For decades, scientists have relied on tree rings to estimate how long trees can live. But new research suggests that this widely used method may have been underestimating the lifespan of many ...

A tree of life based on genes from across the nuclear genome and containing nearly 60% of all angiosperm genera unveils the complex evolutionary history of flowering plants. This tree both ...

Flowering plants (angiosperms) are the largest, most diversified, and most successful major lineage of green plants, with ~330,000 known species. In the past decade, the accelerated development of ...

The flowering plant tree of life, much like our own family tree, allows us to understand how different species are related to each other. The tree of life is revealed by comparing DNA sequences ...

International Journal of Plant Sciences, Vol. 180, No. 2 (FEBRUARY 2019), pp. 93-127 (35 pages) Premise of research. Small angiosperm fossils are diverse in Early Cretaceous mesofossil floras from ...

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results ...

This cross section of a sequoia in Yosemite National Park in California has markers identifying the dates of tree rings. Jared Farmer What and where are the oldest known trees on the planet? If you ...

Researchers at Michigan Technological University have discovered a gene that may have played a key role in the evolution of hardwood trees such as oaks and maples. Their work is featured on the cover ...

If you looked up 66 million years ago you might have seen, for a split second, a bright light as a mountain-sized asteroid burned through the atmosphere and smashed into Earth. It was springtime and ...
