Popper contrasts his views with the notion of the "hopeful monster" that has large phenotype mutations and calls it the "hopeful behavioural monster". After behaviour has changed radically, small but quick changes of the phenotype follow to make the organism fitter to its changed goals. This way it looks as if the phenotype were changing guided by some invisible hand, while it is merely natural selection working in combination with the new behaviour. For example, according to this hypothesis, the eating habits of the giraffe must have changed before its elongated neck evolved. Popper contrasted this view as "evolution from within" or "active Darwinism" (the organism actively trying to discover new ways of life and being on a quest for conquering new ecological niches), with the naturalistic "evolution from without" (which has the picture of a hostile environment only trying to kill the mostly passive organism, or perhaps segregate some of its groups).
Which aspect of organisms changes most radically in the process of evolution Popper envisions?
behaviour

Isambard Kingdom Brunel, the British engineer and railway builder, introduced the idea of a circular bar into the Swindon station pub in order that customers were served quickly and did not delay his trains. These island bars became popular as they also allowed staff to serve customers in several different rooms surrounding the bar.
Who pioneered the circular bar?

Dutch dialects and regional languages are not spoken as often as they used to be. Recent research by Geert Driessen shows that the use of dialects and regional languages among both Dutch adults and youth is in heavy decline. In 1995, 27 percent of the Dutch adult population spoke a dialect or regional language on a regular basis, while in 2011 this was no more than 11 percent. In 1995, 12 percent of the primary school aged children spoke a dialect or regional language, while in 2011 this had declined to 4 percent. Of the three officially recognized regional languages Limburgish is spoken most (in 2011 among adults 54%, among children 31%) and Dutch Low Saxon least (adults 15%, children 1%); Frisian occupies a middle position (adults 44%, children 22%).
