Titolo: Meglio Darwin!

Timothy Garton Ash ha scritto tra l'altro:
- Il problema fondamentale non è limitato all'Islam. ma concerne la
religione in sè e per sè,  che è superstizione, falsa coscienza,
l'annullamento della ragione.
Il linea di principio il criustianesimo o il giudaismo sono un po'
meglio, in particolare nelle versione abbracciate dalla destra
americana.
Il mondo sarebbe molto migliore se tutti comprendessero le verità
rivelate dalla scienza, confidassero nella ragione umana, e
abbracciassero l'umanesimo laico.
Se prorpio dobbiamo mettere in cornice l'immagine di un vecchio con la
barba, che sia la foto di Charles Darwin.

bello eh? Ma utopico per un bel po'. Abbiama il papa Cazzingher che

KURTZWEIL WROTE:
The Exponentially Quickening Pace of Evolution 
As you will recall, after billions of years, the unremarkable planet
called Earth was formed. Churned by the energy of the sun, the
elements formed more and more complex molecules. From physics,
chemistry was born. 
Two billion years later, life began. That is to say, patterns of
matter and energy that could perpetuate themselves and survive
perpetuated themselves and survived. That this apparent tautology went
unnoticed until a couple of centuries ago is itself remarkable. 
Over time, the patterns became more complicated than mere chains of
molecules. Structures of molecules performing distinct functions
organized themselves into little societies of molecules. From
chemistry, biology was born. 
Thus, about 3.4 billion years ago, the first earthly organisms
emerged: anaerobic (not requiring oxygen) prokaryotes (single-celled
creatures) with a rudimentary method for perpetuating their own
designs. Early innovations that followed included a simple genetic
system, the ability to swim, and photosynthesis, which set the stage
for more advanced, oxygen-consuming organisms. The most important
development for the next couple of billion years was the DNA-based
genetics that would henceforth guide and record evolutionary
development. 
A key requirement for an evolutionary process is a "written" record of
achievement, for otherwise the process would be doomed to repeat
finding solutions to problems already solved. For the earliest
organisms, the record was written (embodied) in their bodies, coded
directly into the chemistry of their primitive cellular structures.
With the invention of DNA-based genetics, evolution had designed a
digital computer to record its handiwork. This design permitted more
complex experiments. The aggregations of molecules called cells
organized themselves into societies of cells with the appearance of
the first multicellular plants and animals about 700 million years
ago. For the next 130 million years, the basic body plans of modern
animals were designed, including a spinal cord-based skeleton that
provided early fish with an efficient swimming style. 
So while evolution took billions of years to design the first
primitive cells, salient events then began occurring in hundreds of
millions of years, a distinct quickening of the pace.8 When some
calamity finished off the dinosaurs 65 million years ago, mammals
inherited the Earth (although the insects might disagree).9 With the
emergence of the primates, progress was then measured in mere tens of
millions of years.10 Humanoids emerged 15 million years ago,
distinguished by walking on their hind legs, and now we're down to
millions of years.11 
With larger brains, particularly in the area of the highly convoluted
cortex responsible for rational thought, our own species, Homo
sapiens, emerged perhaps 500,000 years ago. Homo sapiens are not very
different from other advanced primates in terms of their genetic
heritage. Their DNA is 98.6 percent the same as the lowland gorilla,
and 97.8 percent the same as the orangutan.12 The story of evolution
since that time now focuses in on a human-sponsored variant of
evolution: technology.
