The notion of resurrecting extinct species has long captured the human imagination, reminiscent of science fiction tales such as "Jurassic Park." Yet, with advancements in genetic engineering and a deeper understanding of DNA, this once fantastical idea is inching closer to reality. De-extinction, the process of reviving extinct species through genetic technologies, holds promise for conservation but also raises ethical and ecological considerations. This concept could potentially restore ecosystems and correct historical ecological imbalances. Below, we explore 15 extinct animals that scientists are considering for revival.
