Plant evolution and gravity, new research

Dear Kitty. Some blog

This October 2016 video, in English with Brazilian Portuguese subtitles, says about itself:

Short video explaining a few key facts and concepts on land plant evolution from a phylogenetic perspective.

From the Institute of Science and Technology Austria:

When plant roots learned to follow gravity

Scientists identify key evolutionary steps of gravity-directed root growth

August 2, 2019

Summary: Highly developed seed plants evolved deep root systems that are able to sense Earth’s gravity. The ‘how and when’ of this evolutionary step has, until now, remained unknown. Plant biologists have identified crucial components and processes which only developed in seed plants around 350 million years ago to enable fast and efficient gravity-driven root growth.

One of the most important events in evolutionary history occurred around 500 million years ago with the spread of plant life from water to land. For plants to thrive in this new environment, root systems…
