Product Details

Reproduction is the mainspring of life. It's one of the two main activities that characterize the livings; to get the food to survive and to reproduce, in order to propagate the species. Here is a series of slides that, starting with the simplest to the most complex invertebrates, will show you a panorama on the ways of reproduction of animals. Amphioxus, inserted into this series, is not properly an invertebrate, but represents the simplest animal with a "dorsal corda", the organ that will become the vertebral column of vertebrates. What an amazing set of slides!

You get 15 prepared slides and 5 blank ones that come in a sturdy and cool looking wooden case. Plus, it's in 8 languages; English, Italian, French, German, Russian, Spanish, Portuguese, and Greek!
