Human Genetics : Mutations are changes in genetic information stored in cells. Various agents can cause mutations, for example radiation, viruses, and certain chemicals we come into contact with. But mutations are not just the result of damaging influences coming from outside the cells - some are the result of errors made within cells when they make copies of  genetic information before cell division.

TIGR Introduces Vibrio cholerae Genome :
Vibrio cholerae: base pairs: 4,033,460, protein-encoding genes: 3,885
This isn't the first bacterium known to have a second chromosome by any means, but it is the first where the evidence is overwhelming that [the second chromosome] may have come from somewhere else.

Evolution: Selected Papares and Commentary : This is a nice collection of papers, going back to Darwin, that traces the advances from early hyptheses about genetic material to modern knowledge.

Epigenetics: For decades genetic mutations and recombinations have driven most descriptions of how traits are handed down from one generation to another. Discoveries in epigenetics -- heritable changes in gene function that occur without a change in the DNA sequence -- are changing the way researchers think about heredity.

Closer Look at the Genome’s Black Holes : Understanding the basis of the sterility of cross-species breeding has been a problem in evolution ever since Darwin. Rapidly evolving centromeric DNA, histones and their incompatibility with their counterparts in another species might account for this phenomenon.

Genetics Related to Human Organs

Ovarian Kaleidoscope Database : Ovarian activation. The ovaries call on scads of genes to help with their hormone-producing and egg-releasing chores. Information about these genes is scattered throughout online gene and protein databases and scientific publications. The Ovarian Kaleidoscope Database aims to gather all this information in a searchable format.

Globin Gene Server home page : On their Globin Gene Server, Penn State biochemist Ross Hardison, computer scientist Webb Miller, and collaborators are converting two books of the 1000-some known human globin mutations into databases. The Penn State team also recently unveiled a Web tool called PipMaker for comparing DNA sequences. "One of the beautiful aspects," says Hardison, is that PipMaker can align much longer sequences (up to 2 million bases) than most such tools can handle. Penn State - Bioinformatics Group

Human Genetics and the Question of "Race"

Genes, People, and Languages : by Luigi Luca Cavalli-Sforza. This scientist was among the first to ask whether the genes of modern populations contain a historical record of the human species. His book Genes, Peoples and Languages is one of my top recommendations for persons wishing to get a grounding in evolutionary biology.

Luigi Luca Cavalli Sforza - Paper : Drift vs. Natural Selection, Evolutionary Trees, Genetics and Culture, Racism, Political Difficulties Encountered by Genetics, Genetic Future of Humans, Multidisciplinarity and Historical Studies. This is a paper delivered upon the occasion of receiving the Balzan Prize for 1999.

Human Origins and Evolution in Africa : What do we know about human origins and evolution in Africa? Researchers have culled information from many different fields to address this question. This page was established by Professor Jeanne Sept to maintain links to this constantly growing scientific database, and teaching resources for her students.

Genetic Indexing of Race is Irresponsible and Unscientific
Science isn't about what might be true, but about what is true based upon rational methods of inquiry. If an idea can't be demonstrated with rigor or clarity, then it is clearly not better to think it is true.

Race, Genes & Anthropology : One of the most astonishing features of the contemporary discussion of race is the fact that anthropology, the science that deals with human biological and cultural variation, has managed to be marginalized. Regardless of reason, it is clear that there is no consensus and great confusion exists in the discipline [biological anthropology] regarding race.

The Concept of Human Races: Uses and Problems :
The use of stereotyped morphophenotypic races as biologically distinct breeding units has continued despite the scientific ambiguities and inherent assumptions associated with them.

Glossaries, Factoids and General Resources

Topics in Statistical Genetics : The notes available here are draft chapters of a book by Simon Tavare´ and Peter Donnelly entitled Ancestral Processes in Population Genetics.

Evolutionary Genetics – Acquiring New Information

Where do Genes Come From? : Molecular technology allows us to establish the genetic relatedness of different organisms and classify them in a meaningful way. Also, it lets us reconstruct the evolutionary pathways that have led to the appearance of all species of animals or plants living around us today.

Retroviruses Demonstrate Human Evolution : Phylogenies of ancient endogenous retrovirus sequences shows how an ERV locus shared by two or more species is descended from a single integration event, proving that the species share a common ancestor into whose germ line the original integration took place.

Resources for Teachers

Human Genetics : This web page is composed of simple lesson plans and activity ideas created by Jamie Handy. The activities are intended for biology teachers and assume a basic knowledge of Mendelian genetics and probability. Teachers are invited to adapt them in ways that will promote learning in their classrooms.

Mother of the Jumping Gene: Geneticist Barbara McClintock's studies of corn plants revealed that genes can move around on chromosomes and won her a Nobel Prize in 1983, when she was 81. She battled against barriers to women in science. A Cornell University in 1919 women were forbidden from majoring in genetics, so she earned her Ph.D. in botany.

A History of Genetics : by A. H. Sturtevant. A Cold Spring Harbor electronic text.

Non-human Species Genomic Information
