Dalam biologi evolusi dan uji kaji, bidang evolusi uji kaji adalah berkenaan dengan hipotesis dan teori evolusi, dengan penggunaan uji kaji terkawal]]. Evolusi mungkin diperhatikan di makmal sebaik populasi beradaptasi terhadap keadaan persekitaran baharu dan/atau perubahan oleh proses stokastik seperti hanyutan genetik rawak. Dengan peralatan molekul moden, penentuan mutasi yang terhadapnya pemilihan bertindak adalah mungkin, yang membawa kepada adaptasi, dan untuk mencari cara tepat mutasi ini berfungsi. Kerana bilangan besar generasi yang diperlukan untuk adaptasi berlaku, uji kaji evolusi biasanya dijalankan dengan mikroorganisma seperti bakteria, ragi atau virus.[1][2] Walau bagaimanapun, kajian makmal dengan rubah[3] dan dengan rodensia telah menunjukkan bahawa adaptasi ketara boleh berlaku dalam sedikit 10-20 generasi dan uji kaji dengan ikan gupi liar telah diperhatikan dalam bilangan generasi sebanding.[4]
