There was something very strange about these crayfish. They were all female, and they all laid hundreds of eggs without mating. These eggs, in turn, hatched into hundreds more females -- with each one growing up fully able to reproduce by herself. In 2003, scientists sequenced their DNA and confirmed what many owners already believed to be the case: Each baby crayfish was a clone of its mother, and they were filling Europe's fishtanks at alarming speed. Just 25 years ago, the marbled crayfish did not exist at all. Now, they can be found in the wild by the millions in Germany, the Czech Republic, Hungary, Croatia, the Ukraine, Japan, and Madagascar.

South Korea remained the global-innovation gold medalist for the fifth consecutive year. China moved up two spots to 19th, buoyed by its high proportion of new science and engineering graduates in the labor force and increasing number of patents by innovators such as Huawei Technologies Co. Japan, one of three Asian nations in the top 10, rose one slot to No. 6. France moved up to ninth from 11th, joining five other European economies in the top tier. Israel rounded out this group and was the only country to beat South Korea in the R&D category. South Africa and Iran moved back into the top 50; the last time both were included was 2014. Turkey was one of the biggest gainers, jumping four spots to 33rd because of improvements in tertiary efficiency, productivity and two other categories. The biggest losers were New Zealand and Ukraine, which each dropped four places. The productivity measure influenced New Zealand's shift, while Ukraine was hurt by a lower tertiary-efficiency ranking.
