tsob ntoo phylogenetic tsim los ntawm DNA sequences li cas?
Phylogenetic ntoo yog daim duab ntawm evolutionary kev sib raug zoo ntawm cov kab mob. … Raws li cov kab mob evolve thiab diverge, lawv DNA sequences accumulate mutations. Cov kws tshawb fawb sib piv cov kev hloov pauv no siv cov kev sib txuas ua ke kom rov tsim kho keeb kwm evolutionary.
