With Darwin’s discovery of natural selection, the origin and adaptations of organisms were brought into the realm of science.
The Origin of Life
A new measurement of chemical evolution suggests that amino acids filled the early universe some nine billion years before life emerged. That has important implications for understanding the origin of life and attempting to re-create it in the lab.
Human Evolution (Part-3)
A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses.
Human Evolution (Part-4)
A new measurement of chemical evolution suggests that amino acids filled the early universe some nine billion years before life emerged. That has important implications for understanding the origin of life and attempting to re-create it in the lab.

History of the World
Today’s magnetic shield is generated in Earth’s outer core. The intense heat in Earth’s dense inner core causes the outer core — composed of liquid iron — to swirl and churn, generating electric currents, and driving a phenomenon called the geodynamo, which powers Earth’s magnetic field.

tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. … “What it looks like is that oxygen was first produced somewhere around 2.7 billion to 2.8 billon years ago.
