Biology – The natural science that studies life. Areas of focus include structure, function, growth, origin, evolution, distribution, and taxonomy.
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.
Behavioral neuroscience, also known as biological psychology, biopsychology, or psychobiology, is the application of the principles of biology to the study of physiological, genetic, and developmental mechanisms of behavior in humans and other animals.
Evolutionary neuroscience is the scientific study of the evolution of nervous systems. Evolutionary neuroscientists investigate the evolution and natural history of nervous system structure, functions and emergent properties. The field draws on concepts and findings from both neuroscience and evolutionary biology. Historically, most empirical work has been in the area of comparative neuroanatomy, and modern studies often make use of phylogenetic comparative methods. Selective breeding and experimental evolution approaches are also being used more frequently.
Theodore Holmes Bullock is one of the founding fathers of neuroethology. During a career spanning nearly seven decades, this American academic was esteemed both as a pioneering and influential neuroscientist, examining the physiology and evolution of the nervous system across organizational levels, and as a champion of the comparative approach, studying species from nearly all major animal groups—coelenterates, annelids, arthropods, echinoderms, molluscs, and chordates.

There is much to be discovered about the evolution of the brain and the principles that govern it. While much has been discovered, not everything currently known is well understood. The evolution of the brain has appeared to exhibit diverging adaptations within taxonomic classes such as Mammalia and more vastly diverse adaptations across other taxonomic classes. Brain to body size scales allometrically. This means as body size changes, so do other physiological, anatomical, and biochemical constructs connecting the brain to the body. Small bodied mammals have relatively large brains compared to their bodies whereas large mammals have a smaller brain to body ratios. If brain weight is plotted against body weight for primates, the regression line of the sample points can indicate the brain power of a primate species. Lemurs for example fall below this line which means that for a primate of equivalent size, we would expect a larger brain size. Humans lie well above the line indicating that humans are more encephalized than lemurs. In fact, humans are more encephalized compared to all other primates. This means that human brains have exhibited a larger evolutionary increase in its complexity relative to its size. Some of these evolutionary changes have been found to be linked to multiple genetic factors, such as proteins and other organelles.
The Mauthner cells are a pair of big and easily identifiable neurons located in the rhombomere 4 of the hindbrain in fish and amphibians that are responsible for a very fast escape reflex. The cells are also notable for their unusual use of both chemical and electrical synapses.
Justin S. Rhodes is an American neuroscientist and a professor in the Department of Psychology at the University of Illinois at Urbana-Champaign. He is affiliated with the Neuroscience Program, Program of Ecology, Evolution, & Conservation Biology, the Carl R. Woese Institute for Genomic Biology, and the Neurotech group at Beckman Institute for Advanced Science and Technology. After receiving a Bachelor of Science in biology at Stanford University, Rhodes obtained a PhD in zoology in 2002 from University of Wisconsin–Madison, under the supervision of Theodore Garland, Jr. After completing a postdoctoral fellowship at Oregon Health & Science University, he held a position as an instructor at Lewis & Clark College for a year before accepting a full-time faculty position in 2005 in the biological division of the Department of Psychology at the University of Illinois. His lab investigates a broad array of topics in the field of neuroscience with particular emphasis in exercise-induced hippocampal neurogenesis, neural circuitry involved in addictive behaviors, and brain plasticity in clownfish.

Marvalee Hendricks Wake is an American zoologist and professor at the University of California, Berkeley, known for her research in the biology of caecilians and vertebrate development and evolution. A 1988 Guggenheim Fellow, she has served as president of the American Institute of Biological Sciences, the American Society of Ichthyologists and Herpetologists, Society for Integrative and Comparative Biology, International Union of Biological Sciences, and the International Society of Vertebrate Morphology. She is a fellow of the American Association for the Advancement of Science and the California Academy of Sciences, and is a member of the American Academy of Arts and Sciences.
David Pafford Crews is the Ashbel Smith Professor of Zoology and Psychology at the University of Texas at Austin. He has been a pioneer in several areas of reproductive biology, including evolution of sexual behavior and differentiation, neural and phenotypic plasticity, and the role of endocrine disruptors on brain and behavior.

She is a paleobiologist who uses big data analytics to study macroevolution. She is a TED Senior Fellow and has two TED talks with almost three million views as of 2022.
Elizabeth L. Brainerd is an American biologist who has contributed to our understanding of the evolution of breathing. and the biomechanics of vertebrates. She is one of the inventors of XROMM, a technique for making 3D movies of internal structure that combines CT scanning with biplanar x-ray movies.

As the Director for Science Communications at UC Davis, Calisi also studies science communication and advocates for inclusivity, equity, and diversity in STEM.
Kanaka Rajan is a computational neuroscientist in the Department of Neurobiology at Harvard Medical School and founding faculty in the Kempner Institute for the Study of Natural and Artificial Intelligence at Harvard University. Rajan trained in engineering, biophysics, and neuroscience, and has pioneered novel methods and models to understand how the brain processes sensory information. Her research seeks to understand how important cognitive functions — such as learning, remembering, and deciding — emerge from the cooperative activity of multi-scale neural processes, and how those processes are affected by various neuropsychiatric disease states. The resulting integrative theories about the brain bridge neurobiology and artificial intelligence.
