Even though miniature poodles and labrador retrievers are both part of the same species, canis lupus, they are very different in appearance. the differences can be attributed to macroevolution microevolution comparative morphology a split along lineage

Microevolution

Explanation:

Natural populations exhibit genetic variations. The organisms of the same species share gene pool but differ in their phenotypes due to the inheritance of different alleles. Frequency of an allele increases or decreases over generations and the process is called microevolution. Microevolution is responsible for small changes in allele frequencies which in turn impart the individuals of the same species quite distinct phenotypes.
