摘      要：In an essay written by the evolutionary biologist Theodosius Dobzhansky in 1973,he pointed out that Nothing in Biology Makes Sense Except in the Light of Evolution.An interesting phenomenon in biology is the presence of variable numbers of chromosomes in different *** several species,which possess multiple circular chromosomes or simply linear chromosomes (Baril et al. 1989;Suwanto and Kaplan,1989;Jumas-Bilak et al.,1998), most prokaryotes only possess one circular *** contrast,the genomes of eukaryotic species are usually packaged into linear chromosomes with numbers varying from one to hundreds (Crosland and Crozier,1986;Lukhtanov,2015).
