Nature: зубы и уши развились у млекопитающих в юрском периоде

CULTURE

Международная группа ученых из Китая, США и Австралии выяснила, когда у млекопитающих впервые появились уши и зубы. Эти характерные черты в ходе эволюции унаследовали и люди. Исследование опубликовано в научном журнале Nature.

Палеонтологи изучили четыре окаменелости возрастом более 164 млн лет, относящихся к юрскому периоду. Три из них оказались останками шуотериид: маленьких существ размером с мышь.

Специалисты сопоставили зубы шуотериид с докодонтами — другой группой млекопитающих, которая рано ответвилась от других видов. Ученые пришли к выводу, что шуотерииды находились ближе к докодонтам, чем считалось раньше.

Исследователи также сравнили более древних животных с шуотериидами и обнаружили недостающее звено эволюции, показавшее переход от рептилий с одной костью в среднем ухе к млекопитающим, у которых три кости в среднем ухе.

По словам палеонтологов, загадку развития среднего уха у млекопитающих деятели науки не могли разгадать со времен Чарльза Дарвина.

Ученые добавили, что маленькие существа, сновавшие под ногами динозавров, оказались важной вехой для эволюции современных видов, включая людей.
