The earliest divergence within the Neognathes was that of the Galloanserae, the superorder containing the Anseriformes (ducks, geese, swans and screamers) and the Galliformes (the pheasants, grouse, and their allies, together with the mound builders and the guans and their allies). The earliest fossil remains of true birds come from the possible galliform Austinornis lentus, dated to about 85 million years ago, but the dates for the actual splits are much debated by scientists. The Aves are agreed to have evolved in the Cretaceous, and the split between the Galloanseri from other Neognathes occurred before the Cretaceous–Paleogene extinction event, but there are different opinions about whether the radiation of the remaining Neognathes occurred before or after the extinction of the other dinosaurs. This disagreement is in part caused by a divergence in the evidence; molecular dating suggests a Cretaceous radiation, while fossil evidence supports a Cenozoic radiation. Attempts to reconcile the molecular and fossil evidence have proved controversial, but recent results show that all the extant groups of birds originated from only a small handful of species that survived the Cretaceous–Paleogene extinction.
Ducks, geese, swans and screamers are part of which group?
****
The answer: Anseriformes


The problem: Answer a question about this article:
In March 2013 Mendes said he would not return to direct the next film in the series, then known as Bond 24; he later recanted and announced that he would return, as he found the script and the plans for the long-term future of the franchise appealing. In directing Skyfall and Spectre, Mendes became the first director to oversee two consecutive Bond films since John Glen directed The Living Daylights and Licence to Kill in 1987 and 1989. Skyfall writer John Logan resumed his role of scriptwriter, collaborating with Neal Purvis and Robert Wade, who returned for their sixth Bond film.[N 4] The writer Jez Butterworth also worked on the script, alongside Mendes and Craig. Dennis Gassner returned as the film's production designer, while cinematographer Hoyte van Hoytema took over from Roger Deakins. In July 2015 Mendes noted that the combined crew of Spectre numbered over one thousand, making it a larger production than Skyfall. Craig is listed as co-producer.
Who directed The Living Daylights and Licence to Kill?
****
The answer: John Glen


The problem: Answer a question about this article:
Chapter VIII addresses the idea that species had special characteristics that prevented hybrids from being fertile in order to preserve separately created species. Darwin said that, far from being constant, the difficulty in producing hybrids of related species, and the viability and fertility of the hybrids, varied greatly, especially among plants. Sometimes what were widely considered to be separate species produced fertile hybrid offspring freely, and in other cases what were considered to be mere varieties of the same species could only be crossed with difficulty. Darwin concluded: "Finally, then, the facts briefly given in this chapter do not seem to me opposed to, but even rather to support the view, that there is no fundamental distinction between species and varieties."
What are Darwin's thoughts on producing hybrids of related species?
****
The answer: the viability and fertility of the hybrids, varied greatly, especially among plants


The problem: Answer a question about this article:
Darwin's aims were twofold: to show that species had not been separately created, and to show that natural selection had been the chief agent of change. He knew that his readers were already familiar with the concept of transmutation of species from Vestiges, and his introduction ridicules that work as failing to provide a viable mechanism. Therefore, the first four chapters lay out his case that selection in nature, caused by the struggle for existence, is analogous to the selection of variations under domestication, and that the accumulation of adaptive variations provides a scientifically testable mechanism for evolutionary speciation.
What is Darwin's belief about the accumulation of adaptive variations?
****
The answer:
the accumulation of adaptive variations provides a scientifically testable mechanism for evolutionary speciation.
