Is there any credible evidence for the theory of Spiral Dynamics? Spiral dynamics is a developmental psychology based theory that postulates these main ideas:


Organisms in the universe go through a predictable set of stages of psychological development. 
These stages each exhibit a set of values that the organism tries to obtain. 
Their pursuit for these values are clearly observable, i.e. it is possible to identify that the organism is trying to obtain these values. 


This image illustrates the different stages postulated by the theory, the characteristics of organism's behavior that are within each level, and also their overall world view.


Here is a table (Dr. Clare Grave's model) that breaks down these characteristics into categories:



I have heard that this theory is credible and that there is evidence for it, though I have struggled to find any.

Is there any evidence that strongly suggests all living organisms/creatures/life forms, in terms of mentality, consistently travel through a set of stages, where their values (and overall objectives) are respectively: gaining assurance, obtaining survival, obtaining security, obtaining independence, and then obtaining affiliation.

While Dr. Graves himself did studies to produce this theory, his methods have been criticized heavily. At this point of time, are there any other studies that suggest that the postulate mentioned is consistent with various empirical observations?
Dr Graves' research relates to human developmental psychology, not 'all living things'. In his book Integral Psychology (2000) Ken Wilber cross references multiple bodies of work, including eastern philosophy and western psychology. Wilber mentions a number of other researchers whose work correlates with Graves' findings, including Paiget, Fowler, Kegan, Cook-Greuter to name a few. 

Three key findings from Graves' work are:
1. The responsive nature of human consciousness to the complexity of life conditions.
2. The trajectory of and the human experience of change between the stages.
3. The open-ended, staged developmental sequence with alternating themes of self-expression and self-sacrifice.
