1) every large population
2) no emigration or immgration (no gene flow)
3) no mutations: no new alleles added to the gene pool
4) random mating: no sexual selection
5) no natural selection: all genotypes have equal chance at surviving
to answer the question, you must first understand evolution. evolution is the idea that all species are descendants of ancient species that were different from modern day species. basically all living creatures come from one common ancestor. in order for evolution to not occur, means there would be no modified species, species would not develop over time, natural selection and darwins theory would not take place. all creatures would stay the same forever, they would NEVER evolve.
Competition, predation, immagration, emmagration, and an invasive species wiping out another species
1. No Predation
2. No migration
3. No genetic drift
4. No nonrandom mating
5. No mutation

The term 'speciation' does indeed refer to the 'formation' of new species. 'Formation' is probably better replaced with 'divergence' as in 'the divergence of two species from one'. A common ancestor of two species may have two of its populations isolated, so the two populations cannot interbreed. Genetic differences (via mutation) should build up in the two populations over time or indeed, simply the mixing of genes via meiosis within the two populations could follow different routes. The non-mixing of the two populations would ensure the non-homogenisation of the gene pool, ensuring a homogenisation of the morphology of the species back to the morphology of the common ancestor. Eventually, so much genetic difference should build up between the two populations that, be they removed from isolation or not, the two populations would no longer be able to interbreed and produce fertile offspring. Remove the ability of interbreeding and, within the Biological Species Concept, the two populations would have diverged into two separated species. Speciation would have occurred.
The great lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes. Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes. Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia. *Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.
We use non absorbent cotton for plugging of test tubes or other glassware. If we would use absorbent cotton then during sterilization (autoclaving) sterile conditions will not be maintained as cotton will absorb water and microbes will swim from outside to inside. However, non absorbent cotton does not get wet and chances of contamination are decreased significantly.
Guarantee? No. If there is not sufficient variance genetically by recombination and mutation in the immediate environment then nothing will speciate. But geographic barriers are very likely to aid speciation.

Most Middle Easterners are Arab Muslims, but there are significant populations of non-Arabs in the Middle East and significant populations of non-Muslims as well.
