Introgressed mitochondrial fragments from archaic hominins alter nuclear genome function in modern humans 🏺🧪

Findings highlight an underappreciated mechanism by which archaic mitochondrial fragments shape nuclear genome function and evolution.

Genetic and linguistic structure in East Africa. Principal Component Analysis (PCA) computed for a dataset including genotype array data of many Eastern African and neighboring populations. Samples are colored by population or country. Shapes define language families.

Early Permian Reptile Resting Trace Preserving Scale Impressions And A Possible Cloacal Opening.

It’s functional... but it's unglamorous.
It’s a butthole.

It’s also a weirdly useful clue about how early reptiles were built.

This adaptation precedes the main phases of the early Permian global warming and aridification and probably enabled the diversification of stem reptiles.

A scanning electron micrograph shows the planktic foraminifer Parvularugoglobigerina eugubina. Its appearance about 6,400 years after the Chicxulub impact defines the upper boundary of the first planktic foraminiferal biozone following the K/Pg mass extinction.

New species evolved within a few thousand years of the Chicxulub Impact 🧪

The immediate aftermath of the K/Pg mass extinction (ca. 66 Ma) in the marine realm was characterized by the initial recovery of productivity and the originations of new species.

Maximum-likelihood phylogenetic tree of the heme-copper oxygen reductase family. The tree includes 5360 sequences from all domains of life and shows the recovery of subtype classification grouping, as well as the identification of a group of A2-type within the A-type oxygen reductases.

A new MIT-led study traces an oxygen-using enzyme back billions of years, hinting that microbes “ate” oxygen long before it filled the air.

Examples of phylogenies indicating pre-LUCA evolutionary events

To understand how the foundational characteristics of life first emerged, we need to be able to study evolutionary history prior to the last universal common ancestor.

Why understanding the tree of life matters

There's no hierarchy in evolution. All species alive today, from chimpanzees to bacteria, are cousins that each have equally long lineages

No animal alive today is ‘primitive’
– why are so many still labeled that way? 🧪

The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity. - Albert Einstein

Yeah, you're absolutely right on both counts.

One, if this is so critical it should be made unblockable.
