13.2 - Convergent Development

The biological convergence theory [11] is based on the assumption that many similar functionalities have arisen in evolution, independently of one another, through the functional constraints prevailing on the earth. Examples are the wings or the eye, both of which have been independently developed by several species.

Simon Conway Morris [12] is a British palaeontologist. He is the principal representative of the theory of convergence in evolution and the opinion that life is stable because nature has provided the framework for it, and life inevitably follows the selective-adaptive rules. Therefore evolution must necessarily arrive at an intelligent species. The development to complexity and intelligence is almost a program part within evolution.

DNA   The premise of biochemistry and biophysics, based on the periodic system of the elements and also the "codon triplet guide" for building functional units on protein structures, can be formulated as follows:

13.2.1 Axiom
DNA is a universal blueprint for the development of a species.

The development to complexity and intelligence would have to take place on every planet on which this is possible. Furthermore, it may be assumed that there is a certain similarity even in the case of different developmental strands. All species will thus have the following body parts:

humanoid 1) left-right symmetry
2) Fuselage for respiratory and digestive organs
3) upper extremities for handling objects
4) lower extremities for movement
5) Head with sensor organs

Thus it is to be assumed that most intelligent species have developed a humanoid-like shape.
