Dire Wolves Grow Up at Colossal Biosciences, Snacking on Deer Marks Maturation

Colossal Biosciences has brought dire wolves Romulus and Remus to life from ancient DNA, raised with surrogate dog mothers, and they are now about 16 months old with maturation to around age three. They recently fed on their first deer carcass and also catch small prey on Colossal’s 2,000+ acre preserve, illustrating their wolf nature rather than domestication. A female pup named Khaleesi, born Jan. 2025, rounds out the trio. They’re friendly toward staff when fed but remain wild wolves, not pets.

Colossal's Genetically Engineered Animals: Reality or Fiction?

Colossal Biosciences, led by Ben Lamm, claims to have made progress in de-extincting species like the dire wolf and woolly mammoth through genetic engineering, but scientists remain skeptical, arguing that these are not true resurrected species but genetically edited animals that do not fully replicate the original extinct species. Critics warn that overhyping such claims can undermine scientific trust and emphasize that traditional conservation efforts remain essential.

Neanderthal Revival: Scientific Breakthrough or Ethical Dilemma?

Scientists believe it may be possible to bring back Neanderthals within 20 years using advanced genetic engineering, but this raises significant ethical, scientific, and legal concerns, including the potential for unregulated private ventures and the moral implications of creating a new human-like species.

Scientists and startups make breakthrough in dodo de-extinction efforts

Colossal Biosciences has made a significant breakthrough in their effort to genetically engineer a dodo-like bird by successfully culturing primordial germ cells from pigeons, a key step towards potentially recreating the extinct species, though experts caution that true de-extinction remains scientifically complex and controversial.
