Post by: Guido on Apr 23, 2017
All members of the golden hamster species known today are descendants of a single litter collected in Syria in 1939. Its diploid chromosome number is 44. Two other species of hamster, each with a diploid number of 22, overlap geographically in Syria. The golden hamster is thought to be a new species from the mating of a male and female of the two other hamster species. What mechanism might explain this recent event of speciation?
A) Adaptive radiation
B) Formation of a fertile hybrid and halving of the chromosome number of this hybrid
C) Polyploidy
D) Temporal isolation
E) Disruptive selection
