Cloning has been used by scientists since the 1950s. [5] One of the most well known clones is Dolly the sheep. Dolly was born in the mid 1990s and lived normally until the abrupt midlife onset of health complications resembling premature aging, that led to her death. [5] Other known cloned animal species include domestic cats, dogs, pigs, and ...
The coexistence of avian dinosaurs (birds) and humans is well established historically and in modern times. The coexistence of non-avian dinosaurs and humans exists only as a recurring motif in speculative fiction, because in the real world non-avian dinosaurs have at no point coexisted with humans. [1]

The ban excluded cloning for research, and for the conservation of rare breeds and endangered species.
Scientists have cloned the first rhesus monkey, a breakthrough that could help advance medical research but has drawn criticism from an animal welfare group. New cloned monkey species highlights ...
High fetal and neonatal death make the process very inefficient. Resulting cloned offspring are also plagued with development and imprinting disorders in non-human species. For these reasons, along with moral and ethical objections, reproductive cloning in humans is proscribed in more than 30 countries. [31] Most researchers believe that in the ...
The world’s first cloned black-footed ferret has given birth in a historic first for conservationists. Antonia the ferret successfully delivered two healthy kits after mating with Urchin, a ...
