For a thousand years the wild sika deer of Nara Park have been considered sacred in Japanese cultivation . Their status has protected them from hunting and isolate from other population of wild sikas , which harmonise to unexampled research has preserved a rarefied patrimonial population that ’s genetically unique from other wild deer .
Nara Park ’s Japanese deer cervid are a uncommon example of human activity preserving wildlife populations , as typically what we get up to tend to harm animal rather than help them . The forests that surround religious shrines in Japan are typically no - hunting - zones , stand for they become a site of prophylactic for crazy species likeCervus nippon , theJapanese sika deer .
view a holy tool in Japan ’s history , sika deer have featured in many myths and stories of old . Their import in human cultivation has efficaciously establish protected arena for the fauna since ancient time , which scram researchers wondering what essence this phantasmal sanctuary might have had on their desoxyribonucleic acid .

" Legend has it that the sika deer in Nara Park had long been strictly protect as courier of the gods , ” said co - author Dr Toshihito Takagi in astatement from Fukushima University . “ Today , these deer are one of the most pop tourist attractions in Japan . However , there has been small genic research on the stemma of these deer . "
Armed with 294 muscle and profligate samples , Takagi and co-worker bear a transmitted depth psychology and were able to identify three distinct genetic group among cervid sampled from 30 sites across the Kii Peninsula . These admit an Eastern genetic chemical group , a westerly genetic chemical group , and an isolated genetic group made up of deer living around the religious asylum of Kasuga Taisha Shrine .
It indicate that there ’s a qualified flow of genes across the maternal descent in this group , which could tie into the fact that females run to stick to a home ground once they get hold one they care . This choosiness restrain their chance of breed with group that are genetically very unlike , leading to these set-apart groups exhibiting unique genetic lineages .
Their genotype data point that the religious sanctuary ’s group diverged after than the others , coinciding with the establishment of the Kasuga Taisha Shrine . It ’s potential , then , that their unique genetical edition has been keep thanks to the inadvertent protect domain in a way that furious populations further abroad were n’t .
" broadly speaking , Japanese sika deer population have been negatively impacted by home ground atomization and regional extinction owing to human activity , ” explained Takagi . “ Our research prove that the religious aegis helped rare transmissible populations of Japanese deer deer survive in Nara Park for more than 1,000 years , while the surrounding populations disappeared due to historical search and small town . "
The findings are pivotal for the preservation of these animals , whose increase universe has made them a problem for farming and forestry . They ’re also increasingly encounter population that historically they ’ve not come in into tangency with , which could see their unique derivation get lost in the intermixture .
