Archaeal species evolved contemporaneously with fungi

Fungi evolved right on track.

Dating of fungal divergences with molecular clocks thus far has yielded highly inconsistent results. The origin of fungi was estimated at between 660 million and up to 2.15 billion y ago, and the divergence of the two major lineages of higher fungi, Ascomycota and Basidiomycota, at between 390 million y and up to 1.5 billion y ago. Assuming that these inconsistencies stem from various causes, w...

Fungi: too evolved to be condemned.

Microsporidia Evolved from Ancestral Sexual Fungi

Microsporidia are obligate, intracellular eukaryotic pathogens that infect animal cells, including humans [1]. Previous studies suggested microsporidia share a common ancestor with fungi [2-7]. However, the exact nature of this phylogenetic relationship is unclear because of unusual features of microsporidial genomes, which are compact with fewer and highly divergent genes [8]. As a consequence...

TWO NEW SPECIES OF MITOSPORIC FUNGI

In the present article, two new mitosporic spccies are introdued, namely: Cercospora fraxinicola Ershad, sp. nov. on Fraxinus rotundifolia and Ramularia rubicola Ershad, sp. nov. on Rubus caesicus.

Novel cooperation experimentally evolved between species.

Cooperation violates the view of "nature red in tooth and claw" that prevails in our understanding of evolution, yet examples of cooperation abound. Most work has focused on maintenance of cooperation within a single species through mechanisms such as kin selection. The factors necessary for the evolutionary origin of aiding unrelated individuals such as members of another species have not been...
