Recent research on these remarkable fossils and advances in understanding plant developmental genetics are beginning to reveal how major changes in life cycle had an early influence on the
direction of plant evolution.
I'm sure that there were important advances in our
understanding of plant evolution in the last 25 years and that there are paleobotanists out there with thoughtful insights to share.
«Geckos are notoriously described as having incredible ability to adhere to a surface,» said Karl Niklas, professor
of plant evolution at Cornell University and a co-author of the paper.
Researchers from Princeton University and the Chinese Academy of Sciences have posed a
theory of plant evolution based on root adaptations that allowed plants to become more efficient and independent.
Glistening in the humid enclosure are species representing key events during 500 million
years of plant evolution — from primitive liverworts and velvety mosses through horsetails, ferns, and conifers, on up to the flowering plants.
The fossil find, an ancient relative of today's bleeding hearts, poses a new puzzle in the
study of plant evolution: did Earth's dominant group of flowering plants evolve along with its distinctive pollen?
It's a global
view of plant evolution at a time when global rules are essential for building climate models and understanding the biosphere.»
A new theory
of plant evolution suggests that the 400 million - year drive of flora across the globe may not have been propelled by the above - ground traits we can see easily, but by underground adaptations that allowed plants to become more efficient and independent.
By studying liverworts - which diverged from other land plants early in the
history of plant evolution - researchers from the Sainsbury Laboratory at the University of Cambridge have found that the relationship between plants and filamentous microbes not only dates back millions of years, but that modern plants have maintained this ancient mechanism to accommodate and respond to microbial invaders.
«Each of the four institutions involved has its own strengths and these strengths were nicely interwoven to produce a novel
vision of plant evolution.»
In addition to deepening our basic biological
understanding of plant evolution and development, the research offers further avenues for study, including how and why some plants recruit bacteria that impact drought resistance while others don't.
