Is this gravely wrong?

Hello! My friend brought to my attention efforts to make “Embryos That Are Both Animal And Human” The following is from an NPR article on the subject -
“A handful of scientists around the United States are trying to do something that some people find disturbing: make embryos that are part human, part animal.
The researchers hope these embryos, known as chimeras, could eventually help save the lives of people with a wide range of diseases…
But some scientists and bioethicists worry the creation of these interspecies embryos crosses the line. “You’re getting into unsettling ground that I think is damaging to our sense of humanity,” says Stuart Newman, a professor of cell biology and anatomy at the New York Medical College…
“If you have pigs with partly human brains you would have animals that might actually have consciousness like a human,” Newman says. “It might have human-type needs. We don’t really know.”
That possibility raises new questions about the morality of using the animals for experimentation. Another concern is that the stem cells could form human sperm and human eggs in the chimeras.
“If a male chimeric pig mated with a female chimeric pig, the result could be a human fetus developing in the uterus of that female chimera,” Newman says. Another possibility is the animals could give birth to some kind of part-human, part-pig creature.”"
In light of the Truths of the Faith, how should we look at this? Thank you, and may God bless you! :slight_smile:

Attempts at hybridization

  1. Recently animal oocytes have been used for reprogramming the nuclei of human somatic cells – this is generally called hybrid cloning – in order to extract embryonic stem cells from the resulting embryos without having to use human oocytes.

**From the ethical standpoint, such procedures represent an offense against the dignity of human beings on account of the admixture of human and animal genetic elements capable of disrupting the specific identity of man. **The possible use of the stem cells, taken from these embryos, may also involve additional health risks, as yet unknown, due to the presence of animal genetic material in their cytoplasm. To consciously expose a human being to such risks is morally and ethically unacceptable.
