A new study finds that machine learning models can identify behavioural cues in zebrafish to correctly predict when the fish is anxious.
Researchers at IIT Bombay discover the role of environmental resources, genes and mating in species in the development of new species in the same area, challenging the traditional view that new species can develop only in distinct geographies.
Why do we see certain species of animals in one place while they are absent in the neighbouring regions? How do species inhabit remote islands? Questions like these are central to our understanding of evolution and speciation. Exploring these question in a Sri Lankan context, scientists from National Centre for Biological sciences and University of Colombo studied how a two species of small passerine birds colonized the island nation. Through phenotypic and genotypic analysis they could show that not all Sri Lankan wildlife is a subset of Indian wildlife.
