As the old proverb says, “Do not let bed bug bite.”
But according to a new study, insects have been eliminating humans since their appearance of caves about 60,000 years ago, making them possibly “the first real urban lesion.”
Researchers said in the population that the evidence for our symbiotic relationship with parasites that absorb blood can now inform the prediction models to spread pests and diseases with the explosion of cities in the population. Ticket It was published on Wednesday in Biology Letters.
Through genetic analysis, researchers from Virginia Tech found that the population of both bed bugs related to the beater and those that jumped to humans continued to decline until the last ice age, about 20 thousand years ago.
This is the place where the noiles begin to spoil.
“The truly exciting part is that the proportions associated with human beings press release Wednesday.
About 12,000 years ago, when humans began building large settlements that expanded into cities such as Mesopotamia, the number of bed bugs increased as well, adding that creatures, which live in furniture and nourish blood, precede mice and cockroaches such as local pests.
The study said that the types of bedding bats fell.
The researchers added that the study of demographic patterns provides “convincing evidence that the proportions associated with humans follow the demographic history of modern humans and their movement in the first cities.”
“There was bed bugs living in the caves with these people, and when they went out, they took a sub -group of the population with them, so there is a less genetic diversity in those percentages associated with humans,” said Warren Booth, associate professor of urban insectology in Virginia Tech, who also studied the study.
Miles said the team wanted to look at how the “effective population size”, or the number of individuals who contribute to the next generation, over time, “because this could tell you what is happening in their past.”
The first human civilizations appeared about 10,000 years ago and provided ideal conditions for the “spread of contradictory urban pests”, and Miles and Both wrote in their results, adding that this raises questions about whether contradictory relationships between humans and other pests also appeared earlier.
