After working in the IT industry for 32 years, I took early retirement in 2009 to work full time on my project to write a complete introduction to human evolution and prehistory; from the first apes to the first cities. "Humans: from the beginning" was completed early in 2014 and is now available on Amazon as a Kindle edition (see http://www.humansfromthebeginning.com for more details)..I handled all technical aspects of the eBook publication process myself, drawing on my IT knowledge.I am now working on a shorter and more 'populist' version of my book, which will be made available as a paperback as well as a Kindle edition.
