The central dogma of molecular biology was first enunciated by Francis
Crick in 1958 and re-stated in a Nature paper published in 1970.The
central dogma of molecular biology deals with the detailed residue-by-
residue transfer of sequential information. It states that such

A First-Principles Model of Early Evolution
In a study publishing in PLoS Computational Biology, Shakhnovich et al
present a new model of early biological evolution - the first that directly
relates the fitness of a population of evolving model organisms to the

Roughly in the center of our skull, there is a small sphenoid bone
pocket called "Sella Turcica" (Turkish Saddle, due to its similarity
in shape to same), providing a snug and safe resting place for the
pituitary gland (hypophysis cerebri).

I decided to post all my rebuttals in a single email to avoid
spamming.

It's insufficient to say "that's how it's always been" as far as

I know of two "Tree of Life" websites.  For purposes of comparison,
here is how they both show the relationships among the metazoa:

I dont think evolution cares much about hermits or trying to equip
people to handle isolation. Evolution punishes solitary behaviour with
depression and profound feelings of loneliness.
I think that those that survive bouts of isolation would most likely

Has human evolution stopped? The process of selection and number of
offspring is no more working.
Unfit (e.g. shortsighted,...) individuals pair up with other unfit
individuals and in fact quite often they have more children (e.g. less

Why should they have interacted any differently than they do today?
Ie. no spontaneous polymerization of amino acids.  And no self-replication
of peptides.  Only polymerization driven by expenditure of phosphate

If life has occurred only on the planet earth, that would it make it sui
generis in another important sense.  It would be the only known major
physical process in the entire universe to have occurred only once and
only in one place.

the coming era of horizontal gene transfer by Carl Woese:

Most life exists within a temp zone of 0-50C. Some hardy
souls, thermophiles, can live at higher temperatures.
Life is chemical reactions that best fit 0-50C.
Life is chemical adaptation to a 0-50C. temp zone.

Are insects the only flying non-chordates?
(That thing spiders do with the silk streamers doesn't count.)

My point was, we all know that microbes treated half heartdly will
become more virulant very fast they tend spread so if one think that
geting  partial balance with immunity & virusis is not long lasting
there is very big chance that more of rabbit will come with virulant
