Invertebrates (Ray scorpion )had successfully landed before vertebrates .It could have been too late when ichthyostega came onto the land.無脊椎動(dòng)物先于脊椎動(dòng)物登陸.在魚石螈（兩棲動(dòng)物登陸先鋒）登陸之前,雷蝎（古節(jié)肢動(dòng)物）已經(jīng)登陸了.那到底在這四種生物中，那一個(gè)先登陸呢？無脊椎動(dòng)物雷蝎（古節(jié)肢動(dòng)物）先于脊椎動(dòng)物魚石螈（兩棲動(dòng)物登陸先鋒）登陸。 節(jié)肢動(dòng)物就是無脊椎動(dòng)物啊。怎么會(huì)是四種生物呢？
