Summary
This summary is machine-generated.Steppe ancestry arrived in France during the Late Neolithic period, significantly shaping European genomes. Genomic analysis reveals two major admixture pulses linked to the Corded Ware and Bell Beaker cultures.
Area Of Science
- Ancient Genomics
- European Prehistory
- Population Genetics
Background
- The third millennium BCE saw major European cultural and genomic shifts driven by migrations from the Pontic-Caspian steppe.
- These migrations profoundly influenced the genetic makeup of present-day European populations.
Purpose Of The Study
- To analyze high-resolution whole-genome data from Late Neolithic individuals in the Paris Basin.
- To investigate the timing, patterns, and dynamics of steppe ancestry arrival and admixture in France.
Main Methods
- Whole-genome sequencing and haplotype phasing of seven individuals from a collective burial (~2500 BCE) and one Bell Beaker individual (~2300 BCE).
- Genome reconstruction of an unsampled individual using related individuals' data.
- Analysis of admixture patterns and population dynamics.
Main Results
- Direct evidence for the arrival of steppe ancestry in France during the collective burial period.
- Identification of two significant Neolithic/steppe-related ancestry admixture pulses around 3000/2900 BCE and 2600 BCE.
- Reconstruction of early-stage admixture dynamics and propagation of steppe ancestry.
Conclusions
- Steppe ancestry arrived in France during the Late Neolithic, as evidenced by the collective burial.
- The identified admixture pulses correlate with population expansions and cultural complexes like Corded Ware and Bell Beaker.
- This study illuminates the complex genomic landscape of Late Neolithic Europe and the impact of steppe migrations.

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes.
Exon shuffling follows “splice frame rules.” Each exon...
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
