This book retells classic biology. With the exception of one well-marked chapter, nothing you will read in here is in any way original or controversial.

Now, seasoned biologists might feel that some of my phrasing is different from the words that they’d prefer, but that is ok. We have different audiences. I have however strived to not ever confuse the reader with needlessly imprecise or unconventional terms.

Or put another way, after having read this book, you can talk to the professionals, and you’ll sound normal to them. If you decide to delve into the vast existing literature, you will see the same words being used.

Biology is complex, and it is always possible I got it wrong somewhere. If so, please let me know urgently so I can address the problem. A register of errata can be found on XXX.
