What animals can reproduce without a mate
Greenflies, stick insects, aphids, water fleas, scorpions, termites and honey bees are all capable of reproducing without males, using parthenogenesis..
Which is an example of asexual reproduction by regeneration
Regeneration is a type of asexual reproduction in which the organism is capable of regrowing certain body parts. Regeneration occurs via mitosis. Lizards can regenerate their tails, star fish can regenerate their arms while humans have the ability to regenerate their liver to a certain extent.
Why do humans not reproduce asexually
Why can’t humans just reproduce asexually? Short answer? Because we humans didn’t evolve that way. Most organisms that reproduce asexually are single-celled and reproduce by binary fission, but these are not nowadays classified as animals, much less vertebrates, much less mammals, much less human.
When did humans realize where babies come from
Until 1875, no one in the world knew where babies come from. Ordinary people didn’t know, and neither did the scientists who helped shape the modern world. Leonardo da Vinci didn’t know.

What will happen if all organisms reproduce asexually
Asexual reproduction If the organisms of a species all fail to reproduce then the species may become extinct. Asexual reproduction does not involve sex cells or fertilisation . Only one parent is required, unlike sexual reproduction which needs two parents.
What is the downside of asexual reproduction
Offspring are genetic clones. Asexual reproduction can cause negative mutations, which make asexually produced organisms are susceptible to diseases. This also means a large number of offspring would be destroyed.
What happens if a human and an animal mate
Humans are animals too. … If a human mates with another species it is very unlikely that there would be any offspring: the egg and sperm would most likely not join together. And even if they did the offspring would probably be infertile. It’s also illegal.
Why do humans not have mating seasons

What animal can impregnate itself
Other creatures also engage in ‘selfing’ — many plants pollinate themselves, and animals including the New Mexico whiptail, a lizard, can impregnate themselves too.
Are worms asexual
Earthworms can also reproduce themselves if need be. They can regenerate new segments if they lose a few. … They don’t reproduce asexually, however; only half (and likely the head half) of an earthworm split in two will regenerate into a full worm once again [source: Tomlin].
