案例简介：@ beverlyjoubert的照片/今天，任何生活在野外的大象都面临着偷猎的威胁-每年都有成千上万的象牙被杀。但是其中有一个进化枝一直特别脆弱: 大象牙。这些标志性的巨人是基因的携带者，它们产生的巨大的长牙几乎伸到地面，这些标志性的巨人一直是备受珍视的目标。曾经在非洲大陆普遍存在，今天只有少数人幸存。我们即将看到太阳落在这些传奇生物身上…… 即将失去可能产生下一代巨人的非凡基因。我们知道我们必须做些什么来确保这不会发生。# 大象 # elephantsoffinstagram # bigtusker # thisismytrophy

案例简介：Photo by @beverlyjoubert / Any elephant alive in the wild today faces the ever-present threat of poaching—tens of thousands are killed for their ivory each year. But there is one clade among them that has always been especially vulnerable: the big tuskers. Bearers of genes that produce massive tusks reaching down to almost brush the ground, these iconic giants have been much-prized targets. Once common across the African continent, only a handful survive today. We are close to seeing the sun set on these legendary creatures … close to losing the extraordinary genes that could produce the next generation of giants. We know what we have to do to make sure this doesn’t happen. #elephants #elephantsofinstagram #bigtusker #thisismytrophy
