Genes on the loose, but with a purpose
on 17 June 2008
Genetics science has mushroomed the last 50 years, overturning many cherished preconceptions in biology and other Natural Sciences, while buttressing other theories with an abundance of hard scientific evidence. Charles Darwin's Theory of Evolution through Natural Selection has been in the later category, with its core assumptions confirmed by the new data about DNA structure, history and function.
The book is composed by a series of essays on the nature and function of genes within the DNA code, embedded in the cells of every living organism. The author offers ample evidence, from experimental data, about how exactly the workings of genes are ultimately responsible for the shaping and evolution of the Natural World around us. The point of the whole demonstration is to establish that Natural Selection mechanisms, as defined by Darwin about 150 years ago, are alive, well and firmly supported by the new data.
The text is aimed at the general public but some knowledge in basic biology and DNA function will help the reader to follow the arguments more closely. It is not a prerequisite though, since the author explains thoroughly the more stringent points, with help from the illustrations.
The last part of the book is the most disappointing, since it involves the denial of evolution, based on religious grounds, and a dire comment on the continuing destruction we inflict to the planet's ecosystems. The author's position, and one that I personally agree totally with, is that alarm bells are already sounding in many quarters and we no longer have the option of intellectual blindness.
