Brain, body, DNA, "uniqueness"...
It was once thought that each cell in a person's body possesses the same DNA code and that the particular way the genome is read imparts cell function and defines the individual. For many cell types in our bodies, however, that is an oversimplification. Studies of neuronal genomes published in the past decade have turned…

The RNA World hypothesis...
The RNA World hypothesis is a difficult one to accept. It seems to improbable that RNA evolved alone into that elaborate mechanism of self-copying. We prefer believing that other enzymes catalysts evolved separately. (1) Sure. It is like we do not like the idea of a DVD Recorded evolving alone. And we break it up…

Painstaking new analysis of the genetic sequence of the X chromosome -- long perceived as the "female" counterpart to the male-associated Y chromosome -- reveals that large portions of the X have evolved to play…

Biology orthodoxy, bacteria, genes...
Some scientists claim that lab conditions affect the expression of genes in bacteria, actually rendering all biology research based on them... wrong! But OK. Other scientists found that there was little evidence of adaptive genetic response. [1] Phew! Thank God genes expression is affected by the environment only in humans. And animals. And... Wait a…

Minimum requirements for life...
Until now scientists have a hard time defining the minimum set of genes required for life to be created... Various attempts have resulted in various sets of genes which do overlap, but are not identical.. [1] Logical. How can you define the undefined? How can you see the unseen? How can you see the stars if…
