Made up of 27 million people from 70,000 generations, it dates back up to two million years
An international team of scientists has created the largest family tree of humanity to date. This network, which tracks with unprecedented precision how individuals around the world are related to each other, is made up of 27 million people over 70,000 generations, stretching back to the dawn of humankind. To do this, the researchers have used 4,000 modern genomes from 215 different populations and samples from several ancient individuals, including Neanderthals and a Denisovan. Published this Thursday in the journal ‘Science’, the study provides information on key events in our history, such as migration out of Africa.

This fungus grows buried in the ground and it is necessary to have a trained animal to find it.
Truffles are subterranean or hypogeal fungi of the Ascomycetes class and the Tuber genus. They are globular, rough, and irregular in appearance, resembling a tubercle and of a size that ranges between three and six centimeters. Its weight is variable, between 20 and 200 g.

The strange organism could be a ‘missing link’ between prokaryotic and eukaryotic cells
When we talk about bacteria, we normally think of tiny creatures impossible to see without a microscope. But that doesn’t work for a newly discovered bacterium in the mangroves of the Caribbean. One whose size is so huge that it can be seen with the naked eye. In fact, it can reach 2 cm in length. That is, about 5,000 times larger than any of its congeners. And furthermore, this true giant of the world of bacteria has a huge genome that does not float freely inside the cell, as is usual in the others but is enclosed in a membrane, something that is characteristic of much more advanced cells. and complex, such as those that make up the human body.
