Hans SpemannBorn 27 Jun 1869; died 12 Sep 1941 at age 72.German embryologist who was awarded the Nobel Prize for Physiology and Medicine (1935) for his discovery of embryonic induction, an effect involving several parts of the embryo in directing the development of the early group of cells into specific tissues and organs. Working extensively on the early development of the newt, he showed that the in the earliest stage, tissues may be transplanted to different areas of the embryo, and it then develops based on the new location and not from where it came. For example, early tissue cut from an area of nervous tissue might be moved to an area of skin tissue where it then grows into the same form as the surrounding skin.
When can we see the baby?
With all the new technology regarding fertility, an 88-year-old woman was able to give birth to a baby recently.
When she was discharged from the hospital and went home, various relatives came to visit. May we see the new baby? one of them asked.
Not yet, said the mother. I'll make coffee and we can visit for a while first.
Another half hour passed before another relative asked, May we see the new baby now?
No, not yet, said the mother.
A while later and again the guests asked, May we see the baby now?
No, not yet, replied the mother.
Growing impatient, they asked, Well, when can we see the baby?
When it cries! she told them.
"When it cries? they gasped. Why do we have to wait until it cries?
Because, I forgot where I put it.
