什么因素可以阻止種群間基因交流呢？由此可引出隔離的概念。學(xué)生初步理解隔離的概念之后，可以安排學(xué)生討論隔離的各種可能的方式，教師歸納出隔離的類型。然后組織學(xué)生閱讀分析教材中的“資料分析”，組織討論“資料分析”中提出的幾個(gè)問題。最后教師應(yīng)強(qiáng)調(diào)，一般情況下，地理隔離是生殖隔離的先決條件，生殖隔離一旦形成，原來屬于一個(gè)物種的兩個(gè)種群，就成了兩個(gè)物種。關(guān)于“共同進(jìn)化與生物多樣性的形成”內(nèi)容的教學(xué)，可以學(xué)生自學(xué)為基礎(chǔ)，教師提出一些具有啟發(fā)性的問題，師生共同歸納總結(jié)的方式推進(jìn)教學(xué)過程。使學(xué)生理解共同進(jìn)化的含義，無機(jī)環(huán)境的變化、無機(jī)環(huán)境的復(fù)雜化和多樣化、有性生殖的出現(xiàn)和生態(tài)系統(tǒng)結(jié)構(gòu)的復(fù)雜化和多樣化對(duì)生物多樣性形成的作用。最后，組織學(xué)生討論生物進(jìn)化理論在發(fā)展。

一,說教材1. 教材的地位和作用本章課程的核心是介紹現(xiàn)代生物進(jìn)化理論.生物進(jìn)化理論的發(fā)展和其他科學(xué)理論的發(fā)展一樣,不是簡(jiǎn)單的新理論對(duì)舊理論的否定和排斥,而是新理論對(duì)舊理論的修正,深入和擴(kuò)展.從拉馬克的進(jìn)化學(xué)說到達(dá)爾文的自然選擇學(xué)說,以及現(xiàn)代進(jìn)化理論的由來,大體都走過了這樣的軌跡.這些應(yīng)該成為處理本節(jié)教學(xué)內(nèi)容的基本脈絡(luò).本節(jié)內(nèi)容包括:拉馬克的進(jìn)化學(xué)說,達(dá)爾文的自然選擇學(xué)說和達(dá)爾文以后生物進(jìn)化理論的發(fā)展,其中重點(diǎn)是達(dá)爾文的自然選擇學(xué)說.生物進(jìn)化論不僅是生物學(xué)中具有重要地位的基礎(chǔ)理論,也是對(duì)人們的自然觀和世界觀有著重要影響的理論.學(xué)生通過本章內(nèi)容的學(xué)習(xí),不僅可以了解生物進(jìn)化理論在達(dá)爾文之后的發(fā)展,進(jìn)一步樹立生物進(jìn)化的觀點(diǎn)和辯證唯物主義觀點(diǎn),而且能夠通過學(xué)習(xí)進(jìn)化理論的發(fā)展過程,加深對(duì)科學(xué)本質(zhì)的理解和感悟.
