All-Female Species Exist, but All-Male Species Do Not

 All-female species are quite common in nature. Many lizards, sharks, snakes, and insects reproduce via parthenogenesis (''virgin birth''), entirely eliminating males.

Nature is packed with highly complex, all-female animal species that are completely healthy, incredibly diverse. Some species are tens of millions of years old - the Bdelloid rotifers, which have survived and diversified without a single male for over 60 to 80 million years. The oldest all-female animal lineages are the Darwinulid ostracods, which have survived and diversified without a single functional male for over 200 million years Instead of suffering from genetic decay or systemic sickness, these species frequently possess superior immune systems, higher tolerance for environmental stressors, and highly efficient DNA repair mechanisms that rival or exceed those of sexual species.All-female species are not fragile anomalies, but highly successful, biologically resilient evolutionary powerhouses.

Females possess the complete biological toolkit: They have the genetic material, the eggs, and the physical anatomy to reproduce, allow embryos to develop, and sustain a 100% independent species by themselves.

Males do not: A male cannot produce an egg, cannot provide cellular nutrients for an embryo, and cannot give birth.

Therefore, the statement "All-Female Species Exist, but All-Male Species Do Not" is indisputably 100% true. There is no loophole or exception that changes that fundamental biological reality. An independent all-male species is biologically impossible.

Species composed entirely of females exist across several animal classes and reproduce through obligate parthenogenesis, a form of asexual reproduction where unfertilized eggs develop into viable female offspring. These species have effectively eliminated males from their populations, resulting in all-female genetic lines.

REPTILES & AMPHIBIANS - New Mexico Whiptail Lizard (Aspidoscelis neomexicana) - Desert Grassland Whiptail Lizard (Aspidoscelis uniparens) - Laredo Striped Whiptail Lizard (Aspidoscelis laredoensis) - Sonoran Spotted Whiptail Lizard (Aspidoscelis sonorae) - Mourning Gecko (Lepidodactylus lugubris) - Indo-Pacific Gecko (Hemidactylus garnotii) - Brahminy Blindsnake (Indotyphlops braminus) - Caucasian Rock Lizard (Darevskia armeniaca) - Dahli's Lizard (Darevskia dahli) - Rostombekov's Lizard (Darevskia rostombekovi)

 FISH & CRUSTACEANS - Amazon Molly (Poecilia formosa) *Requires gynogenesis/sperm contact, but populations are 100% female - Marbled Crayfish / Marmorkrebs (Procambarus virginalis) - Texas Silverside Fish hybrid lineages (Menidia clarkhubbsi)

 

Facultative parthenogenesis is the biological ability of a sexually reproducing species to switch to asexual reproduction under specific conditions. Unlike obligate parthenogenesis, these species have regular male and female populations, but females can produce viable offspring from unfertilized eggs if mates are unavailable. 

Apex predators like the Komodo dragon, various sharks, and the California condor are facultative

 

If Y created everything-- according to humans -- then why is Y degenerating at a constant rate? Why did Y diverge from X and not the other way around (which would be the case if Y = creator). Why is Y a degenerate copy of X? Rhetorical questions.

Y is going extinct :)))))

The Meat Grinder (Governess of CN) will get her wish come true :))))) 

Right, in other words, any tigress in the mood for a hunting party?
