Sceptre Of Selection

Sceptre Of Selection

As I noted in an earlier blog (Mitochondrial Evolution & Speciation), as the maternal mtDNA line is thought by scientists to be pivotal in the natural selection and evolution of species, so too are there natural selection processes going on in the blood, organs, tissues and systems of the human body. For example, many of us are aware of the Rh incompatibility that occurs when an Rh- woman becomes pregnant with an Rh+ fetus (a factor the fetus inherits from the father). The mother's body will react to the fetus as a foreign body, and without medical intervention, this maternal biological reaction may cause potentially fatal hemolytic anemia in the fetus (especially in pregnancies following the first pregnancy). 

As a former biological scientist whose research work involved working with cell-cell receptor interactions and receptor mediated cell activation processes, over two decades ago I wrote a poem about the real magic of another natural selection process which unfolds in the human immune and blood systems called Scepter of Selection:

cell to cell, receptor to receptor
a fit communication
an exchanging interaction, immortalized, specific
naturally essential, particularly recognized
the only true selection
universally evident in the matter
with perfect complimentary
positive and negative
working completely together for good
ordering with chaos
a most functional system of defense
in the complex environment
full of simple orchestrations
a developing music into being
playing through generations and times
turning over
the epiphany of history
through her handle on blood biology
