The most important source of variability in bacteria is mutation.
There would be less genetic variation in humans

If the human population was reduced to a very small number of interbreeding individual then this small population, denied outbreeding, would have very little genetic variation. Humans, who went through a bottleneck event about 70,000 years ago, are considered a " small " species because they have little genetic variation in comparison to many other species. Google cheetah to see how this concept works.
It takes many generations for humans to mature, grow, and die making them not the ideal subject for genetic analysis because there lifetimes are so long.

The two main sources of genetic variation are mutations, which are changes in the DNA sequence, and recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. These processes contribute to genetic diversity within populations.
For genetic variation to take place
The same reason some humans do. Genetic variation

Humans have lower genetic variation compared to other species due to the bottleneck effect experienced in human evolution. This is because human populations are relatively small and have undergone significant reductions in genetic diversity.

Humans do not have the same genetic information as someone else because each individual inherits a unique combination of genes from their parents. This genetic variation results from the random assortment of genes during sexual reproduction and can lead to differences in traits, characteristics, and susceptibility to diseases among individuals.

Yes, genetic drift has played a role in shaping the diversity and evolution of humans. It has influenced the genetic variation within different human populations over time. In small or isolated populations, genetic drift can have a larger impact on diversity due to random changes in allele frequencies.

Cryptosporidium is not a bacteria; it is a protozoan parasite. It can cause gastrointestinal illness in humans and animals through contaminated food or water sources.
