By: Erich Blechschmidt M.D., R.F. Gasser Ph.D.Fifty years ago the field of human embryology was incomplete; prior to that time the anatomy of early human embryos was still unknown, and there was much to be learned about the older stages of human embryonic development. It is now understood that human organs result from step-by-step differentiations of the growing human embryo. Research by renowned embryologist Erich Blechschmidt, MD, showed that differentiations are not only the result of a gene effect, but are also brought about through growth initiated by extragenetic (occurring outside the gene) information. Without this extragenetic information the differentiation would not begin.
Dr. Blechschmidt and coauthor Raymond Gasser, PhD, maintain that Haeckel's biogenetic law (ontogeny recapitulates phylogeny) was an erroneous attempt to explain developmental processes. Blechschmidt's human embryological investigations showed that Darwin's principles (mutation and selection) are likely valid for the origin of the species, but that they cannot explain the ontogenesis of the organs. The ontogenesis of each individual cannot be derived from phylogenetic facts. The authors stress that a clear distinction must be made between the vast field of phylogenetics and the much more exact and understandable field of ontogenetics—particularly the process of differentiation—and their goal is to present not only the abstract biokinetic principles of differentiation, but the originality of embryonic human beings as well. Their knowledge of developmental movements leads to their conclusion that differentiation is an undivided biodynamic process that occurs during development and includes the chemical processes as well.
Logically organized into two sections (the first covers early metabolic fields and includes chapters on the one-cell human ovum, the early embryo, blood vessels, the nervous system, head region, trunk, and limbs; the second describes metabolic fields in later developmental stages, distinguishing fields of corrosion, densation, contusion, distusion, retention, dilation, liquation, and detraction), Biokinetics and Biodynamics of Human Differentiation warrants reading by thoughtful professionals in a number of fields concerned with embryonic differentiation. A new preface by Dr. Gasser addresses how the book's principles and findings were and are understood in the field of human embryology.

Was so hopeful!
Style: Lobster, Size: One Size, Style: Lobster, Size: One Size
My dog Dax is like a big German Shepherd trapped in a little Chawinnie. he’s only one and loves to chew on stuffed toys like this. I was excited to try this brand out because it looked very promising. Unfortunately only lasted a little over 48 hours and he was able to gutt it out & rip off the eyes. He really loved it though, it has a different sounding squeaker and when he bit it the tail would flop up/down, I also like that the squeaker part was right in the middle which made it hard for him to get to it since his mouth is small.. despite that he was still able too. The size was perfect for him though so I’ll probably sew it up and give ir back to him then order another one. Giving 4 stars because it’s well made can’t help that my dogs ferocious!

My fur baby loves this toy.
Style: Lobster, Size: One Size
This toy works for my fur baby because she is a small Shih Tzu and not a rough chewer. It has lasted and has proved durable for her but may not be appropriate for an aggressive chewer or for a large fur baby. Because it is made of soft cloth I would not recommend for teething. Otherwise, I found this toy to be reasonably priced and one my fur baby loves to play with.

GoDog is usually tough; not this one
Godog is usually my go-to for soft toys that will last. My staffy/bully is a toy surgeon who like most pitties can shred a “ indestructible” toy in seconds. I have found a few that last him a long time: West Paw rumpus, some Fluff n Tuffs, some GoDog and the Benebone maple stick (although be careful with the latter, my boy broke a tooth on one 🤦♀️). He does eventually destroy some of those but more like six months to a year not minutes. He has a collection of GoDog dragons / dinosaurs that have lasted him like a year! They get ragged and sometimes one day he decides to really take it apart, but mostly they’re so big and have so many floppy parts that he just runs around proudly with them or sleeps with them or choose them gently for hours. This one wasn’t like any of the other godog toys we have. Maybe there’s a reason it was half off…Not tough at all. A toy has to last at least five minutes. It didn’t even last five minutes and the ears were off and the squeaker was out. Not well made. I do generally like the brand though.
