I searched this out one day on the internet and the latest thing I found was the Japanese being worried that the decomposition/degradation of the aged DNA samples had them turning more towards finding a frozen MALE Woolly Mammoth in good enough shape that frozen sperm can be extracted from him to impregnate a female elephant..........

If this be the case then a simple one caliber increase should suffice to allow a little "extra" for the hairy halfbreed.........
