I was troubled that the retrieval of organs from executed prisoners was at least as morally controversial as the harvesting of stem cells from human embryos.
If this research is successful, it may then reduce the need to research and sacrifice human embryos.
And I have been fortunate enough to find things like the first eggs in the Western hemisphere and the first baby dinosaurs in nests, the first dinosaur embryos and massive accumulations of bones.
I shared my nursery with other embryos and juveniles, from clams and crabs to sea urchins and anemones.
And pretty soon, we had early-stage embryos with hundreds of cells forming those.
Chinese scientists showed recently that they could even use the CRISPR technology to change genes in human embryos.
The opportunity to do this kind of genome editing also raises various ethical issues that we have to consider, because this technology can be employed not only in adult cells, but also in the embryos of organisms, including our own species.
This raises a number of ethical questions that we have to carefully consider, and this is why I and my colleagues have called for a global pause in any clinical application of the CRISPR technology in human embryos, to give us time to really consider all of the various implications of doing so.
And this is true all around the world; scientists are figuring out new ways to handle their embryos, to get them to settle, maybe even figuring out the methods to preserve them at low temperatures, so that we can preserve their genetic diversity and work with them more often.
Embryonic stem cells are created from leftover embryos that are willingly donated by patients from fertility clinics.
Most mammal mothers can expel or reabsorb embryos if required, but in humans, once the fetus is connected to the blood supply, severing that connection can result in hemorrhage.
So it makes sense that the body should screen embryos carefully to find out which ones are worth the challenge.

Researchers in China just a few months ago reported the creation of genetically modified human embryos.
After fertilization, embryos can be further screened for genetic suitability, frozen for later attempted pregnancies, or delivered into the woman's uterus via catheter.
To increase the odds of success, which are as high as 40% for a woman younger than 35, doctors sometimes transfer multiple embryos at once, which is why IVF results in twins and triplets more often than natural pregnancies.
Like other embryos, turtle embryos are made of undifferentiated cells that become specific cell types, and then organs and tissues, through gene activity and communication between cells.
At first, turtle embryos look very similar to those of other reptiles, birds, and mammals, except for a bulge of cells called the carapacial ridge.
This was the second dilemma: (MS) A company offers a service that takes a fertilized egg and produces millions of embryos with slight genetic variations.
Today, we know human embryos have tails that dissolve as the embryo develops.
You try to get the highest quality embryos.
And how do you get the highest quality embryos?
We sell them, we kill them as embryos, we enslave them, we rape them.
And you can do some pretty strange things because in the same way as you can reprogram this apple, if you go to Cliff Tabin's lab at the Harvard Medical School, he's reprogramming chicken embryos to grow more wings.
