Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments.

Biologists are able to study life at multiple levels of organization. From the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations. Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, perform experiments, and form conclusions about the world around them.

Life on Earth, which emerged more than 3.7 billion years ago, is immensely diverse. Biologists have sought to study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. These various organisms contribute to the biodiversity of an ecosystem, where they play specialized roles in the cycling of nutrients and energy through their biophysical environment.

Boris Karloff in James Whale's 1931 film Frankenstein, based on Mary Shelley's 1818 novel. The monster is created by an unorthodox biology experiment.

Biology appears in fiction, especially but not only in science fiction, both in the shape of real aspects of the science, used as themes or plot devices, and in the form of fictional elements, whether fictional extensions or applications of biological theory, or through the invention of fictional organisms. Major aspects of biology found in fiction include evolution, disease, genetics, physiology, parasitism and symbiosis (mutualism), ethology, and ecology.

Speculative evolution enables authors with sufficient skill to create what the critic Helen N. Parker calls biological parables, illuminating the human condition from an alien viewpoint. Fictional alien animals and plants, especially humanoids, have frequently been created simply to provide entertaining monsters. Zoologists such as Sam Levin have argued that, driven by natural selection on other planets, aliens might indeed tend to resemble humans to some extent. ( Full article...)

Certhidea olivacea.jpg

The Warbler Finch (Certhidea olivacea) is the only member of the genus Certhidea and one of Darwin's finches, the group of 14 or 15 passerine birds first collected by Charles Darwin on the Galápagos Islands during the second voyage of the Beagle. Though sometimes classified in the family Emberizidae, more recent studies have shown it to belong in the tanager family, Thraupidae. Darwin had mistakenly thought it was a wren, but, on return to England, was informed in March 1837 by the ornithologist John Gould that the bird belonged to the group of finches.

Goodall in Tanzania in 2018

Dame Jane Morris Goodall DBE ( /ˈɡʊdɔːl/; born Valerie Jane Morris-Goodall on 3 April 1934), formerly Baroness Jane van Lawick-Goodall, is an English primatologist and anthropologist. Considered to be the world's foremost expert on chimpanzees, Goodall is best known for her 60-year study of social and family interactions of wild chimpanzees since she first went to Gombe Stream National Park in Tanzania in 1960, where she witnessed human-like behaviours amongst chimpanzees, including armed conflict.

She is the founder of the Jane Goodall Institute and the Roots & Shoots programme, and she has worked extensively on conservation and animal welfare issues. She has served on the board of the Nonhuman Rights Project since its founding in 1996. In April 2002, she was named a UN Messenger of Peace. Goodall is an honorary member of the World Future Council.
