Having children means finding a suitable partner first, but finding this can take a very long time. Few animals have been able to completely abandon the long search process of finding a “suitable partner”. Because its reproduction is asexual, and it clones itself.

The marble crab is a parthenogenetic crab and an example of an animal that clones itself. According to recently concluded studies by German researchers, all of these types of cancer are female and are cloning themselves.

Until now, it was not fully understood how the marble crab lost its sexual reproduction. But genetic analyzes show that it is a descendant of a species of lobster found in North America. Scientists believe that a mutation occurred in one of the crabs in the 1990s, causing its reproduction to become asexual.

What distinguishes asexual reproduction is that one female is enough to reproduce an entire species. The “virgin gecko” is one of the animals that relies on self-cloning for its reproduction. They live on completely isolated islands in the Pacific Ocean.

Binary rotifers are microscopic aquatic animals. About 40 million years ago, these animals reproduced asexually. It is true that the environmental conditions on earth have undergone many changes. However, this type of animal survives probably because it has genes from other organisms such as bacteria or fungi in its DNA.

Marble crabs, dioecious rotifers, etc. are all sexually reproducing animals. But there are animals that teach sexual reproduction. The rainbow lizard is an example of these animals. This lizard lives in Central and South America. Some members of the species reproduce asexually, while others reproduce asexually.

Asexual reproduction rates decrease in animals that live in groups. But at London Zoo, a virgin Commodore dragon gave birth to four cubs in 2006. It is clearly not a clone. Rather, it is reproduction without male fertilization. Newborn babies have the same genetic material as their mothers.

Even sharks have cases of asexual reproduction. In 2007, a shark in the US gave birth to a male infertile baby. Notably, there are cases of self-cloning in the bamboo shark and zebra shark species.

Until now, scientists had not observed the birth of mammals through self-cloning. Scientists believe this is due to the complexity of the mechanisms behind embryo formation in mammals. Which is an advantage. Through sexual reproduction, the risk of harmful mutations is reduced.
