Human Migration HypothesesHuman Migration Hypotheses
Most scientists agree that an early hominid species evolved in Africa and spread across the Old World. After that, there is still some debate between the èMultiregionalî hypothesis and the èOut of Africa,î or èReplacementî hypothesis as to how modern humans came to evolve and populate the globe.

Mitochondrial DNAMitochondrial DNA
A 3-D animation of the way that a zygote receives nuclear, or genomic, DNA from both parents (sperm and egg cells) but inherits mitochondrial DNA only from the mother.

Mitochondrial EveMitochondrial Eve
This shows how one female ancestor passed on her mitochondrial DNA to everyone living today. This woman, called "Mitochondrial Eve," probably lived only 200,000Œ300,000 years ago.

Regulatory HypothesisRegulatory Hypothesis
This animation illustrates the experiments that Ajit Varki, Wolf Enard, and Svente Paabo carried out to compare the gene expression between chimpanzees, humans, and an outgroup, the Rhesus monkey. While gene expression was similar between humans and chimps in the liver and blood, they showed very different patterns of gene expression in the brain.

Homo habilis skull specimen Homo habilis skull specimen
Human and chimp allele clustering Human and chimp allele clustering
For nearly all genes, human alleles cluster together and chimp alleles cluster together (left). In the case of the major histocompatibility complex (MHC), human alleles are often more closely related to chimp alleles and vice-versa. This occurs due to balancing selection maintaining variation at the MHC (right).

The human "bush," as postulated from fossil finds of hominid species.
Human skull specimen Human skull specimen
Hypotheses of human migration Hypotheses of human migration
Left: The "Out of Africa", or "Replacement," hypothesis suggests all living humans evolved from a group that originated in Africa. Right: The èMultiregionalî hypothesis suggests several groups evolved in parallel to form todayçs population of humans.

Icelandic people have kept careful records of their family histories for hundreds of years, aiding efforts to track disease patterns in their genes.
