Evolutionary biology is the subfield of biology that studies the evolutionary processes that produced the diversity of life on Earth starting from a single origin of life. These processes include the descent of species, and the origin of new species.
The discipline emerged through what Julian Huxley called the synthesis of understanding from several previously unrelated fields of biological research, including genetics, ecology, systematics and paleontology.
Current research has widened to cover the genetic architecture of adaptation, molecular evolution, and the different forces that contribute to evolution including not only natural selection but sexual selection, genetic drift and biogeography. The newer field of evolutionary developmental biology ("evo-devo") investigates how organisms develop (from a single cell through an embryo to an adult body) to find out the ancestral relationships between organisms and how the processes of development evolved.
The study of evolution is the unifying concept in evolutionary biology. Evolutionary biology is a conceptual subfield of biology that intersects with other subfields that are delimited by biological organisation level (e.g., cell biology, population biology), taxonomic level (e.g., zoology, ornithology, herpetology) or angle of approach (e.g., field biology, theoretical biology, experimental evolution, palaeontology). Usually, these intersections are combined into specific fields such as evolutionary ecology and evolutionary developmental biology.
Clinton Richard Dawkins FRS FRSL (born 26 March 1941) is an Englishethologist, evolutionary biologist, and writer. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.
Dawkins first came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centred view of evolution and introduced the term meme. In 1982, he introduced into evolutionary biology the influential concept that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment. This concept is presented in his book The Extended Phenotype. In 2006, he founded the Richard Dawkins Foundation for Reason and Science.
Dawkins is a noted atheist, and is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argues against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he describes evolutionary processes as analogous to a blind watchmaker. In his most popular book, his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion. He is an opponent of creationism being taught in schools. He makes regular television and radio appearances, predominantly discussing his books, his atheism and his ideas and opinions as a public intellectual.
An unidentified flying object, or UFO, in its most general definition, is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. Culturally, UFOs are associated with claims of visitation by extraterrestrial life or government-related conspiracy theories, and have become popular subjects in fiction. While UFOs are often later identified, sometimes identification may not be possible owing to the usually low quality of evidence related to UFO sightings (generally anecdotal evidence and eyewitness accounts).
Stories of fantastical celestial apparitions have been told since antiquity, but the term "UFO" (or "UFOB") was officially created in 1953 by the United States Air Force (USAF) to serve as a catch-all for all such reports. In its initial definition, the USAF stated that a "UFOB" was "any airborne object which by performance, aerodynamic characteristics, or unusual features, does not conform to any presently known aircraft or missile type, or which cannot be positively identified as a familiar object." Accordingly, the term was initially restricted to that fraction of cases which remained unidentified after investigation, as the USAF was interested in potential national security reasons and/or "technical aspects" (see Air Force Regulation 200-2).

As Ed explains, he was a pretty normal kid from the suburbs. A high-school teacher took him out on class field trips, and Ed realized that being a scientist could mean going on field trips as a career. After seeing an early TV show about birds-of-paradise, he knew where he wanted to go. Footage by Tim Laman.
Richard Prum, the author of "The Evolution of Beauty," explains how who a female chooses to mate with can change the common traits that men show. Over time, women can change the evolutionary definition of maleness. Following is a transcript of the video. I’m Richard Prum. I’m the William Robinson co-professor of ornithology at Yale University and I’m the author of “the Evolution of Beauty.” So one of the things that’s really mysterious about people is the evolution of our cognitive complexity, our long childhoods, language, material culture – all of these things. And they take large amounts of investment in babies to get them to grow for a really long time. This pattern of investment was only made possible by overcoming male violence in our primate ancestors. Male chimpanzees and gorill...

Richard Prum, Coe Professor at Yale University and author of “The Descent of Man, and Selection in Relation to Sex,” reveals details of Darwin's theory on gender. This particular hypothesis was not well accepted, even years after Darwin's first publication. Today, this gender theory is being analyzed in a different way. Following is a transcript of the video. Today, most evolutionary biologists think that sexual selection by mate choice is really a kind of natural selection. So, when they see the peacock’s tail or a beautiful ornament in nature, they imagine that it evolves because it provides objective information about the quality of the mate that choosers need to know. However, Darwin himself proposed an alternative theory. And it’s one that I’m very interested in trying to bring back...

The 2016 Boyle Lecture: http://www.gresham.ac.uk/lectures-and-events/the-mathematics-of-evolutionary-biology-implications-for-ethics The latter part of the 20th century saw a revulsion against classic forms of "natural theology" which was propelled as much by theological fashion as by secular scientific resistance. This lecture lays out a cautious case for the reconsideration of a new style of "natural theology". It does so in the light of remarkable new discoveries in mathematicalized accounts of evolutionary "cooperation" which significantly challenge the idea of pervasive randomness in evolutionary processes. The ethical and teleological questions which are raised by these cooperative phenomena, it is argued, demand some sort of meaning-making response and ultimately metaphysical issue...

The narrative is structured as a pilgrimage, with all modern animals following their own path through history to the origin of life. Humans meet their evolutionary cousins at rendezvous points along the way, the points at which the lineage diverged. About the book: https://www.amazon.com/gp/product/061861916X/ref=as_li_tl?ie=UTF8&camp;=1789&creative;=9325&creativeASIN;=061861916X&linkCode;=as2&tag;=tra0c7-20&linkId;=9e0a8c0550522c6788413df1109e6de1 At each point Dawkins attempts to infer, from molecular and fossil evidence, the probable form of the most recent common ancestor and describes the modern animals that join humanity's growing travelling party. This structure is inspired by Geoffrey Chaucer's The Canterbury Tales. The pilgrimage visits a total of 40 "rendezvous points" from rendezvous...
