LESSON 1 Origin of Life on Earth Learning Objectives • Describe how Earth was formed. • Describe the events that happened during Earth's formation. When and where did life possibly start? Many cultures develop different versions about the origin of life. However, modern scientists are still exploring the works of some well-known experts in the history of science in search of the true origin of life. Earth is said to be a little over 4.5 billion years (Gigaannum or Ga) old. The oldest material found on Earth that is estimated to be 4.3 billion years old is a zircon crystal. No one witnessed how Earth was formed and what exactly happened during that moment, but there are evidence that show how it all started. Earth's earliest times were geologically violent. There were continuous bombardment from meteorites. As Earth cooled and the surface solidified, the first solid rocks formed. Continents were not yet present; only a huge ocean with scattered small islands. Events such as erosion, sedimentation, and volcanic activities that were assisted by possible meteor impacts, gradually created the oceanic plates, which later evolved into continents. About 3.8 Ga, life on Earth initially began with single-celled organisms called prokaryotes. Over a billion year later, multicellular life evolved. Some studies show that life-forms began to evolve around 570 million years ago (Ma). This evolution started with early arthropods, followed by the fish (530 Ma), and land plants and forests (475 Ma and 385 Ma, respectively). It was only at around 200 Ma that early mammals emerged. Homo sapiens is believed to have evolved about 200000 years ago. Many things were revealed using fossil evidence, yet many questions remain unanswered about the origin of life. Science is continuously searching for answers on what was in the beginning.
