Humans were on the brink of extinction in the last one million years. Approximately 99% of our ancient human ancestors may have become extinct approximately 930,000 years ago. This critical event led to a significant reduction in the human population, with estimates suggesting that only around 1,300 individuals survived this challenging period, which lasted for about 120,000 years.

Study suggests long-lived #treespecies play greater role in generating #geneticdiversity @elife @elife https://elifesciences.org/reviewed-preprints/88456v1 https://phys.org/news/2023-06-long-lived-tree-species-play-greater.html

Yes, #MexicanGrayWolf is the most #endangered sub species of wolves in the world. They lack #GeneticDiversity & it’s critical for them to be able to pass freely between the US & Mexico. Trump & his #BorderWall put the species into even greater peril. One wolf was observed pacing at the wall for 23 miles, unable to continue south.

#GeneticDiversity in our crops is incredibly important for #FoodSecurity and truly #sustainable #agriculture.

Yesterday M harvested a little plot of an #indigenous variety of #corn he'd planted specifically to reproduce the seed. It turns out the seed was crossed, with very few true to variety cobs being harvested. But so it goes with #OpenPollinated seed sourced from the #campesino #community.

We'll see what he does with this seed. It did produce spectacularly well.
