🧬🐟 The #Amazon #molly, an all-female #fish from #Texas and #Mexico rivers, has cloned itself for over 100,000 years – long past the predicted extinction deadline.
A 2026 #Nature #study by researchers at University of #Missouri and LMU #Munich shows the fish uses “gene conversion,” a #DNA repair trick, to erase bad #mutations and spread good ones without #sex.

Hands up if you believe in virgin birth. Nobody? Well... an iguana in a UK zoo has given birth to eight tiny hatchlings, despite never having met a male iguana.
"It's a miracle!"
Nope, it's called 'parthenogenesis' where an embryo develops directly from an egg without being fertilised. The babies are all perfect clones of their mum. Many species have this ability, mainly lizards.
There's a delightful comment from the zoo's owner: "They all speak at exactly the same time."
Bless their tiny green souls.
Next week: "Was Jesus an Iguana?"

#DidYouKnow: #Parthenogenesis (#Virgin #Birth) is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing).
Parthenogenesis occurs naturally in some plants, algae, invertebrate animal species.

In most organisms eggs are produced by splitting the number of chromosomes (carrying the genetic material of the DNA) that occur in most cells in an animal’s body, to half the normal number. Only after fertilization by sperm (also with the split half number of chromosomes) is the full complement restored. In #parthenogenesis, no reduction splitting occurs, all eggs are full-chromosome clones of the mother, and all will also be female. -

Sex as a formality: Male stick #insects have lost their reproductive function
https://phys.org/news/2025-02-sex-formality-male-insects-lost.htmlLack of successful sexual reproduction suggests the irreversible #parthenogenesis in a stick insect https://esajournals.onlinelibrary.wiley.com/doi/10.1002/ecy.4522
"While most #animals reproduce sexually, some species rely solely on females for parthenogenetic reproduction. Even in these, rare males occasionally appear. Whether they retain reproductive functions is a key question in the #evolution of reproductive strategies."

Recent updates in #parthenogenesis: in a Japanese species of stick insect that relies on parthenogenesis for reproduction, the rare males mated with females but pointlessly. The males are sterile and none of their genes are passed along. "Surprisingly, the rare males of this stick insect have completely lost their reproductive function," remarked Dr. Kaneko.
