It also contains a remnant of the obliterated umbilical vein known as the round ligament of the liver.
Is the Lucy evolution hoax a widely accepted theory in the scientific community?
No, the Lucy evolution hoax is not a widely accepted theory in the scientific community. The discovery of the fossil known as Lucy, an early human ancestor, has been extensively studied and confirmed by multiple experts in the field of paleoanthropology.
Is there no evidence of a common ancestor?
There is ample evidence of a common ancestor for all life on Earth, known as the Last Universal Common Ancestor (LUCA). This is supported by various lines of evidence, including genetic similarities, shared biochemical pathways, and the universal presence of certain biomolecules across diverse species.
What is it called when body parts inherited from a common ancestor are no longer needed?
you must be talking about a vestigial structure. Like our vestigial "tail".
What term is associated with the the single called ancestor theory?
The single called ancestor theory is also known as the monogenism theory, which proposes that all humans are descended from a single pair of ancestors. This theory contrasts with the polygenism theory, which suggests that different groups of humans have separate origins.
An early ancestor of humans are called what?
An early ancestor of humans is called Australopithecus. This species is known for its upright posture and bipedal locomotion, and is considered an important transitional form in human evolution.
What does the presence of Similar genes in very dissimilar organisms imply?
The presence of similar genes in very dissimilar organisms implies a common ancestor. This suggests that these organisms share a common evolutionary history and have inherited these genes from a common ancestor. The concept is known as homology.
Type of hominid scientists believed was the common ancestor for several types of early humans?
Scientists believe that the common ancestor for several types of early humans, such as Homo neanderthalensis and Homo sapiens, was a hominid known as Homo heidelbergensis. This species is thought to have lived in Africa around 700,000 years ago and eventually migrated to Europe and Asia.
The ancestor of the modern oboe is known as the?

What is the cavemans closet ancestor?
There were no human species known as "Cavemen".
Any structure that is reduced in function in a living organism but may have been used in an ancestor is known as a vestigial structure?
vestigial organ is for example"appendix"in human beings.another example is the"tail bone"in human beings.
What animal was ambulocetus an ancestor to?
Ambulocetus, is the ancestor of the whales. It was known as the walking whale because it could walk on land, though it spent most time in water.
How can you say that the relation is a function?
A relation is a function if every value in the domain is mapped to only one value in the range. A non-mathematical example is mothers. Leaving aside surrogacy, every person has only one mother. Therefore the relation f(x) = x's mother is a function. But f(x) = x's ancestor is not a function because everyone has loads of ancestors. They may not all be known but that is not relevant.
What is the oldest genus of hominids?
The oldest genus of hominids is Ardipithecus, dating back to around 4.4 million years ago. Ardipithecus is considered an early human ancestor and is known for being one of the earliest bipedal primates.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
What is a sharovipteryx dinosaur?
It was a small, early gliding dinosaur. It is reputably known for having membranous wings on its hind legs, whereas most pterodactyls had it on their front legs. It is only about eight inches long with a long tail, and it is thought to be an ancestor to pterosaurs.
What ancestor is the one that has given rise to two or more lines of descent?
A common ancestor that gives rise to two or more distinct lines of descent is known as a "common ancestor" or "ancestor of divergence." This individual represents the point in the family tree where two or more branches split off and evolve independently over time.
