However, many scientists think this is a case of sympatric speciation in progress. Speciation is the process by which one species splits into two or more species.

Other scenarios on the list describe behavioral isolation, chemical isolation, and temporal isolation. In other cases, a hybrid can survive to adulthood in good health but is infertile because it can't split its mismatched chromosomes evenly into eggs and sperm. However, that doesn't mean they have to be part of the same interbreeding group in real life. Speciation Development of a new species through a variety of factors Rate of speciation depends on generation time, environmental conditions, etc. **Please watc, NO PREP Sub lesson science article with probability questions OR help practice class content OR use as homework!

Figure 18.1 C. 1: Finches of Daphne Major: A drought on the Galpagos island of Daphne Major in 1977 reduced the number of small seeds available to finches, causing many of the small-beaked finches to die. When the tetraploid plant matures, it will make diploid. Once the populations are separated evolution can occur through multiple mechanisms.

Can sympatric speciation, speciation without geographical separation, occur by mechanisms other than polyploidy? The process of splitting of genetically homogenous population into two or more populations that undergo genetic differentiation and eventual reproductive isolation is called speciation. Presumably, students volition realize that allopatric relies mainly on geographic isolation, but sympatric requires other mechanisms, such equally timing, behaviors, or niche choice.
