A parasitic relationship is one in which one member of the association benefits while the other is harmed. This is also known as antagonistic or antipathetic symbiosis. Parasitic symbioses take many forms, from endoparasites that live within the host's body to ectoparasites that live on its surface. In addition, parasites may be necrotrophic, which is to say they kill their host, or biotrophic, meaning they rely on their host's surviving. Biotrophic parasitism is an extremely successful mode of life. Depending on the definition used, as many as half of all animals have at least one parasitic phase in their life cycles, and it is also frequent in plants and fungi. Moreover, almost all free-living animals are host to one or more parasite taxa. An example of a biotrophic relationship would be a tick feeding on the blood of its host.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many fungi have at least one parasitic phase in their life cycles?
Ah, so.. unanswerable

The New Zealand police attempted to arrest one of the leaders in the demonstration. When he resisted, a struggle developed between the police and the Mau. The officers began to fire randomly into the crowd and a Lewis machine gun, mounted in preparation for this demonstration, was used to disperse the demonstrators. Chief Tamasese was shot from behind and killed while trying to bring calm and order to the Mau demonstrators, screaming "Peace, Samoa". Ten others died that day and approximately 50 were injured by gunshot wounds and police batons. That day would come to be known in Samoa as Black Saturday. The Mau grew, remaining steadfastly non-violent, and expanded to include a highly influential women's branch.

Ah, so.. unanswerable

The history of biodiversity during the Phanerozoic (the last 540 million years), starts with rapid growth during the Cambrian explosion—a period during which nearly every phylum of multicellular organisms first appeared. Over the next 400 million years or so, invertebrate diversity showed little overall trend, and vertebrate diversity shows an overall exponential trend. This dramatic rise in diversity was marked by periodic, massive losses of diversity classified as mass extinction events. A significant loss occurred when rainforests collapsed in the carboniferous. The worst was the Permian-Triassic extinction event, 251 million years ago. Vertebrates took 30 million years to recover from this event.

Ah, so..
the Cambrian explosion
