It was suggested that close contact between humans and monkeys that were kept as pets or hunted for food had allowed the SIVs to jump hosts. More information on HIV can be found on this Wikipedia page. In this tutorial you will use molecular phylogenetics to determine the evolutionary ...
Networks and genealogical treesIn a population with haploid reproduction any individual has a single parent in the previous generation. If all genealogical distances among pairs of individuals (generations from the closest common ancestor) are known it is possible to exactly reconstruct their genealogical...

The genusAdansonia, better known as the baobabs and ‘mother of the forest’1, has captivated botanists, tourists, naturalists and passers-by for centuries. Probably the earliest record of humans marvelling at these amazing trees can be traced back to the Ancient Egyptians, around 2,300 bc(...

The state space of probabilistic models of gene tree topologies at sequences of locations along a genome — as in recent genomic studies of humans, chimpanzees, and gorillas (Hobolth et al., 2007, Dutheil et al., 2009) — can also be described using coalescent histories (Degnan and ...
side of the figure, humans and rhesus monkeys are seen to be more closely related to each other than either is to thehorse. Stated another way, this tree shows that the last common ancestor to all three species lived in a more remote past than the last common ancestor to humans and ...
Based on this evidence, biologists came up with a plausible explanation: infected bats and uninfected civets came into contact at a market, the virus was transmitted to civets and then multiplied and evolved in civets in the public market, until eventually the virus hopped to humans—perhaps ...
Yet, the ambiguous phrase heard in many classrooms is ‘humans didn’t evolve from monkeys’. Tree thinking and lineage thinking are different, yet only refer to different aspects of the phylogenetic process, even if integrating them has proved difficult for many biologists, as displayed in their...
