Armand Marie Leroi (born 16 July 1964) [2] is a New Zealand-born Dutch author, broadcaster, and professor of evolutionary developmental biology at Imperial College in London. [3] [4] [5] He received the Guardian First Book Award in 2004 for his book Mutants: On Genetic Variety and the Human Body. He has presented scientific documentaries on Channel 4 such as Alien Worlds (2005) and What Makes Us Human (2006), and BBC Four such as What Darwin Didn't Know (2009), Aristotle's Lagoon (2010), and Secret Science of Pop (2012).
A Dutch citizen, Leroi was born in Wellington, New Zealand. His youth was spent in New Zealand, South Africa and Canada. He was awarded a Bachelor of Science degree by Dalhousie University, Halifax, Canada in 1989, and a Ph.D. by the University of California, Irvine in 1993. [1] This was followed by postdoctoral work at the Albert Einstein College of Medicine, New York City using the nematode Caenorhabditis elegans as an experimental organism. [6] [7]
In 2001, Leroi was appointed lecturer at Imperial College, London. He has written several books, including Mutants: On Genetic Variety and the Human Body. [8] [9] In 2004 he adapted his book into a television documentary series for Britain's Channel 4 entitled Human Mutants. [10]
Leroi has presented two other TV documentary series for Channel 4: Alien Worlds in 2005, and What Makes Us Human in 2006. Despite his TV appearances, Leroi has expressed scepticism about the truthfulness of television creatives. In an email exchange with TV director Martin Durkin, concerning the latter's documentary The Great Global Warming Swindle , Leroi wrote: "left to their own devices, TV producers simply cannot be trusted to tell the truth". [11]
He is also known as one of the first testers of the beneficial acclimation hypothesis. In 2005, Leroi published an article in The New York Times entitled "A Family Tree in Every Gene", which argued for the usefulness of racial types in medical genetics. [12]
In January 2009 Leroi presented the BBC4 documentary What Darwin Didn't Know , which charts the progress in the field of Evolutionary Theory since the original publication of On the Origin of Species in 1859. [13]
In January 2010 Leroi presented the BBC4 documentary Aristotle's Lagoon, filmed on the Greek island of Lesbos and suggesting that Aristotle was the world's first biologist. [2] The documentary account was expanded in his 2014 book The Lagoon: How Aristotle Invented Science. [14] [15] He accepted Aristotle as his "scientific hero", describing: "His genius was simply to invent biology." [6]
Leroi collaborated on the DarwinTunes evolutionary music project, using natural selection to create music. [16] The research findings explained how music choice evolved in the pattern of Charles Darwin's natural selection. [17] The study was published in the Proceedings of the National Academy of Sciences in 2012. [18] Leroi's research team also analysed the musical properties of the US Billboard Hot 100 between 1960 and 2010, and found that popular music emerged in three stylistic revolutions around 1964, 1983 and 1991. The study was published in the Royal Society Open Science in 2015. [19] Explaining the contributions of The Beatles to the evolution of music, he said, "They're not making that [1964] revolution, they're joining it. [20] In 2016, he presented The Secret Science of Pop on BBC4. [21]
Leroi received the EMBO Award for Communication in the Life Sciences of the European Molecular Biology Laboratory in 2006. [22] In 2004, he won the Guardian First Book Award for Mutants: On Genetic Variety and the Human Body. [23] [24] He was awarded the 2014 JBS Haldane Lecture of The Genetics Society. [25] The same year he received the London Hellenic Prize of the Hellenic Centre for The Lagoon: How Aristotle Invented Science. [26]
Aristotle was an Ancient Greek philosopher and polymath. His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.
Evolution is the change in the heritable characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation.
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which is intentional, whereas natural selection is not.
In biology, taxonomy is the scientific study of naming, defining (circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum, class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms.
Zoology is the scientific study of animals. Its studies include the structure, embryology, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek ζῷον, zōion ('animal'), and λόγος, logos.
Evolutionary developmental biology is a field of biological research that compares the developmental processes of different organisms to infer how developmental processes evolved.
