From about 450 to 300 million years ago, bryophytes dominated the earth's vegetation, and then about 300 million years ago, gymnosperms began to become more prominent.
<h3>Evolution of plants</h3>
About 450 to 300 million years ago, most of the plants as we currently have them are yet to evolve according to evolutionists.
Instead, seedless vascular plants such as bryophytes were around. Many years after, these seedless plants evolved into vascular plants with seeds that are not enclosed in fruits.
Vascular plants with seeds but without fruits are known as gymnosperms. Plants whose seeds are enclosed in fruits, angiosperms, evolved thereafter.

Answer:
The correct answer is - Trains can have inconvenient schedules, but produce less pollution than cars do.
Explanation:
Trains are expensive to build and also required land for making routes and stations and platforms for passengers but that can be reimbursed by fare in a longer time period.
Trains also produce pollution but in comparison to cars these are way less contribute to the pollution, However, these are not convenient as they start and reach at a specific time and also sometimes not comfortable like cars.
