The study of evolution in action in nature, by a combination of field work and laboratory genetics. Of a camera, the adjustable opening through which light passes to reach the film. Later he devoted his energies to conservation and politics. An individual having two different alleles at a genetic locus.

The process by which characteristics are passed from one generation to the next. The single-celled eukaryotes once lumped into the kingdom Protista are now known to be very diverse, and not closely related to one another. Synonym of monophyletic group. The study that characterizes genes and the traits they encode.

She is married to Richard Leakey. Humanity and the Biodiversity Crisis. The movement of organisms into an area.

Gases that absorb

Describe your ideal match in one sentence. When no deviation exists, the population is said to be in linkage equilibrium. The electrophoretic motility of a molecule is influenced by its size and electric charge. Also called a fitness surface.

More generally, the genetic profile of an individual. While Lyell initially opposed the idea of evolution, he came to accept it after Darwin published On the Origin of Species. The allele a does not influence the heterozygote's phenotype and is called recessive. This led him to extensive work in computer simulations. The disappearance of a species or a population.

An anatomist, Kimbel worked with Don Johanson and assembled Lucy's skull fragments. The reproductive cells in an organism, or the cells that produce the gametes. Relating to cognition, the mental processes involved in the gathering, organization, and use of knowledge, including such aspects as awareness, perception, reasoning, and judgement.

Species adapt when succeeding generations emphasize beneficial characteristics. His research is concerned with aspects of major evolutionary novelties, particularly the Metazoan radiation and post-mass extinction recoveries. Of genes, present on the same chromosome. The increased difference between two closely related species where they live in the same geographic region sympatry as compared with where they live in different geographic regions allopatry. Darwin and Lyell later became close friends.

Tiny, single-celled, prokaryotic organisms that can survive in a wide variety of environments. Deoxyribonucleic acid, the molecule that controls inheritance. The case in which inheriting two recessive alleles of a gene causes the death of the organism. The study of genes and their relationship to characteristics of organisms.

The process by which molecules for example, of oxygen move passively from a region of high concentration to a region of low concentration. Her primary research interests concern various facets of marine biodiversity.

All the genes in a population at a particular time. Gases that absorb and reradiate infrared radiation. The process during meiosis in which the chromosome of a diploid pair exchange genetic material, visible in the light microscope. His Genetics of Domestic Rabbits, published in by Harvard University Press, covers such topics as the genes involved in determining the coat colors of rabbits and associated mutations. It has been historically influential in classification.
