自然發(fā)生說認(rèn)為人是由自然界的某種物質(zhì)形成的。在中國有傳說：盤古開天辟地后，他身上的蟲子變成了地上的黎民百姓；漢代劉安編的《淮南子》和王充著的《論衡》中都認(rèn)為人是由氣生的；印第安人和毛利人中流傳著以天為父、以地為母的傳說。自然發(fā)生說雖然還帶著神靈的氣息，但已經(jīng)將目光看向了自然。自然發(fā)生說認(rèn)為人是由自然界的某種物質(zhì)形成的12

動物祖先說認(rèn)為人是由動物變化來的，或者是神同某種動物通婚后的后代。在原始人的眼中，圖騰就是他們的祖先。古希臘有的民族認(rèn)為人是從魚慢慢演變來的，有的認(rèn)為他們的祖先是天鵝，有的則認(rèn)為他們的祖先是牛。美洲土著人中也流傳著各種動物祖先的傳說。在西藏同胞中廣泛流傳著人是神女和獼猴結(jié)合的后代的傳說。這種動物祖先說進(jìn)一步拉近了人和神的距離，將人的起源歸結(jié)于生命，這一點跟后來的進(jìn)化論是相通的。動物祖先說認(rèn)為人是由動物變化來的，或者是神13

進(jìn)化論進(jìn)化論的集大成者是英國的博物學(xué)家達(dá)爾文，他在《物種起源》和《人類的由來及其性選擇》中構(gòu)筑了一個生物系統(tǒng)，將進(jìn)化論進(jìn)行到底。按照進(jìn)化論的觀點，物種是由低級向高級進(jìn)化而來的，在原始地球的海洋中，首先出現(xiàn)了原生生物，原生生物分化出了原生植物和原生動物，之后經(jīng)過漫長的時間，逐漸進(jìn)化形成了豐富多彩的動植物。物種不是不變的，所謂屬于同屬的物種，都是某一個已經(jīng)滅亡的物種的直系后代，而不是被分別創(chuàng)造出來的。人是從低等的脊椎動物逐步演化而來的，其演化過程是：魚類→兩棲類→爬行類→哺乳類→人類。人類是從類人猿進(jìn)化而來的，那些從森林遷徙到平原的類人猿經(jīng)過漫長的歷史過程，逐步進(jìn)化成了現(xiàn)代人，這個過程經(jīng)過了臘瑪古猿、南方古猿、直立人、早期智人、晚期智人五個階段。進(jìn)化論進(jìn)化論的集大成者是英國的博物學(xué)家達(dá)爾14

大爆炸理論(theBigBang)誕生于20世紀(jì)20年代，是關(guān)于宇宙形成的最有影響的一種學(xué)說，也稱為大爆炸宇宙論。1927年，比利時天文學(xué)家和宇宙學(xué)家勒梅特（GeorgLema?tre）首次提出了宇宙大爆炸假說。1946年美國物理學(xué)家伽莫夫正式提出大爆炸理論，認(rèn)為宇宙由大約140億年前發(fā)生的一次大爆炸形成。大爆炸理論(theBigBang)誕生15ScientificVersionScientificVersion16一.單詞變形一.單詞變形17一.單詞變形一.單詞變形18

自然發(fā)生說認(rèn)為人是由自然界的某種物質(zhì)形成的。在中國有傳說：盤古開天辟地后，他身上的蟲子變成了地上的黎民百姓；漢代劉安編的《淮南子》和王充著的《論衡》中都認(rèn)為人是由氣生的；印第安人和毛利人中流傳著以天為父、以地為母的傳說。自然發(fā)生說雖然還帶著神靈的氣息，但已經(jīng)將目光看向了自然。自然發(fā)生說認(rèn)為人是由自然界的某種物質(zhì)形成的107

動物祖先說認(rèn)為人是由動物變化來的，或者是神同某種動物通婚后的后代。在原始人的眼中，圖騰就是他們的祖先。古希臘有的民族認(rèn)為人是從魚慢慢演變來的，有的認(rèn)為他們的祖先是天鵝，有的則認(rèn)為他們的祖先是牛。美洲土著人中也流傳著各種動物祖先的傳說。在西藏同胞中廣泛流傳著人是神女和獼猴結(jié)合的后代的傳說。這種動物祖先說進(jìn)一步拉近了人和神的距離，將人的起源歸結(jié)于生命，這一點跟后來的進(jìn)化論是相通的。動物祖先說認(rèn)為人是由動物變化來的，或者是神108

進(jìn)化論進(jìn)化論的集大成者是英國的博物學(xué)家達(dá)爾文，他在《物種起源》和《人類的由來及其性選擇》中構(gòu)筑了一個生物系統(tǒng)，將進(jìn)化論進(jìn)行到底。按照進(jìn)化論的觀點，物種是由低級向高級進(jìn)化而來的，在原始地球的海洋中，首先出現(xiàn)了原生生物，原生生物分化出了原生植物和原生動物，之后經(jīng)過漫長的時間，逐漸進(jìn)化形成了豐富多彩的動植物。物種不是不變的，所謂屬于同屬的物種，都是某一個已經(jīng)滅亡的物種的直系后代，而不是被分別創(chuàng)造出來的。人是從低等的脊椎動物逐步演化而來的，其演化過程是：魚類→兩棲類→爬行類→哺乳類→人類。人類是從類人猿進(jìn)化而來的，那些從森林遷徙到平原的類人猿經(jīng)過漫長的歷史過程，逐步進(jìn)化成了現(xiàn)代人，這個過程經(jīng)過了臘瑪古猿、南方古猿、直立人、早期智人、晚期智人五個階段。進(jìn)化論進(jìn)化論的集大成者是英國的博物學(xué)家達(dá)爾109

大爆炸理論(theBigBang)誕生于20世紀(jì)20年代，是關(guān)于宇宙形成的最有影響的一種學(xué)說，也稱為大爆炸宇宙論。1927年，比利時天文學(xué)家和宇宙學(xué)家勒梅特（GeorgLema?tre）首次提出了宇宙大爆炸假說。1946年美國物理學(xué)家伽莫夫正式提出大爆炸理論，認(rèn)為宇宙由大約140億年前發(fā)生的一次大爆炸形成。大爆炸理論(theBigBang)誕生110ScientificVersionScientificVersion111一.單詞變形一.單詞變形112一.單詞變形一.單詞變形113
