Who discovered cellular totipotency?
Totipotency was first discovered by German scientist Hans Spemann in the early 20th century. Spemann demonstrated that individual cells from early embryos of salamanders were capable of developing into complete organisms when transplanted into other embryos. This discovery laid the foundation for our understanding of cellular totipotency in embryonic development.
How did spemann separate the two cells of the embryo of a salamander in 1902?
In 1902, Hans Spemann separated the two cells of a salamander embryo using a fine hair loop to physically divide the two cells shortly after the first cleavage. This technique allowed him to observe the developmental potential of each cell. Spemann's experiment demonstrated that each cell could develop into a complete organism, supporting the concept of developmental equivalence in early embryonic cells. This work laid the foundation for future studies in developmental biology and embryology.
Who first came up with the idea for cloning?
The concept of cloning was first proposed by German biologist Hans Spemann in the early 20th century. He hypothesized that it might be possible to create identical copies of organisms through a process known as "nuclear transfer."
