Introduction

We have many ancestors

Patterns in our DNA

From the pattern to the process

Morphological differences

Each group harbours extensive diversity

Analyses of morphological traits

The problem with morphological traits

Estimating variances from sequence comparisons

Variation within and between populations

Independent studies yield vey similar results

What does this mean in practice?

Mind the numbers

Clustering genotypes or haplotypes

Structures inferred from SNPs, haplotypes, CNV

The problem with genetic traits

Continent specific alleles

The association of alleles in long haplotypes

Genetic diversity outside Africa

How is the human population structured?

Models of human evolution

A model of isolation by distance

Evidence for dispersal from Africa

Genetic diversity reflects patterns of migration

Human evolution and variation (1)

Human evolution and variation (2)

Human evolution and variation (3)

Linguistic and genetic differences are correlated

Serial coalescent simulation and ABC

Reconstructing the maternal genealogy (1)

Reconstructing the maternal genealogy (2)

An example

Mutation

First DNA sequence of a Neandertal

Neandertals not modern Europeans' ancestors (1)

Neandertals not modern Europeans' ancestors (2)

Why is the human population structured this way?
