現今已發展許多建構系統發育樹的方法如UPGMA、
neighbor-joining、maximum parsimony 等，所建立系統發育樹可辨別 生物彼此間的親緣關係，但過程中的數值誤差可能會影響發育樹的可 靠性。無論是基於距離的系統發育樹重建方法，還是基於特徵的系統 發育樹重建方法，都不能保證一定能夠得到一棵能描述比對演化歷史 真正的樹，只能做為參考用。
在本研究結果中已推廣了謝與楊系統樹建構法的可行性，也成 功把變形菌綱聚類，之後更深入地研究細菌間的親緣關係以達到更仔 細的分類是必要的，但是對於分類較低層的目或科間區別的適用性，
在未來我們需要更多的時間來研究驗證。
謝與楊系統樹建構法在未來可以加入演化距離，並與其他研究 結果相比可更仔細找出生物間的親緣關係，加入演化距離的過程中可 能需要結合其他建構系統發育樹的方法，並且需要多方面驗證及數據 計算，才有可能達到需要的結果。
