Answer:
Speciation is an evolutionary process by which a new species comes into being. A species is a group of organisms that can reproduce with one another to produce fertile offspring and is reproductively isolated from other organisms. Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. There are a number of different mechanisms that may drive speciation. One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation. A second process called genetic drift describes random fluctuations in allele frequencies in populations, which can eventually cause a population of organisms to be genetically distinct from its original population and result in the formation of a new species.

Answer: c. omnivorous (both meat from hunted large animals and plant foods).
Explanation:
The denture pattern of Australopithecians was like that of the modern humans but there were some specifications which suggests that these were omivorous. Like, the size of the teeth was large, molars were enormous and powerful. Their canines were small and their cheek teeth were larger than the modern humans. These characteristics suggests that they were capable of eating plant foods such as fruits, roots and also meat of other animals.
