The human appendix (a small sac near the junction of the small and large intestine) is homologous to a structure called the "caecum", a large, blind chamber in which leaves and grasses are digested in many other mammals.
What else can I help you with?
Homologous structure that is greatly reduced in size is called?
A homologous structure that is greatly reduced in size is known as a vestigial structure. These structures are remnants of organs or body parts that had a function in ancestors but are no longer used in modern organisms. Examples include the human appendix and the hip bones in whales.
What structure in the human is analogous to the cecum?
appendix
What is a homologous structure to the human forearm?
the leg of a horse
Which would be a homologous structure to a human?
A bird's wing bone
What structure describes scientists believe human arms and whale flippers were inherited from a common ancestor?
Homologous add Perhaps to a human's foot.
Is the human forelimb a homologous structure?
Yes, the human forelimb is considered a homologous structure because it shares a common evolutionary origin with the forelimbs of other vertebrates. Despite variations in function and appearance, the underlying bone structure and developmental pathways are similar across species.
What is the appendix use for in human?
The appendix is not really needed in the human body, it is just there to help your body with digestion.
Two species have homologous structures what do these homologous strcutures show about the evolutionary relationship between the two species?
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
The human appendix is a structure that suggests that humans evolved from plant-eating ancestors?
vestigal
Are the appendix in humans and horses homologous?
Yes, the appendix in humans and horses is considered homologous as both structures arise from similar embryonic tissues. However, their functions and structural characteristics differ significantly. In humans, the appendix is a small, tube-like structure that may play a role in gut flora maintenance, while in horses, the cecum serves a more prominent digestive function, and they do not have a distinct appendix. Thus, while they share a common origin, their roles in the respective species are not the same.
Which type of anatomic structure are birds wings and human arms when compared to each other?
Homologous
The muscles that move the human ear appear to be?
vestigial structure-such as the human appendix, doesn't seem to have a function and may once have functioned in the body of an ancestor..:)
