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.