The great chain of being is a hierarchical structure of all matter and life, thought by medieval Christianity to have been decreed by God. The chain begins with God and descends through angels, humans, animals and plants to minerals.
Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also called the inheritance of acquired characteristics or more recently soft inheritance. The idea is named after the French zoologist Jean-Baptiste Lamarck (1744–1829), who incorporated the classical era theory of soft inheritance into his theory of evolution as a supplement to his concept of orthogenesis, a drive towards complexity.
The history of zoology before Charles Darwin's 1859 theory of evolution traces the organized study of the animal kingdom from ancient to modern times. Although the concept of zoology as a single coherent field arose much later, systematic study of zoology is seen in the works of Aristotle and Galen in the ancient Greco-Roman world. This work was developed in the Middle Ages by Islamic medicine and scholarship, and in turn their work was extended by European scholars such as Albertus Magnus.
In biology, adaptation has three related meanings. Firstly, it is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process. Thirdly, it is a phenotypic trait or adaptive trait, with a functional role in each individual organism, that is maintained and has evolved through natural selection.
History of Animals is one of the major texts on biology by the ancient Greek philosopher Aristotle, who had studied at Plato's Academy in Athens. It was written in the fourth century BC; Aristotle died in 322 BC.
The four causes or four explanations are, in Aristotelian thought, four fundamental types of answer to the question "why?" in analysis of change or movement in nature: the material, the formal, the efficient, and the final. Aristotle wrote that "we do not have knowledge of a thing until we have grasped its why, that is to say, its cause." While there are cases in which classifying a "cause" is difficult, or in which "causes" might merge, Aristotle held that his four "causes" provided an analytical scheme of general applicability.
Biological or process structuralism is a school of biological thought that objects to an exclusively Darwinian or adaptationist explanation of natural selection such as is described in the 20th century's modern synthesis. It proposes instead that evolution is guided differently, by physical forces which shape the development of an animal's body, and sometimes implies that these forces supersede selection altogether.
What Darwin Didn't Know is a documentary show on BBC Four presented by Armand Marie Leroi which charts the progress in the field of evolutionary theory since the original publication of Charles Darwin's On the Origin of Species in 1859.
A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour, or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet. For example, Boa constrictor is one of the species of the genus Boa, with constrictor being the species' epithet.
DarwinTunes was a research project into the use of natural selection to create music led by Bob MacCallum and Armand Leroi, scientists at Imperial College London. The project asks volunteers on the Internet to listen to automatically generated sound loops and rate them based on aesthetic preference. After the volunteers rate the loops on a five-point scale, software permits the highest rated loops to 'reproduce sexually' and populate the next generation of musical loops.
Aristotle's biology is the theory of biology, grounded in systematic observation and collection of data, mainly zoological, embodied in Aristotle's books on the science. Many of his observations were made during his stay on the island of Lesbos, including especially his descriptions of the marine biology of the Pyrrha lagoon, now the Gulf of Kalloni. His theory is based on his concept of form, which derives from but is markedly unlike Plato's theory of Forms.
Teleology in biology is the use of the language of goal-directedness in accounts of evolutionary adaptation, which some biologists and philosophers of science find problematic. The term teleonomy has also been proposed. Before Darwin, organisms were seen as existing because God had designed and created them; their features such as eyes were taken by natural theology to have been made to enable them to carry out their functions, such as seeing. Evolutionary biologists often use similar teleological formulations that invoke purpose, but these imply natural selection rather than actual goals, whether conscious or not. Some biologists and religious thinkers held that evolution itself was somehow goal-directed (orthogenesis), and in vitalist versions, driven by a purposeful life force. With evolution working by natural selection acting on inherited variation, the use of teleology in biology has attracted criticism, and attempts have been made to teach students to avoid teleological language.

Alternatives to Darwinian evolution have been proposed by scholars investigating biology to explain signs of evolution and the relatedness of different groups of living things. The alternatives in question do not deny that evolutionary changes over time are the origin of the diversity of life, nor that the organisms alive today share a common ancestor from the distant past ; rather, they propose alternative mechanisms of evolutionary change over time, arguing against mutations acted on by natural selection as the most important driver of evolutionary change.
