Darwin himself would be fascinated by all the knowledge we have now of matters genetic and it is amazing how many of his conjectures remain sound .<Roger Brook - No Dig Gardenerhttps://www.blogger.com/profile/16210160273591839142noreply@blogger.comtag:blogger.com,1999:blog-2571100417242238211.post-18568293243728962682015-01-25T01:14:10.939+00:002015-01-25T01:14:10.939+00:00Darwin says, "Is it improbable [that] variati...Darwin says, "Is it improbable [that] variations useful in some way to each being in the great and complex battle of life should occur in the course of many successive generations?

I read a book the other day about "Commensual" animals (ones that cohabit with humans), which made me realise that the concept of keeping pets is perhaps a bit artificial. Some animal species made a conscious decision to live with humans simply because it was in their interest to do so.
