resulting behavior of a biotic Earth at a state of MEP may well lead to near-homeostatic behavior of the Earth system on long time scales, as stated by the Gaia hypothesis". Staley (2002) has similarly proposed "...an alternative form of Gaia theory based on more traditional Darwinian principles... In [this] new approach, environmental regulation is a consequence of population dynamics, not Darwinian selection. The role of selection is to favor organisms that are best adapted to prevailing environmental conditions. However, the environment is not a static backdrop for evolution, but is heavily influenced by the presence of living organisms. The resulting co-evolving dynamical process eventually leads to the convergence of equilibrium and optimal conditions".

1997年,泰勒·沃尔克认为,盖安系统几乎不可避免地会产生,这是一种向远离平衡的稳态演化的结果,这种平衡状态使熵产生最大化,克莱顿(2004)同意这样的说法:“自稳态行为可以从与行星反照率相关的MEP状态中产生”;“……一个如盖亚假说所述,处于MEP状态的生物地球很可能导致地球系统在长时间尺度上的近稳态行为。Staley(2002)同样提出了“……一种基于更传统的达尔文原理的盖亚理论的替代形式。在这种新方法中,环境调控是人口动态的结果,而不是达尔文的选择。选择的作用是偏爱最能适应当前环境条件的有机体。然而,环境并不是进化的静态背景,而是受到生物存在的严重影响。由此产生的共同进化动态过程最终导致平衡和最优条件的收敛。

In a 2013 book-length evaluation of the Gaia hypothesis considering modern evidence from across the various relevant disciplines, Toby Tyrrell concluded that: "I believe Gaia is a dead end. Its study has, however, generated many new and thought provoking questions. While rejecting Gaia, we can at the same time appreciate Lovelock's originality and breadth of vision, and recognise that his audacious concept has helped to stimulate many new ideas about the Earth, and to champion a holistic approach to studying it". Elsewhere he presents his conclusion "The Gaia hypothesis is not an accurate picture of how our world works". This statement needs to be understood as referring to the "strong" and "moderate" forms of Gaia—that the biota obeys a principle that works to make Earth optimal (strength 5) or favourable for life (strength 4) or that it works as a homeostatic mechanism (strength 3). The latter is the "weakest" form of Gaia that Lovelock has advocated. Tyrrell rejects it. However, he finds that the two weaker forms of Gaia—Coeveolutionary Gaia and Influential Gaia, which assert that there are close links between the evolution of life and the environment and that biology affects the physical and chemical environment—are both credible, but that it is not useful to use the term "Gaia" in this sense and that those two forms were already accepted and explained by the processes of natural selection and adaptation.

2013年,托比·泰瑞尔在对盖亚假说的一本书长度评估中总结道:“我认为盖亚假说是一条死胡同。然而,它的研究产生了许多新的和发人深省的问题。在拒绝盖亚假说的同时,我们也能欣赏到洛夫洛克的独创性和广博的视野,并认识到他大胆的概念有助于激发许多关于地球的新想法,并倡导一种整体的方法来研究地球”。在其他地方,他提出了自己的结论:“盖亚假说并不是我们这个世界如何运转的精确图像”。这种说法需要被理解为是指盖亚假说的“强”和“中”形式,生物群遵循的原则是使地球成为最佳(强度5)或有利于生命(强度4),或是作为一种内稳态机制(强度3)。后者是洛夫洛克所提倡的盖亚假说的“最弱”形式。泰瑞尔拒绝了。然而,他发现盖亚假说的两种较弱的形式:共同进化的盖亚假说和有影响力的盖亚假说,它们断言生命的进化和环境之间有密切的联系,生物学影响物理和化学环境,这两种说法都是可信的,但在这个意义上使用“盖亚假说”一词是没有用的,两种形式已经被自然选择和适应过程所接受和解释。
