| Summary: |
Looking at embryos without a microscope does not show much by
itself. Human embryos are too tiny to see at all other than as teensy
specks in a laboratory dish at a fertility clinic. Frog embryos are large
enough to see, but not with much detail: a big egg cell divides into
other cells and then gives rise to a tadpole, which swims around for a
while then metamorphoses through a pro cess of changing shape into
a frog. Chick embryos are inside eggshells. Other species form in similar
ways, and without a microscope to magnify the cells, we cannot
see much of the intricate detail that is there in any of them. |
