Why do snakes have pelvic bones?
Snakes have pelvic bones as remnants of their evolutionary history when their ancestors had hind limbs. These pelvic bones have been greatly reduced in size and are not functional for walking or supporting legs, but they still play a role in supporting reproductive organs.
Is the theory of evolution true or fake?
The theory is true. Darwin suggested it via Natural Selection. In other words, there is such a thing as the theory of evolution. The questioner presumably wants to know Is evolution possible? and Is there evidence for evolution? and How robust is evolution as a theory?There is evidence for evolution from great realms of science. The fossil record shows thousands of Pre-Holocene species (trilobites, coelurosaurs, condylarths and many other extraordinary creatures) and many transitions (Ichthostega, Ambulocetues and Australopithecus for example). Comparative genetics shows that birds and crocodiles are closely related and lizards and snakes are closely related, exactly as what should be hypothesised from a branching tree of evolving life. Biogeography explains why all marsupials exist only in South America and Australia (South America and Australia were joined as Gondwana before splitting apart into their present continents and separating the ancestors of oppossums and Australian marsupials forever), and Natural Selection explains why things look the way they do (polar bears would not survive in Arctica without a white, thick coat and marine mammals would not survive without flippers) and comparative anatomy shows that all have a common ancestor (whales share a common ancestor with cats and bats and beavers and all mammals as seen by the identity of the bones in the limbs).One illustration for each of the realms of evidence is hardly good enough. Do research (anywhere, among animals and plants and bacteria and protists) and there should be abounding evidence for evolution everywhere.Evolution is not a fake. Yes, Piltdown Man was fake, but Australopithecus is not and nor are the many Homospecies in the fossil record. There are multitudinous and multifarious evidences (see above) for evolution. Darwin published On the Origin of Species in 1859. Once science woke up to it, I don't think it looked back since.
What would an anoligest study?
An anologist studies reptiles, including snakes, lizards, and turtles. They focus on their behavior, ecology, morphology, and evolution. This field also involves research on conservation and habitat management for these reptilian species.
What kind of snakes eat frogs?
Some snakes that eat frogs include garter snakes, water snakes, and ribbon snakes. These snakes are non-venomous and rely on their speed and agility to catch and consume frogs as part of their diet.
Snakes are members of Order?
Snakes are members of the Order Squamata, which also includes lizards. They are elongated, legless reptiles with flexible bodies and jaws that allow them to swallow prey whole. Snakes play important roles in ecosystems as both predators and prey.
Why are vestigal structures considered critical evidence of evolution?
Many species have vestigial structures, especially in the animal kingdom. Two good examples are the vestigial legs in whales and some snakes. This is clear evidence that whales and snakes are descended from creatures that had functional legs. This is strong evidence of evolution, since there is no other plausible explanation, religious or scientific, for vestigial structures.
Why is the pelvic girdle in snake is a vestigial?
The pelvic girdle in snakes is vestigial because they have lost their hind limbs during evolution. Since snakes no longer have hind limbs, the pelvic girdle serves no functional purpose and is reduced in size and structure.
How many legs have three snakes?
None - UNLESS you count the vestigial 'spurs' (remnants of legs that have gradually disappeared through evolution) that pythons have - in which case the answer would be six !
The tiny hip bones and leg bones present in some snakes are an example of?
Vestigial structures. Over time, the reptiles snakes descended from gradually began to use their legs less and less and so the limbs disappeared. The hip and leg bones present are essentially useless to the snake and are "left over" from their evolution. That is what a vestigial structure is (e.g. appendix in humans is also vestigal; we don't use it).
How are scientists able to explain vestigial structures found in whales and some snakes?
These vestigial structure, hip bones and leg bones, attest to the land dwelling ancestor of whales and the leg bearing ancestor of snakes. The inference is rather simple in whales. How else could a water swimming animal posses vestigial legs. For light amusement read some of the creationist non explanations for these vestigial markers. talkorigins.org
Do snakes have a femur?
Yes. But it is a vestigial structure, meaning the ancestors needed them, but they are useless to the current creature.
Do snakes have evidence that they had legs?
no.
How Snakes are considered?
Snakes are reptiles.
Whales snakes and dolphins all have vestigial bones that indicate they once had hind limbs Living whales snakes and dolphins do not have hind limbs This is an ex?
There is no answer for this question because it does not make any sense.
How can you see a snakes legs?
Yes, the vestigial hind legs of boas and pythons show up as spurs on either side of the vent.
What are 2 limbs that are vestigal and why?
There are vestiges of leg bones and pelvises in cetaceans and snakes. The wings of ostriches and other flightless birds are also vestigial. These limbs are vestigial because although they are homologous to the legs and wings of other creatures, they have little or none of their function.
How is a human skeleton the same as a snake skeleton?
Both humans and snakes have an exoskeleton made of bone and some cartilage. Both poses a skull, a jaw, vertebrae, and ribs. Some snakes also have a vestigial pelvis.
