The feet of a person with six toes on each foot Whenever protons and electrons bump into each other, or atoms bump into each other, or molecules bump into each other, or prokaryotic cells bump into each other, or DNA molecules inside cells divide - whenever any of these things happen, they can happen [...]

RNA molecule: A single strand of RNA, seen under an electron microscope The RNA molecule was probably one of the earliest steps towards life on Earth. RNA is short for "ribonucleic acid". That's a very long, complicated molecule made out of amino acids linked together. The amino acids are made out of atoms of [...]

Highly magnified view of a cell wall Around four billion years ago, some of the amino acid molecules that were on the planet Earth began to join together into bigger molecules with hundreds of atoms in them, called lipids. This happened in the water in the oceans on Earth, because there wasn't any land [...]

Oil and water You can easily see for yourself how the amino acids, trying to get as far away from the water as possible, formed into little spheres or bubbles. Just take a glass of water and put it on the table. Then slowly pour in some vegetable oil. You'll see that the [...]
