Colossal Biosciences announced that Romulus and Remus, two male dire wolves born through the company’s groundbreaking genetic engineering program, have reached their first birthday. The Dallas-based biotech revealed in April 2025 that two litters of dire wolves had been born—Romulus and Remus in October 2024, followed by a female, Khaleesi, in January 2025. The milestone marks another step forward in Colossal’s efforts to advance de-extinction and conservation science.
