Furthermore, evidence exists that hunting may have been one of the multiple environmental factors leading to extinctions of the holocene megafauna and their replacement by smaller herbivores. North American megafauna extinction was coincidental with the Younger Dryas impact event, possibly making hunting a less critical factor in prehistoric species loss than had been previously thought. However, in other locations such as Australia, humans are thought to have played a very significant role in the extinction of the Australian megafauna that was widespread prior to human occupation.
What event was coincidental with the North American megafauna extinction?

The popularity of superhero comic books declined following World War II, while comic book sales continued to increase as other genres proliferated, such as romance, westerns, crime, horror, and humour. Following a sales peak in the early 1950s, the content of comic books (particularly crime and horror) was subjected to scrutiny from parent groups and government agencies, which culminated in Senate hearings that led to the establishment of the Comics Code Authority self-censoring body. The Code has been blamed for stunting the growth of American comics and maintaining its low status in American society for much of the remainder of the century. Superheroes re-established themselves as the most prominent comic book genre by the early 1960s. Underground comix challenged the Code and readers with adult, countercultural content in the late 1960s and early 1970s. The underground gave birth to the alternative comics movement in the 1980s and its mature, often experimental content in non-superhero genres.
Which genre of comic books had parents concerned?
A: crime and horror

Evidence from the early technical literature concerning electrical recording suggests that it wasn't until the 19421949 period that there were serious efforts to standardize recording characteristics within an industry.
