In some taxa of Hymenoptera, fungi, red algae and mistletoe, parasites and their hosts are either sibling species or at least closely related (Emery's rule). Three evolutionary mechanisms have been ...

Behavior in eusocial insects likely reflects a long history of selection imposed by parasites and pathogens because the conditions of group living often favor the transmission of infection among ...

Today, 150 years after Darwin’s epochal “On the Origin of Species,” many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and ...

The blood fluke may be the ultimate parasite. This ingenious flatworm comes of age inside a tiny snail host before entering its real host—humans—directly through the skin and burrowing into the ...

Molecular biologists have decoded the genome of the Pristionchus pacificus nematode, thereby gaining insight into the evolution of parasitism. They have shown that the genome of the nematode consists ...

IN these lectures the late Prof. Theobald Smith reviewed the knowledge and experience of nearly fifty years of fruitful devotion to research on infective disease in man and animals. The book contains ...

A new genetics study of ant “social parasites” shows how complex sets of features can emerge rapidly and potentially split species. When the researcher Daniel Kronauer was still a postdoc in 2008, he ...

One of the most interesting topics discussed in my Ornithology class was about the “con artists” found in nature… Brood parasitism occurs when a female bird (the parasite) lays her eggs in the nest of ...
