In the mid term future it may well become possible with advanced technology for a human woman to become a surrogate mother for any type of mammal - in theory, either by the use of a modified placenta which could support an embryo from another species, or by altering the way the mother's immune system works. There are many endangered species of mammal where the babies are not too large for a human womb to carry - gorillas and pandas are examples (the babies have about half the average birth weight of human babies).
Would you consider becoming a surrogate mother for an infant member of an endangered species, or would you rule it out for health and safety/religious/other reasons?
What Girls Said
My sister sure would
I suppose a follow up question would be to ask her whether she would volunteer for something that would require more advanced technology - like being the surrogate mother of a small dolphin. The smallest type of baby dolphin weighs as little as 8 kg, which is heavier than a human baby, but it's not beyond the limits of technology.
Sound alike a movie or furry
Dunno about a full length movie, but Ai Hasegawa made a very short video in which a model appears to give birth to a baby dolphin (it's actually just an animatronic). The technology will most likely be possible in the mid-term future, but the question is whether it would be less difficult and costly than growing baby animals in a machine in a lab.
