Final Answer:

Grasses became prominent in the Neogene.

Step-by-step explanation:

During the Neogene period, which spans from approximately 23 million to 2.6 million years ago, the Earth underwent significant climatic and environmental changes. These changes had a profound impact on plant evolution, and one notable group that flourished during this time was the grass family, Poaceae. Grasses adapted well to the changing conditions of the Neogene, showcasing remarkable resilience and adaptability.

The expansion of grasslands during the Neogene was influenced by several factors. Changes in climate, including a shift towards drier and more open environments, favored the growth of grasses over other plant types. Grasses have unique features, such as C4 photosynthesis, which allows them to efficiently photosynthesize and thrive in arid conditions. This competitive advantage contributed to their prominence during the Neogene, leading to the establishment of vast grassland ecosystems.

Additionally, the evolutionary success of grasses during this period had ecological implications. The spread of grasslands influenced the evolution of herbivores, with many species adapting to a diet based on grass consumption. This interplay between plant and animal life further shaped ecosystems during the Neogene. In conclusion, the adaptability of grasses to changing environmental conditions, coupled with their unique physiological traits, played a pivotal role in making them prominent during the Neogene period.
