We are working in the lab to understand this moment in development, which is called phenotypic. This is something that has been known for over a hundred years. When you see many vertebrate embryos at this early embryonic time point, all embryos look very, very similar. We are extrapolating these ideas to the brain. We have seen that at this time point, the phenotypic period, all brains of these species are very simple but very closely related. We share the same features with a fish or with a gecko or with any other mammalian species at this early time point. We have the same brain with the same genes active and the same cell types involved in it.

Dr. Fernando García-Moreno is a neuroscientist whose work explores the deep evolutionary roots of the brain—and what they reveal about identity, complexity, and even the future of technology. From the thalamus to the phylotypic brain, his research uncovers how our most fundamental brain structures co-evolve—and how they shape, and limit, the way we think. As we navigate an age shaped by AI and rapid innovation, Fernando brings a powerful lens: one that reminds us where we come from—and what evolution may still be writing into our futures. He is an Ikerbasque Research Associate at the Achucarro Basque Centre for Neuroscience.
