Scientists found that both segmented worms and arthropods have a hollow space in their bodies to hold their organs. They both also have larvae stages early on in their life cycle.

Why do scientists think arthropods and segmented worms have common ancestor?
all arthropods have segmented bodies, just certain ones, have a round segmented body, and others have a flat segmented body.
Why do humans and chicks develop similarly to reptiles?
because of a common ancestor of all vertebrates in Pre-Cambrian period, scientists says that they all will have a common development stage.
When two structures of two species are very similar what can scientists infer about both species?
evolved from a common ancestor that also had the structure bg
What is the common name of annelids?
Segmented worms
What evidence suggests that humans and bats have a common ancestor?
For one, both humans and bats are in the class Mamalia, which is reason enough to suggest that they come from a common ancestor. The modern classification system, developed by Linnaeus, and modified by scientists such as Darwin and Lyell, is based of common ancestors. So, all mammals come from a common ancestor. How do we know this? Well, all mammals share a peculiar trait: All mammals are completely indistinguishable at the pre embryonic stage. This proves that bats and humans come from common ancestry.
Why do scientists think arthropods and segmented worms have common ancestor?
all arthropods have segmented bodies, just certain ones, have a round segmented body, and others have a flat segmented body.
What do nematodes and arthropods have in common?
they both are segmented
Is a segmented body common to all arthropods?
Yes, segmented bodies, an exoskeleton made from chitin, and joint appendages are common features of arthropods.
Do mollusks and segmented worms share a common ancestor?
Yes these two share common ancestors.
What 3 common characteristics do all arthropods share?
Jointed legs, exoskeleton, growth by molting.
What characteristics do insect such as honeybees have in common with all other arthropods?
Bees are classified as arthropods because of their characteristic segmented bodies, an exoskeleton made from chitin, and joint appendages.
What 3 things do all Arthropoda have in common?
Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and jointed appendages.
What is the evidence which shows that mollusks and annelids share a common ancestor?
Mollusks and segmented worms have a one-way digestive system, a separate mouth and anus, and their larvae are very similar. This is the best evidence that they have a common ancestor.
Which of the following is true about the supergroups and a common ancestor?
Scientists know that the supergroups do not share a single common ancestor but do not know where in time they branch off from each other:)
Why do scientists think arthropod and semented worms have a common ancestor?
Scientists believe this because they have a similar body model.
What are the roundworms ancestor?
There is some debate about what other groups the nematodes, or roundworms, are most closely related to, and therefore from what group they descended. Nematodes are classified as being in the clade Ecdysozoa which also includes arthropods. If nematodes are truly closely related to arthropods then they share a common ancestor.
What does a branch point in a cladogram represent?
The branch point in a cladogram represents a specific ancestor that is separated into two or more species. For example a leopard and a house cat share a common ancestor. A similar example is that a wolf shares a common ancestor with the leopard's and house cat's ancestor but the wolf's ancestor lived longer than the leopard's and house cat's ancestor. Scientists use something called cladistics to determine the one common ancestor that multiple species have in common.
