Re: Man's best friend shares most genes with humans

Pim

If you have genes in common with dogs you may be dog-like. That is you might
be friendly affectionate loyal etc. Maybe that is what Janice is afraid of!

Our previous dog often looked at us with the same expression as Princess
Diana, so we always said there was a genetic similarity and relationship!

Why get worried if we share behaviour or genes with animals? We do and that
is the end of it. All it does is to prove Darwin right, but I have known
that for years!
