spontaneous generation

• نظرية بيولوجية قديمة بطلانها الآن، تقول إن الكائنات الحية يمكن أن تنشأ تلقائياً من مادة غير حية، مثل نشوء اليرقات من اللحم المتعفن. استُخدمت تاريخياً لتفسير أصل أشكال الحياة البسيطة، حتى دحضها لويس باستور وغيره في القرن التاسع عشر.

A now-discredited biological theory that living organisms can arise spontaneously from non-living matter, such as maggots appearing from decaying meat. This concept was historically used to explain the origin of simple life forms before being disproven by Louis Pasteur and others in the 19th century.
