How Ecotypes Harbor the Genetic Memory of a Species’ Past
Evolutionary biologists are exploring how ecotypes enable species to adapt to specific habitats without becoming separate species. Research into the genetic mechanisms behind these adaptations reveals that distinct traits can arise within a single species. This understanding challenges traditional views of speciation and highlights the role of genomic diversity in evolution.
- ▪Ecotypes are subpopulations of a species adapted to specific local environments.
- ▪Recent genomic studies show that multiple distinct traits can exist within a single species without leading to speciation.
- ▪The concept of ecotypes was first introduced by botanist Göte Turesson in 1922, but it wasn't until the early 2000s that it could be scientifically tested.
