通常,人们总以为昆虫长翅膀是为了飞翔,然而这还是以后的事。科学家的研究结果表明:昆虫最初萌生翅膀并不是为了飞翔,而是为了采热。昆虫原始的翅膀雏型仅是些不大的瓣状物,当周围的气温下降时,这些瓣状物能够帮助昆虫的机体更多地吸收太阳的热量,从而来适应环境的变化。 Often, people always think that insects have long wings to fly, but this is still something to do. Scientists' findings show that insects are not the first to sprout wings to fly, but to heat. Insects primitive wing prototype is only small petals, when the ambient temperature drops, these petals can help the insect body to absorb more sun heat, so as to adapt to environmental changes.
