Summary
Malaria, caused by Plasmodium falciparum, significantly influenced early human migration and habitat choices in Africa. Humans actively avoided areas with high malaria transmission risk, showing disease as a key factor in population distribution.
Area of Science:
- Paleoanthropology
- Epidemiology
- Climate Science
Background:
- Climate is traditionally viewed as the primary influence on early human spatial organization in Africa.
- Emerging evidence from genetic and archaeological studies indicates diseases were significant selective pressures during the Pleistocene epoch.
Purpose of the Study:
- To investigate the role of Plasmodium falciparum-induced malaria in shaping human habitat selection in Africa between 74,000 and 5,000 years ago.
- To determine if malaria risk influenced early human societal distribution and demographic patterns.
Main Methods:
- Utilized species distribution models for mosquito complexes.
- Integrated palaeoclimatic data and historical epidemiological information.
- Developed a time-series index of malaria transmission risk across sub-Saharan Africa.
Main Results:
- Reconstructed the human niche independently.
- Correlated malaria transmission risk with human habitat distribution.
- Identified significant avoidance of high-risk malaria zones by human populations.
Conclusions:
- Malaria transmission risk was a critical factor in early human spatial organization and habitat choice.
- Disease distribution, alongside climate, played a crucial role in shaping past human demography, population structure, and dispersal patterns.
- Future models of human evolution must incorporate disease dynamics.

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

2.9K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.

Protists are diverse eukaryotic microorganisms that lack the specialized tissues of plants and animals and the chitinous cell walls of fungi. Their early divergence within Eukarya resulted in structural, functional, and ecological diversity. They are classified into supergroups such as Archaeplastida, Excavata, Amoebozoa, Rhizaria, Alveolata, and Stramenopiles, determined through genetic analysis and structural similarities.Structural and Functional AdaptationsProtists have various adaptations...

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...
