Genetic Legacy of North Africa in Iberia

 



Recent studies highlight the deep-rooted genetic connections between Iberia and North Africa. This relationship persisted for centuries until event in history altered it. Researchers analysed ancient DNA from individuals in eastern Spain to understand this genetic lineage, particularly during the periods of Al-Andalus and the Reconquista.

Historical Context of Iberia

Iberia, comprising modern Spain and Portugal, has a complex history influenced by various cultures. From Greek and Roman settlements to the Islamic conquest in 711 CE, North African influences were present long before the establishment of Al-Andalus. This region became a melting pot of cultures, languages, and religions.

Genetic Analysis of Ancient Individuals

The study involved DNA analysis from 12 individuals across three burial sites in Valencia. These samples spanned over a millennium, covering pre-Islamic, Islamic, and post-Reconquista periods. The findings revealed North African genetic markers in all samples, indicating a longstanding connection between the Iberian Peninsula and North Africa.

The Role of the Islamic Conquest

The Islamic conquest intensified the cultural and genetic intermingling between North Africa and Iberia. The researchers noted that the presence of Romance languages in North Africa facilitated this rapid conquest. The genetic data showed that this relationship was not a one-time event but had existed long before 711 CE.

The Impact of the Reconquista

The Reconquista, culminating in 1492, marked shift in Iberian demographics. Post-conquest, many Muslims, known as Mudéjars, faced forced conversions and persecution. The conversion process led to the emergence of the Moriscos, who maintained their customs in secrecy.

The Expulsion of the Moriscos

In 1609, King Philip III ordered the expulsion of the Moriscos from Spain. This decree resulted in the removal of portion of the population in the Kingdom of Valencia, estimated at over 300,000 individuals. This event effectively severed the genetic link to North Africa, as the expelled Moriscos were replaced by settlers from northern Spain.

Lasting Cultural Influences

Despite the expulsion, the cultural legacy of North Africa persisted in Iberia. The study indicates that some North African ancestry continued to exist until the 17th century. Additionally, this genetic heritage was carried by Iberian migrants to the New World during colonisation.

Conclusion of the Study

The research puts stress on the importance of understanding historical genetic connections. The genetic bridge between Europe and Africa, which had existed for centuries, was dismantled following the expulsion of the Moriscos. This loss marks the complex interplay of culture, identity, and genetics in shaping modern Iberian society.

Guillain-Barré Syndrome Cases in Andhra Pradesh

Image
  Recently, the state of Andhra Pradesh has witnessed a rise in Guillain-Barré Syndrome (GBS) cases, prompting government action. The Chief Minister has ordered an investigation into the outbreak. Earlier this year, Maharashtra also reported rising cases of GBS. About Guillain-Barré Syndrome Guillain-Barré Syndrome (GBS) is a rare autoimmune disorder affecting the peripheral nervous system. GBS is characterised by muscle weakness and paralysis. It typically starts with weakness, tingling, or numbness in the limbs. Symptoms can progress rapidly, leading to paralysis that may last from six months to a year. The syndrome affects nerves responsible for muscle movement and sensation. While it can occur at any age, it is more common in adult males. Causes and Triggers The exact cause of GBS remains unknown. However, it often follows infections, either bacterial or viral. The immune system mistakenly attacks the body’s nerves after such infections. Some rare cases have been linked to va...

Bharat Cancer Genome Atlas

Image
  The Indian Institute of Technology Madras recently launched the Bharat Cancer Genome Atlas (BCGA). This initiative aims to enhance cancer research in India. It addresses the under-representation of Indian genetic data in global cancer studies. The launch comes ahead of World Cancer Day and marks the increasing cancer incidence in the country. Overview of the Bharat Cancer Genome Atlas The BCGA is a comprehensive database of genetic variants linked to breast cancer in India. It collects data from breast cancer patients across the country. The goal is to identify specific biomarkers for early detection and develop targeted treatment strategies. Significance of the Initiative This initiative is crucial for understanding the unique genetic landscape of Indian cancers. The database will aid in the identification of cancer-specific biomarkers. It will also facilitate the development of diagnostic kits and targeted therapies tailored to the Indian population. Research and Collaboration...

New Study Reveals Dire State of Global Fish Stocks

Image
  A recent study published in the journal Science has found that global fish populations are facing more serious problems than we previously thought, with more fish stocks being overfished or in danger of collapse. Key Findings The study shows that current fishing practices are taking more fish than can naturally be replenished, mainly due to both local and large-scale industrial fishing. Researchers looked at data from 230 different fish stocks and discovered that past reports had overestimated how many fish were available and how quickly they could recover. Issues with Catch Limits Policymakers set limits on how many fish can be caught based on scientific advice to prevent overfishing. However, these limits have often been set too high, which has resulted in nearly one-third of fish stocks labeled as “sustainably fished” by the FAO actually being overfished. What is “Phantom Recoveries”? The study also found cases of “phantom recoveries,” where fish populations appeared to be doi...
