The process you're describing is known as **speciation**, which often occurs through a gradual process of evolutionary change. This can involve several mechanisms, but the concept you might be referring to is **gradualism**, which is a model that explains how species evolve through slow and incremental changes over long periods of time.
Here are some key concepts related to this process:
1. **Microevolution**: This refers to small-scale evolutionary changes within a population, such as changes in allele frequencies. These changes can accumulate over time, leading to larger differences.
2. **Natural Selection**: This is a key mechanism of evolution where individuals with favorable traits are more likely to survive and reproduce, passing those traits to the next generation. Over time, this can lead to significant changes in a population.
3. **Genetic Drift**: This is a mechanism of evolution that occurs due to random changes in allele frequencies, particularly in small populations. Genetic drift can lead to significant changes over generations.
4. **Speciation Events**: As changes accumulate, populations may diverge enough that they can no longer interbreed, leading to the formation of new species. This can occur through:
- **Allopatric Speciation**: When populations are geographically separated, leading to divergent evolution.
- **Sympatric Speciation**: When populations are within the same geographic area but evolve differences that prevent interbreeding.
5. **Fossil Record and Transitional Forms**: The fossil record provides evidence of gradual changes and transitional forms that illustrate how one species gradually evolves into another over millions of years.
6. **Adaptive Radiation**: This occurs when a single ancestral species rapidly diversifies into a wide variety of forms to adapt to different environments or niches.
Overall, the process of slow changes leading to the development of a new species is a fundamental concept in evolutionary biology, illustrating how life on Earth has diversified over time.
