[:ja]ランディ・ブレズニク宇宙飛行士がISSから撮影したマダガスカルです。
マダガスカル島は、世界で4番目に大きな島です。先史時代にゴンドワナ超大陸の分裂に伴いアフリカ大陸から分かれ、さらにその後の8800万年前ごろにインド亜大陸とも分離して形成されたとされています。他の大陸と生物種の往来が少ない孤立した状態が長く保たれたため、島内の生態系を構成する各生物種が独特の進化を遂げ、21世紀現在でも野生生物種の90％以上が固有種という、生物多様性にとって重要な場所です。

[Earthview Wonders] No.513: Madagascar🇲🇬
Astronaut Randy Bresnik captured from ISS rugged Madagascar.
Madagascar is the fourth-largest island in the world, and numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian peninsula around 88 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of its wildlife is found nowhere else on Earth.
The local scenery on the ground is as follows.
