People die, and people are born. If the Birth Rate is higher than the Death Rate then population will rise. People move out; for education or work etc., others move in. Industries come and go.
If hybrid offspring have higher fitness than both parental populations, the hybrid zone is likely to expand over time as hybrids outcompete the parental populations. This can result in genetic swamping, where the hybrid gene pool replaces that of the parental species. Over time, this can lead to the eventual fusion of the two parental populations into a single hybrid population.
China and India have populations with over a billion people.
If two populations of a species become isolated, it means that they are separated from each other and cannot interbreed. Over time, this isolation can lead to genetic differences between the populations, potentially resulting in the development of new species through the process of evolution.
The process by which populations accumulate inherited changes over time is called evolution. Evolution occurs through mechanisms such as natural selection, genetic drift, mutation, and gene flow, leading to the gradual change and diversification of species. These inherited changes can result in adaptations that increase the fitness of individuals within a population.
Over time, the populations may become genetically distinct from one another due to accumulation of different mutations. This can lead to the evolution of new species if the genetic differences become significant enough to prevent successful reproduction between individuals from the two populations.

"Chage and Aska" is a popular Japanese duo composed of Chage and Ryo Aska. They were formed in 1979 and are still active to this date, with over 31 million albums and singles sold in Japan.

Change over time in populations of organisms. Or, more formally; the change in allele frequency over time in a population of organisms.

small populations where random events can have a significant impact on allele frequencies over time.
The process that gradually changes populations over time is called evolution. This occurs through genetic variations, natural selection, genetic drift, and other mechanisms that lead to changes in the traits and characteristics of a population over successive generations.
