Tang and his colleagues went to Liaoning, China, to collect samples from the 1-billion-year-old Nanfen formation because they knew this ancient rock is well-preserved and might contain fossils of early complex cells.
But Tang’s discovery provides strong support for the rival idea that green seaweeds evolved in the oceans very early, and gave rise to the plants that evolved to live on land starting around 450 million years ago.
The evolution of plants began long before all this – around 2.3 billion years ago with the rise of simple cells capable of using the green pigment chlorophyll for photosynthesis.
Around two billion years ago, a complex single-celled organism swimming around in the oceans engulfed cyanobacteria and formed a symbiotic relationship with them.
Tang’s finding shows this happened more than 1 billion years ago in the lineage that gave rise to green plants – some previous estimates had put it as late as 620 million years ago.
A study published in the journal Personality and Social Psychology Bulletin sorted sorority or fraternity members into groups of four, and asked them to read interviews in a murder investigation and guess the correct suspect.
Innovating and adapting are hugely important parts of business, and according to Rock, the best way companies can ensure they do this is by hiring more women and culturally diverse team members.
A study from journal Innovation: Management, Policy & Practice analyzed the gender diversity of research and development teams from 4,277 companies in Spain.
Another study from journal Economic Geography gathered data on 7,615 firms from the London Annual Business Survey to show that businesses run by culturally diverse teams were more likely to create new products than homogeneous ones.
