[Animals] Is evolution a repetitive process or a product of chance?

[Noticias ALEJANDRO]

Some theories maintain that the evolution of species is a random process, which acts on a multiplicity of traits that appear randomly through genetic variation. However, a new insect-based study partly casts doubt on that notion, arguing that evolution can sometimes repeat itself in predictable ways. This could help understand how organisms can change in response to selection and adaptation pressures.

 

 

A new international study recently published in the journal Science Advances, which included the participation of scientists from Utah State University and the University of Nevada in Reno, in the United States, the University of Montpelier and the University of Notre Dame, in France , and the Federal University of São Paulo, in Brazil, provide new findings on repeated evolution: recurring evolutionary changes over time in stick insects would indicate that evolution, at least in part, could be a repetitive process and not only random
