According to Darwin gradual accumulation of small variations gives rise to new species. Abrupt mutations do not give rise to new species . Plants arose by gradual adaptation to diverse habitats and not suddenly on earth. Seeded plants are just one group in the plant kingdom.

Long periods of evolutionary changes:
- Diversification in plant life is primarily attributed to long periods of evolutionary changes.
- Over millions of years, plants have undergone various adaptations and modifications to survive and thrive in different environments.
- Natural selection and genetic mutations have played a significant role in shaping the diversity of plant species we see today.
Gradual development of new traits:
- Through gradual changes in their genetic makeup, plants have developed new traits that allow them to better compete for resources, resist diseases, and adapt to changing climates.
- These accumulated changes over time have led to the vast array of plant species with unique characteristics and features.
Environmental factors influencing diversification:
- Environmental factors such as climate, soil composition, and availability of sunlight have also contributed to the diversification of plant life.
- Plants have evolved specific adaptations to thrive in different habitats, leading to the development of various plant forms and structures.
Seed dispersal and colonization:
- Seed dispersal has also played a crucial role in the diversification of plant life.
- By dispersing seeds to new locations, plants have been able to colonize different habitats and evolve in isolation, leading to the emergence of new species.
In conclusion, diversification in plant life has occurred due to long periods of evolutionary changes driven by natural selection, genetic mutations, environmental factors, and seed dispersal. This gradual process has resulted in the rich diversity of plant species we observe today.
