Ученые объяснили появление длинной шеи у жирафов

Изучив позвонки вымерших предков жирафов, американские исследователи пришли к выводу, что длинная шея этих животных возникла в два этапа эволюции. Один из позвонков вытянулся в сторону головы, а спустя несколько миллионов лет уже у другого вида он удлинился по направлению к хвосту.

Так стоп. Любая эволюционная штуковина в биологических видах от хаотичной мутаций, которые в последствии давали преимущества перед другими менее удачливыми видами и позволяли пер дать эти признаки потомкам. Что тут ещё выяснять то?
