Chapter 25- Origin of life on earth The earth is estimated to have formed about 4.6 years ago condensing from a cloud of dust and rock. For the first few hundred millions years the Earth was being bombarded by huge chunks of rock and ice. The collisions created enough eat to vaporise the adavible water and prevent seas from forming. The early earth had a reducing atmosphere (electron adding) and there was no oxygen in the atmosphere, and as a result there was no need for an ozone layer to protect the earth from high levels of UV radiation.

Prokaryotes- An organism of the kingdom Monera (or Prokaryotae), comprising the bacteria and cyanobacteria; characterized by the absence of a distinct, membrane-bound nucleus or membrane-bound organelles, and by DNA that is not organized into chromosomes. Spontaneous generation- mistaken idea that life can arise from nonliving materials Biogenesis- Idea that living organisms come only from other living organisms. Protocell- Large, ordered structure, enclosed by a membrane, that carries out some life activities, such as growth and division. Archaebacteria- Chemosynthetic prokaryotes that live in harsh environments, such as deep-sea vents and hot springs The Origin of Life Origins: The Early Ideas Spontaneous generation The idea that nonliving material can produce life
