“We believe that, like modern apes, the common ancestor of chimpanzees and humans also slept in the trees 6 million years ago,” said Dr Koops. “However, these nests are not preserved in the fossil or archaeological record, so it is impossible to study directly the ancient transition from...
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 ...
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(...
Neanderthals and ancient humans are not anymore two species that exchange chunks of DNA, rather become a single, novel cluster of extant hominins that must be considered by itself. The novel converging, non-ultrametric phylogenetic trees permit the calibration of molecular clocks with a twofold ...

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 ...
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...
I mean, my cousin and I both share a grandparent. But the family tree doesn’t stop there. We also share that grandparent’s grandparents. What about the species that diverged to give rise to the common ancestor of monkeys and humans?且慢!如果真的是这样,那我们的祖先不是也有着共同祖先?
Around the Edo period, kodama lost their rank as gods of the forest and were included as just one of Japan’s ubiquitous yokai. Kodama became humanized as well—there are stories of kodama falling in love with humans and taking human shape in order to marry their beloved. ...
