Why The Best Children Are Born To Parents Who Are In The Prime Of Their Lives
Scientists have created the first mathematical model to describe how an individual’s age and experience affect investment in their progeny, which was inspired by the tsetse fly.
In many mammals, birds, and insects, the allocation to offspring follows an increase-decrease pattern. Researchers from Bristol discovered this pattern in the tsetse fly, a significant disease-carrying insect. They worked with colleagues from Exeter and Oxford. Live young that are about the same size as their mother are born when tsetse flies bite.
The researchers spent their entire lives in the lab observing tsetse mothers with colleagues from the Liverpool School of Tropical Medicine. In order to demonstrate how the pattern may be explained by changes mothers undergo as they age, the team has now developed a mathematical model, which was published in the journal Proceedings of the Royal Society B.
Blood is a valuable food source that tsetse find difficult to obtain. To find an animal and get past its defenses, such as a swatting tail, the insects must travel a great distance in the air. Tsetse is undoubtedly better at finding food with practice, but as their wings deteriorate, they require more energy to fly. When passing on fat to their kids, tsetse moms have evolved to react to these impacts.
All animals that bear more than one child during the course of their lifetimes are included in the mathematical model.
According to their ecological context, it forecasts the strategic decisions that people will make. Some species will devote almost all of their resources to each breeding event, whereas others will accumulate resources and reproduce less frequently. One goal of the initiative is to explain this diversity.
The group is creating a model that will take the parasites that tsetse transmit into account. It is hoped that a deeper comprehension of these significant insects would help stop the spread of diseases like sleeping sickness to people and livestock.
