"Don parrots are among the smartest of all birds. They have highly expanded brains and complex vocal abilities and social structure in the lab. They appear to be as smart in some ways as monkeys and apes surprising because parents and other birds are very distant from monkeys apes and humans in their evolutionary ancestry. The four brain of part of the brain involved in intelligence is structured differently in birds than in humans and other mammals. Parents must have volved their intelligence along a separate evolutionary path from the one taken by humans and their close relatives, the apes and monkeys. Yes. But when scientists studied parrot genes involved in brain development, they were surprised to find some unexpected similarities with humans in two thousand eighteen a team of American and Brazilian researchers analyzed the genome of the blue fronted. Amazon a parrot found in Brazil and compared its jeans with thirty other bird species. They found that regions of the parrot genome that regulate when and how genes for brain development are turned on are different from many other birds. These regions appear to have separately undergone some of the same changes as those found in the human genome through Saugus example of Lucien there. Biologists called convergent. Evolution similar genetic changes happened separately in two different groups of animals because their environment favor the same kinds of traits. That's right. It's interesting that some of the genes involved are also implicated in human disabilities such as autism developmental disabilities. And schizophrenia studying the evolution of genes. And brains might help researchers to better understand and prevent these disabilities. There's moment of science comes from Indiana University. I'm Don glass, and I'm Yale Cassandra."
