Die Evolution der Haut und des hautassoziierten Immunsystems
The evolution of the skin and the skin-associated immune system
This paper considers the formation of the skin and its associated structures from the most primitive metazoa to the human being:
- In Porifera the delirnitation from the outer world is incomplete. A proper epidermal sheath does not exist, merely a thin coating in… read more
Goethe und die Evolution
Goethe and evolution
During the 17th and 18th centuries ‘evolution’ literally meant unwrapping what was already there. Goethe and Darwin therefore avoided this term, preferring to use ‘metamorphosis’ or ‘desccnt’. It was Herbert Spencer who first used the term in its modern sense. There upon, however, Goethe was a complete evolutionist… read more

Zeitmuster in der Evolution der Säugetiere und ihrer Vorläufer
Temporal pattern in the evolution of mammals and their ancestors
The fundamental threefold shape of the vertebrates, namely head, trunk and limbs, had formed by the Upper Carboniferous period, primarily in water. After this, in the Permian and Mesozoic periods, the development of the threefolding of organs and parts of the body came… read more

Evolutionary Biology today
Following the initial discovery of photosynthesis and respiration of organic substance, General Biology has discovered the principle of symbiosis at all levels of the living world: in the biosphere as a whole, in the eco-organism of the landscape and in the so-called single organisms of plants and animals,… read more

Zur Autonomieentstehung in der Evolution - Eine Übersicht
The generation of autonomy in evolution - a survey
The hypothesis is advanced that major evolutionary innovations are characterized by an increase of organismal autonomy in the sense of an emancipation from the environment. After a brief overview of some new aspects of the question of macroevolutionary innovations from recent scientific… read more
