  • Stemming from Mayr's (1942; 1954) concept of the "founder principle", Carson (1968; 1971; 1973; 1975) hasdeveloped a somewhat unorthodox theory of speciation. Briefly, Carson views the steps in species formation as follows. A population undergoes a rapid expansion ("flush") due to temporarily permissive conditions or sudden genotype changes due to migrants or newly arisen variants. This newly expanded population colonzies areas previously unoccupied by the species. Many of the newly colonized… CONTINUE READING
