Описание книги

A cutting-edge examination of what it means to be human and to have a 'self' in the face of new scientific developments in genetic editing, cloning and neural downloading.After seeing his own cells used to grow clumps of new neurons – essentially mini-brains – Philip Ball begins to examine the concepts of identity and consciousness. Delving into humanity's deep evolutionary past to look at how complex creatures like us emerged from single-celled life, he offers a new perspective on how humans think about ourselves.In an age when we are increasingly encouraged to regard the 'self' as an abstract sequence of genetic information, or as a pattern of neural activity that might be 'downloaded' to a computer, he return us to the body – to flesh and blood – and anchors a conception of personhood in this unique and ephemeral mortal coil. How to Build a Human brings us back to ourselves – but in doing so, it challenges old preconceptions and values. It asks us to rethink how we exist in the world.

No one knew what this stuff did until the mid-1940s, when the Canadian-American physician Oswald Avery and his co-workers at the Rockefeller University Hospital in New York reported rather conclusive evidence that genes in fact reside on DNA. That idea was not universally accepted, however, until James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin and their co-workers revealed the molecular structure of DNA – how its atoms are arranged along the chain-like molecule. This structure, first reported in 1953 by Watson and Crick, who relied partly on Franklin’s studies of DNA crystals, showed how genetic information could be encoded in the DNA molecule. It is a deeply elegant structure, composed of two chain-strands entwined in a double helix.

The double helix of DNA. This iconic image creates a somewhat misleading picture, since for most of the time DNA in a cell’s chromosomes is packaged up quite densely in chromatin, in which it is wrapped around proteins called histones like thread on a bobbin. The “rungs” of the double-helical ladder consist of pairs of so-called nucleotide bases (denoted A, T, C and G) with shapes that complement each other and fit together well.
