PPT-SGN 27 The Origin of Species

Macroevolution describes the origination of new taxonomic groups vs microevolution which deals with change in allele frequency and frequencies of genotype and phenotype What is a species. What is a Species?. Speciation. – the origin of new species. The . biological species concept. defines a species as a population or group of populations whose members have the potential to interbreed with one another in nature to produce viable, fertile offspring, but who cannot produce viable, fertile offspring with members of other species. Macroevolution is essentially the formation of new species (speciation) and accompanying events. . Reproductive isolation can occur in a variety of ways. Reproductive isolation is the key to cladogenic speciation. 北. 京碧水. 源. ). Finance. Learning Objectives. Explain the sources and availability of finance to a . startup. or growing business.
