At least 74 species of Iranian wildlife are on the red list of the International Union for the Conservation of Nature, a sign of serious threats against the country’s biodiversity. The Iranian Parliament has been showing disregard for wildlife by passing laws and regulations such as the act that lets the Ministry of Industries and Mines exploit mines without the involvement of the Department of Environment, and by approving large national development projects without demanding comprehensive study of their impact on wildlife habitats.
The Iranian Parliament passes legislation without the involvement of what department to the detriment of wildlife?
Department of Environment

Dryer and rockier uplands and ridges are occupied by oak-chestnut type forests dominated by a variety of oaks (Quercus spp.), hickories (Carya spp.) and, in the past, by the American chestnut (Castanea dentata). The American chestnut was virtually eliminated as a canopy species by the introduced fungal chestnut blight (Cryphonectaria parasitica), but lives on as sapling-sized sprouts that originate from roots, which are not killed by the fungus. In present-day forest canopies chestnut has been largely replaced by oaks.
What trees are typically found in the dryer portions?
oak

A more recent study by science historian John van Wyhe has determined that the idea that Darwin delayed publication only dates back to the 1940s, and Darwin's contemporaries thought the time he took was reasonable. Darwin always finished one book before starting another. While he was researching, he told many people about his interest in transmutation without causing outrage. He firmly intended to publish, but it was not until September 1854 that he could work on it full-time. His estimate that writing his "big book" would take five years was optimistic.
Which scientist's study theorized that the idea of Darwin's work being delayed dates to the 1940s?
