Muri ayo mazi y imishyuhira harimo imyuka nka NH3, CO2, CH4, etc. Iyo myuka yashongeye mu mazi biravanga, CO2 iragabanuka, za Glucides (amasukari) ziriyongera. Ayo masukari yaje kwivanga na Oxygène bibyara Alcool, Aldéhydes, cétones na Acides Organiques. Byaje kuvamo NH3, Acides Aminés, protéines bitinze biza gufatana n imyunyu (sels) havuka igitonyanga cyitwa Coocervate gifite ubushobozi bwo gukurura no kumira utuntu duto turi mu mazi.


Nyuma y imyaka 4 000 000 000 Coocervate yabyaye Protozoaires (organismes unicellulaires) nka algues bleues, Virus, Amibes, Bactéries, etc., n ubu ziriho. Izi protozoaires zaje kubyara Metazoa (organisme pluricellulaire) ziba zikanabyarira mu mazi, izishobora kuba kubutaka ariko zigatera amagi mu mazi, izishobora kuba no kubyarira 
kubutaka etc.

Intambwe yanyuma yabaye urwego rwitwa Mamalia (Mammifères) zifite ubushyuhe (températures) budahinduka, zitwita zikonsa urub
