- 1. Analyzed 15,836 ancient genomes from western Eurasia.
- 2. Identified 479 variants under strong directional selection.
- 3. Evolution accelerated over past 10,000 years post-agriculture.
Ancient-genome study led by Harvard's David Reich analyzed 15,836 genomes from western Eurasia. The team sequenced over 10,000 new samples. They spotted 479 variants under strong selection over 10,000 years, per Reich et al. in Nature (2024). Evolution accelerated post-agriculture.
Reich noted dramatic frequency shifts in two-thirds of variants. These tied to diseases and traits like height and immunity.
AI processed the vast datasets. Machine learning detected signals missed by manual methods. Bangladesh leverages these for biotech gains.
Human Evolution Pressures from Ancient-Genome Study
A multiple sclerosis risk variant surged 6,000 years ago. It later declined in some Europeans over 2,000 years, per Reich's Nature paper.
Tuberculosis susceptibility dropped over 3,000 years. HIV resistance rose between 6,000 and 2,000 years ago. Male pattern baldness causes fell over 7,000 years.
These patterns upend steady evolution views since Homo sapiens emerged 200,000-300,000 years ago. Neolithic farming 10,000 years ago drove changes. Bronze Age shifts 5,000 years ago added pressure. AI handled petabytes of data.
Genomics AI Powers Key Discoveries
AI shines in variant calling from degraded ancient DNA. Deep learning predicts allele frequencies. It beats traditional stats on noisy samples, as Nature reports.
Dhaka University labs use machine learning for local pathogens, per university 2023 reports. This builds low-cost capacity.
Dhaka Medical College applies AI to regional genomes. It fills South Asian gaps, cited by Bangladesh Bureau of Statistics (BBS, 2024).
Bangladesh Agricultural Research Institute (BARI, 2023) trials confirm genomics boosts crops.
