For my own reasons I love Bearded Collies. These are some of my present influences regarding gene pools and breeds etc. With some additions on evolution and co-evolution of humans and canids.
Asthma on Tristan da Cunha
Two articles on how genes for asthma at the start of an island’s colonisation have affected the community today.
Cancer in Tasmanian Devils
Just as an introduction for those unaware of the situation, one prominent theory is that this is an example of natural inbreeding due to an isolated island population. As all the Tasmanian Devils share a similar genetic ‘background’ when they bite one another transferred cancer cells cannot be detected as ‘foreign’ because of the similarity of origin. The animals natural immunity does not kick in. The cancer spreads contagiously due to the lack of identification as a foreign body to the individual.
Please search for Falabella horses there is a good Wikipedia article but the link is broken.
Co-evolution of Humans and Canids
Though not directly related to gene pools, this area interests me in relation to human and dog evolution, especially to Bearded Collies which display many of the traits outlined around 130,000 years ago that would have been part of the cultural and some believe biological development of Homo Sapiens, that’s us.
If the above paper is too deep and scientific then this is a more easy read introduction.
