Your Inner FishI empathize with those descriptions, which illustrate the serendipitous nature of finding fossils and also the predictability that is possible when researchers have done their homework. Shubin describes the magic of anatomical dissection and the fundamental homologies among limbs of different vertebrates. Shubin and colleagues have contributed much to our understanding of the origin of vertebrate limbs with digits. This fish, with fins possessing basic wrist-like joints that could support the front of the body out of water, is believed to be a transitional animal whose existence partly bridges the gaps in our understanding of the emergence of tetrapods four-legged animals from their fish ancestors. Subsequent chapters focus on the history of discoveries of the embryonic origins and genetic control mechanisms at work in different regions of the body. This historical background brings home to the reader that science is performed by people in the context of their times. More deeply, he reveals the connections between humans and multicellular organisms at the cellular and molecular levels and the relationship of those connections to features prefigured in unicellular organisms.
Dr. Neil Shubin: Finding Your Inner Fish
How can a walk through the zoo help us predict where we should look in the rocks to find important fossils? A zoo offers a great variety of creatures that are all distinct in many ways. But let's not focus on what makes them distinct; to pull off our prediction, we need to focus on what different creatures share. We can then use the features common to all species to identify groups of creatures with similar traits. Unlock explanations and citation info for this and every other Your Inner Fish quote. It took us six years to find it, but this fossil confirmed a prediction of paleontology: not only was the new fish an intermediate between two different kinds of animal, but we had found it also in the right time period in earth's history and in the right ancient environment.
Metrics details. All animals are the same but different. Like a cake recipe passed down from generation to generation—with enhancements to the cake in each—the recipe that builds our bodies has been passed down and modified for eons.
