The History of Biology however, focuses on the advent of life on earth, right from the ancient times. The articles in this issue provide an eclectic look at that history, from ideas about the origin of life, through key developments such as the ‘great oxygenation event’ and mass extinctions, to the evolutionary history of particular phylogenetic groups. Traditionally, the history of biology is diversified into two wings – studies on medicine and theories of natural history. As living things have evolved and diversified, first in the oceans and then on earth, they have dramatically changed the environment they inhabit [, A big thank you to all the authors who have contributed articles to this special issue, and again (see [.

The first living organisms, in the current model of evolution, are thought to be Prokaryotes 1.The oldest known fossilised prokaryotes have been dated to approximately 3.5 billion years ago, only 1 billion years after the formation of the Earth's crust. The series took 3 years to make and took Attenborough all over the world. Lessons. Learn. Yet it is also clear that evolution is not driven by ‘progress’ — with the exception of the artificial selection we have used in the domestication of animals and plants for our own purposes, evolution is a blind watchmaker, and can lead to loss and simplification as well as gain and an increase in complexity.

However for most of the time he stayed out of the picture and provided a discreet commentary, allowing the impressive photography to speak for itself. The oldest meteorite fragments found on Earth are about 4.54 billion years old; this, coupled primarily with the dating of ancient lead deposits, has put the estimated age of Earth at around that time. Many creatures and behaviours were captured on film for the first time; the programme showed the living fossil fish coelacanth, and the spectacular courtship displays of birds of paradise.
