Angiosperms did not evolve from gymnosperms, but instead evolved in parallel with the gymnosperms; however, it is unclear as to what type of plant actually gave rise to angiosperms.
Thus, the evolution that produced the plants which were eventually recognized as the angiosperms must have been taking place during the Triassic, Jurassic, and early Cretaceous periods (which span from about 252 million to 100.5 million years ago).
The pollen evidence suggests that the Gnetales, a modern group of gymnosperms closely related to the angiosperms, were present during the Triassic Period (about 252.2 million to 201.3 million years ago).
Also, the relatively short generation time in which the angiosperms reproduce—permitting rapid population growth and easier colonization of disturbed habitats—gave the flowering plants an adaptive advantage over the gymnosperms, which were dominant during the Early Cretaceous.
Did angiosperms come before gymnosperms?
Photo Caption: Gymnosperms, like this Colorado blue spruce, are a group of nonflowering plants that emerged several hundred million years before flowering plants (angiosperms) entered the evolutionary history of the plant kingdom.
Are gymnosperms older than angiosperms?
Gymnosperms are older than angiosperms on the evolutionary scale. They are found far earlier in the fossil record than angiosperms.
Were gymnosperms the first to evolve?
Gymnosperms were the first seed plants to have evolved. The earliest seedlike bodies are found in rocks of the Upper Devonian Series (about 382.7 million to 358.9 million years ago). During the course of the evolution of the seed habit, a number of morphological modifications were necessary.
Are gymnosperms more evolved than angiosperms?
Angiosperms and gymnosperms are the two main categories of the plants. Both are seed-bearing plants having few similarities. This is because of the fact that gymnosperms were present for more than 200 million years before the angiosperms evolved.
When did angiosperms dominate?
The majority of environments are dominated by flowering plants today, but it is uncertain how this dominance originated. This increase in angiosperm diversity happened during the Cretaceous period (ca. 145–65 Ma) and led to replacement and often extinction of gymnosperms and ferns.
How did angiosperms become dominant?
Brodribb and Feild argue that more photosynthesis meant more carbon for growth. And that would have given the angiosperms the energy to push competitors like conifers out of the canopy around 150 million years ago, making angiosperms the most productive group of land plants in the world.
When did flowering plants become dominant?
The first remains of flowering plants are known from 125 million years ago. They diversified extensively during the Early Cretaceous, became widespread by 120 million years ago, and replaced conifers as the dominant trees from 60 to 100 million years ago.
When did angiosperms rise?
Rise of angiosperm-dominated herbaceous floras in forests Our estimate for the time of origin of crown group Ranunculaceae is at c. 108 Ma, the early mid-Cretaceous (Fig. 1), which corresponds to the beginning of the explosive radiation of angiosperms5,6,7,41 and the initial rise of angiosperm-dominated forests20.
Did angiosperms come first?
Molecular evidence suggests that the ancestors of angiosperms diverged from the gymnosperms during the late Devonian, about 365 million years ago, despite only appearing in the fossil record during the Early Cretaceous, almost two hundred million years later.
How old are angiosperms?
Most dates, however, are between 180-140 million years ago, suggesting a Middle Jurassic-Early Cretaceous origin of flowering plants, predating the oldest unequivocal fossil angiosperms by about 45-5 million years.
Where did angiosperms originate from?
The origin of angiosperms is still a mystery. More than one-hundred years ago, Darwin called the origin of angiosperms an “abominable mystery”. Angiosperms appear rather suddenly in the fossil record, with no obvious ancestors for a period of about 80 to 90 million years prior to their appearance.
When did angiosperm originate?
The earliest plants generally accepted to be angiospermous are known from the Early Cretaceous Epoch (about 145 million to 100.5 million years ago), though angiosperm-like pollen discovered in 2013 in Switzerland dates to the Anisian Age of the Middle Triassic (about 247.2 million to 242 million years ago), suggesting …

The biggest difference between gymnosperm and angiosperms lies in their seeds.
