Ernst Haeckel, German naturalist and artist,
was born February 16, 1834. He was one of the first biologists to
accept the theory of evolution and created phylogenetic trees to show
the relationships of various animals (including humans).
It´s curious to
note that one of Haeckel´s drawings features also in the 1995 anime „Ghost in the Shell“, when the puppet master - a sentient A.I. - discusses evolution as descent with modification:
copy is just an identical image. There is the possibility that a single
virus could destroy an entire set of systems and copies do not give
rise to variety and originality. Life perpetuates itself through
diversity and this includes the ability to sacrifice itself when
necessary. Cells repeat the process of degeneration and regeneration
until one day they die, obliterating an entire set of memory and
information. Only genes remain. Why continually repeat this cycle?
Simply to survive by avoiding the weaknesses of an unchanging system.”

Biogeomorphology, also referred as ecogeomorphology or sometimes as zoogeomorphology,
is the study of the links between ecology and geomorphology, or in
simple terms between life-forms and landforms. Such interactions range
from simple tracks left by an organism in the landscape to the complex
cycles of energy and matter transfer (like for the element carbon)
between the biosphere and the lithosphere.
The role of animals in the evolution of
a landscape is still poorly studied, but one of the most interesting
processes modifying a landscape involves digging animals.Read On...
“What’s in a name?” asked William Shakespeare in his play Romeo and Juliet. It may also be of interest to explore the origin of some common terms used in geology in an upcoming series, like feldspar, the most common mineral on earth´s surface Read On…
In August 1881, the journal Science (a short-lived predecessor of the modern journal) published an article
based on letters exchanged between two amateur geologists – British
Charles R. Darwin and the German Otto Hahn – discussing the possibility
of extraterrestrial life. Just some years earlier, Darwin had published On The Origin of Species, arguing that complex life forms evolved very slowly over time from simple ones.
However, Darwin faced a major problem with his theory. At the time, based on erroneous calculations of the cooling rate of earth by physicist Lord Kelvin, the Earth was believed to be just some million years old.
Accordingly, the planet seemed too young to explain the modern
complexity and diversity of life. However, if already complex
microorganisms existed in space (the existence of which would predate
the formation of Earth), and only later they evolved in terrestrial
animals, could solve this apparent contradiction.
