Artificial Intelligence (AI) used to test evolution’s oldest mathematical model

I cannot claim to be an expert on artificial intelligence (AI) or machine-learning, but I would say that the essence of this approach is as follows: Many things in science (more so in biology than perhaps in chemistry, and even … Continue reading

The population history of northeastern Siberia since the Pleistocene

Far northeastern Siberia was the gateway to the Americas for ancient humans; today it is home to diverse cultures whose members speak many languages. During the Late Pleistocene period [i.e. the Last Glacial Period (LGP), lasting from ~126,000 to ~11,700 … Continue reading

Human CRISPR twins are predicted to have “shortened life spans”

hese GEITP pages have followed the story, the ethical dilemma, of biophysicist Jiankui He (in late 2018, from the Southern Univ of Sci & Technol in Shenzhen, China), who reported births of twin girls whose genomes had been edited using … Continue reading

Make way for the mouse lemur

As these GEITP pages have frequently described, because of the well-established field of mouse genetics (since early 20th-century) and whole-genome sequncing (WGS) of many sublines, mouse research has remained head-and-shoulders above any other animal model, with regard to extrapolation of … Continue reading

Pluripotency and the origin of animal multicellularity

“Evolution of life on Earth” has been among the various topics discussed in these GEITP pages, because gene-environment interactions play a major role in how organisms (all living things) continue to evolve — i.e. in response to advantageous, or adverse, … Continue reading

An archaebacterium that expresses actin protein — a trait thought to be eukaryotie-specific

From time to time, these GEITP pages consider topics on Evolution. In biology, there are six Kingdoms of Life: Archaebacteria, Eubacteria, Protists, Fungi, Plants and Animals. The first two are prokaryotes (microscopic single-celled organisms having unpaired chromosomes and neither a … Continue reading

Dual-spindle formation keeps the two parental genomes apart in 1-cell mammalian embryo

Mammalian life begins with fertilization of the egg. Once the egg and sperm have fused, the parental chromosomes need to be combined. It was previously taught that a single microtubule-spindle is responsible for spatially combining the two genomes, and then … Continue reading

SLE in in leptin transgenic pigs ???

For anyone interested in SLE (systemic lupus erythematosus), this is a weird finding, maybe a paper worth investigating….. Symptoms of systemic lupus erythematosus are diagnosed in leptin transgenic pigs Junchen Chen, Weiqi Zeng, Weirong Pan, Cong Peng, Jianglin Zhang, Juan … Continue reading

The evolution of genome size in maize

The full-length article about “genome size” [attached left pdf file] was shared with all of GEITP on Aug 31st, and that analysis is re-posted furthest below. The editorial commentary [attached right pdf file] was intended to accompany the full-length article. … Continue reading

The prehistoric peopling of Southeast Asia

Anatomically modern humans are known to have expanded into Southeast Asia at least 65,000 years ago –– leading to formation of the Hòabìnhian hunter-gatherer tradition. Although Hòabìnhian foragers are considered to be the ancestors of present-day hunter-gatherers from mainland Southeast … Continue reading
