Animal Aging Differences
Country: United States
Date: March 2005
Since dogs are mammals with virtually all the same organs
as humans, why do they age so quickly in comparison?
Excellent question, and the answer is not known. We do not know what
controls the aging process in different mammals that would allow one to live
to a maximum of around 100 years while another to live to a maximum of
around 20. We have a lot of clues but no real logical sequence of controls
that regulate aging. For certain, if we figure it out, it will be a very
complex interaction of many genes, RNA's enzymes etc.
