ڈائر بھیڑیا
ڈائر بھیڑیا (کینس ڈرس، "ڈراؤنا کتا") جینس کینس دی اک الوپ ہو رہی پرجاتی اے۔ ایہہ اتری امریکہ وچ سبھ توں مشہور پرانے ماساہاری پراجاتیاں وچوں اک اے، اسدے نال ہی الوپ ہوئیاں پراجاتیاں وچ صابر-دنداں والی سمائیلڈن پھیٹلس بلی اے۔ پچھڑے پلائسٹوسین اتے مڈھلے ہولوسین یگ (125,000-9,500 سال پہلاں) دوران ڈائر بھیڑیا امریکہ وچ پایا جاندا سی۔ پہلے کجھ نمونیاں دے ملن توں چار سال بعد اس پراجاتی دا نام 1858 وچ رکھیا گیا سی۔ ایہناں دو اپ-پرجاتیاں نوں مانتا حاصل اے: پہلی کینس ڈرس گلدائی اتے دوجی کینس ڈرس ڈرس آدی۔ ڈائر بھیڑیا شاید اتری امریکہ دے آربربسٹر دے بھیڑیئے (کینس آربربسٹرِ) توں ترقی یافتہ ہویا سی۔ اس دے جیوک دیساں دا سبھ توں وڈا مجموعہ لاس اینجلس دے رانچو لا بریا ٹار پٹس توں حاصل کیتا گیا اے۔
اتری امریکہ دے میداناں، گھاہ دے میداناں اتے جنگل والے کجھ پہاڑی کھیتراں، دکھنی امریکہ دے سکے سناہ وچ بہت سارے کھیتر ایہناں بھیڑیئے دے نواس تھاں وجوں پائے گئے ہن۔ جنہاں دی سمندر پدھر توں اچائی ۲٬۲۵۵ میٹر (۷٬۴۰۰ فٹ) اے۔ ڈائر بھیڑیئے دے جیوک حصے 42 42 دے اتر وچ شاید ہی لبھے گئے۔ اس ادھار تے صرف پنج غیر-تائید رپورٹاں آئیاں ہن۔ ایہہ سیما پرتبندھ لورینٹائیڈ اتے کورڈلرن برف دیاں چادراں جو اس ویلے موجود سی دے نزدیکی تاپمان، شکار جاں رہائشی سیماواں دے کارن منیا جاندا اے۔

[سودھو]1850 ویں دہاکے توں ریاست ہائے متحدہ وچ الوپ ہوئے وڈے بھیڑیئے دے جیوک اخاص پائے جا رہے ہن پر ایہہ ترنت واضع نہیں ہویا سی کہ ایہہ سارے اک جاتی نال متعلق سن۔ بعد وچ کینس ڈرس نال متعلق اسدا پہلا نمونہ 1854 دے ادھ وچ انڈیانا دے اوانسولے نیڑے اوہیؤ ندی کنارے پایا گیا۔ جیوک سائنسدان جوسیپھ گرینولے نوروڈّ نے ایوینسولے دے کلیکٹر پھرانسس اے لنک توں گلھاں دے دنداں نال پھوسلائجڈ جباڑے نوں حاصل کیتا۔ پراتتو سائنسدان جوسیپھ لیڈی نے ایہہ مقررہ کیتا کہ ایہہ نمونہ بھیڑیئے دی اک الوپ ہو رہی پرجاتی نوں درساؤندا اے اتے کینس پرائیمیوس دے نام ہیٹھ اسدی رپورٹ درج کیتی گئی اے۔[۲] پھلاڈیلپھیا دی قدرتی سائنس اکیڈمی وکھے نوروڈّ دے پتراں نوں لیڈی نوں لکھیاں قسماں دے نمونے (اک پرجاتی وچوں پہلی جس دا لکھتی ذکر اے) دے نال سرکھات رکھیا گیا اے۔1857 وچ نیبراسکا وچ نیؤبرا ندی گھاٹی دی کھوج کردیاں لیڈی نوں اک الوپ ہو رہی کینس پراجاتی دا ورٹبرا ملیا جسنے اسنوں ڈائرس نام دتا۔[۳] پرائیمیوس (لیڈی 1854) نوں بعد وچ کینس انڈیئنسس (لیڈی 1869) دا نام دتا گیا جدوں لیڈی نوں پتہ لگیا کہ اسدا نام پریمائیوس سی، جو پچھلی بریٹیش کدرتوادی برائن ہوٹن ولوں ورتیا گیا سی۔[۴]
