Richard Charles Lewontin was an American evolutionary biologist, mathematician, geneticist, and social commentator. A leader in developing the mathematical basis of population genetics and evolutionary theory, he applied techniques from molecular biology, such as gel electrophoresis, to questions of genetic variation and evolution.
Evolutionary biology is the subfield of biology that studies the evolutionary processes that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. In a population, the genetic variations affect the phenotypes of an organism. These changes in the phenotypes will be an advantage to some organisms, which will then be passed on to their offspring. Some examples of evolution in species over many generations are the peppered moth and flightless birds. In the 1930s, the discipline of evolutionary biology emerged through what Julian Huxley called the modern synthesis of understanding, from previously unrelated fields of biological research, such as genetics and ecology, systematics, and paleontology.
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.
The grandmother hypothesis is a hypothesis to explain the existence of menopause in human life history by identifying the adaptive value of extended kin networking. It builds on the previously postulated "mother hypothesis" which states that as mothers age, the costs of reproducing become greater, and energy devoted to those activities would be better spent helping her offspring in their reproductive efforts. It suggests that by redirecting their energy onto those of their offspring, grandmothers can better ensure the survival of their genes through younger generations. By providing sustenance and support to their kin, grandmothers not only ensure that their genetic interests are met, but they also enhance their social networks which could translate into better immediate resource acquisition. This effect could extend past kin into larger community networks and benefit wider group fitness.
Deborah Charlesworth is a population geneticist from the UK, notable for her important discoveries in population genetics and evolutionary biology. Her most notable research is in understanding the evolution of recombination, sex chromosomes and mating system for plants.
Richard Eimer Lenski is an American evolutionary biologist, a Hannah Distinguished Professor of Microbial Ecology, Genetics and Evolution, and Evolution of Pathogen Virulence at Michigan State University. He is a member of the National Academy of Sciences and a MacArthur Fellow. Lenski is best known for his still ongoing 35-year-old long-term E. coli evolution experiment, which has been instrumental in understanding the core processes of evolution, including mutation rates, clonal interference, antibiotic resistance, the evolution of novel traits, and speciation. He is also well known for his pioneering work in studying evolution digitally using self-replicating organisms called Avida.
Joan Roughgarden is an American ecologist and evolutionary biologist. She has engaged in theory and observation of coevolution and competition in Anolis lizards of the Caribbean, and recruitment limitation in the rocky intertidal zones of California and Oregon. She has more recently become known for her rejection of sexual selection, her theistic evolutionism, and her work on holobiont evolution.
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes (diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes.
Mary Jane West-Eberhard is an American theoretical biologist noted for arguing that phenotypic and developmental plasticity played a key role in shaping animal evolution and speciation. She is also an entomologist notable for her work on the behavior and evolution of social wasps.
Sarah Perin "Sally" Otto is a theoretical biologist, Canada Research Chair in Theoretical and Experimental Evolution, and is currently a Killam Professor at the University of British Columbia. From 2008-2016, she was the director of the Biodiversity Research Centre at the University of British Columbia. Otto was named a 2011 MacArthur Fellow. In 2015 the American Society of Naturalists gave her the Sewall Wright Award for fundamental contributions to the unification of biology. In 2021, she was awarded the Darwin–Wallace Medal for contributing major advances to the mathematical theory of evolution.
Cynthia Beall is an American physical anthropologist at the Case Western Reserve University, Cleveland, Ohio. Four decades of her research on people living in extremely high mountains became the frontier in understanding human evolution and high-altitude adaptation. Her groundbreaking works among the Andean, Tibetan and East African highlanders are the basis of our knowledge on adaptation to hypoxic condition and how it influences the evolutionary selection in modern humans. She is currently the Distinguished University Professor, and member of the U.S. National Academy of Sciences and the American Philosophical Society.
Johanna Schmitt is an evolutionary ecologist and plant geneticist. Her research is notable for its focus on the genetic basis of traits in ecologically valuable plants and on predicting how such plants will respond and adapt to environmental change such as climate warming. She has authored over 100 articles and her works have been cited over 7900 citations. She is honored with being the first female scientist at Brown University to be elected to the National Academy of Sciences.
Ruth Geyer Shaw is a professor and principal investigator in the Department of Ecology, Evolution and Behavior at the University of Minnesota. She studies the processes involved in genetic variation, specializing in plant population biology and evolutionary quantitative genetics. Her work is particularly relevant in studying the effects of stressors such as climate instability and population fragmentation on evolutionary change in populations. She has developed and applied new statistical methods for her field and is considered a leading population geneticist.
Ehab Abouheif, is a Canadian biologist and Professor in the Department of Biology at McGill University. He is a specialist in integrating ecology, evolutionary, and developmental biology of ant societies in order to understand the origins and evolution of complex biological systems. He served as founding President of the Pan-American Society for Evolutionary Developmental Biology, as well as co-founder for the McGill Centre for Islam and Science.
Christine M. Drea is a researcher and professor of biology and ecology with a specialty in animal social behavior and sexual differentiation at Duke University, both primarily on hyenas and primates. Drea's work is focused on female dominant species and the hormonal activity, reproductive development, and social interactions of these animals. She is currently the Earl D. McLean Professor of Evolutionary Anthropology within the Trinity College of Arts & Sciences and the director of graduate studies for the Duke University Ecology program.
Adriana Darielle Mejía Briscoe is an American evolutionary biologist and Professor of Ecology and Evolutionary Biology at the School of Biological Sciences at the University of California, Irvine. She specializes in research questions at the intersection of sensory physiology, color vision, coloration, animal behavior, molecular evolution, and genomics.
Invasion genetics is the area of study within biology that examines evolutionary processes in the context of biological invasions. Invasion genetics considers how genetic and demographic factors affect the success of a species introduced outside of its native range, and how the mechanisms of evolution, such as natural selection, mutation, and genetic drift, operate in these populations. Researchers exploring these questions draw upon theory and approaches from a range of biological disciplines, including population genetics, evolutionary ecology, population biology, and phylogeography.
