Только ли люди заставляют исчезать другие виды?

[notabler]

Совсем нет. Примерно 2 миллиона лет назад людей не было, так что все виды на земле исчезали без его участия.  В широко известных случаях массового исчезновения видов, как в Пермском или Меловом периодах, возможно, случились глобальные катастрофы, такие, как столкновение Земли с астероидом. 
Однако основная тяжесть вины за исчезновение видов теория эволюции возлагает на конкуренцию между видами, заставляющую близкородственные виды исчезать.  Мы происходим от приматов, которые произошли от млекопитающих с четырьмя конечностями, которые произошли от рыб, которые произошли от беспозвоночных. Современные образцы всех этих видов все еще существуют в природе, а наши прямые прародители исчезли, потому что их заставили исчезнуть. 
Однако процесс исчезновения видов не останавливался никогда и протекает сейчас: к примеру, рыжие белки вытесняются серыми, очень быстро.

СПАСИБО! Но отчего-то грустно... :(

А чего грустить то? Эволюция, против нее не попрешь... Нормальный ход вещей

Было бы интересно узнать кто вытеснит нас.
