Does echinoderms have a close evolutionary relationship with chordates?

Yes they do. Echinoderms, which include starfish, and chordates, which include humans are closely related in an evolutionary sense due to the way their embryos are formed in the early stages of development. Once past that point, the very obvious differences form.

How do scientists use geographical distribution to determine the evolutionary relationship?
Organisms that are close geographically are usually more closely related than those that evolved in widely separated areas of the world.
Which term is defined as a close relationship between two organisms of different species?
symbotic
What is the symbiotic relationship between a flea and moose?
It would never be a symbiotic relationship... the relationship would be parasitic (the flea benefiting from the blood and the moose being harmed from the taking of its blood). - Actually parasitism is a type of symbiotic relationship. any close relationship between two organisms is a symbiotic relationship no matter the conditions of said relationship
How did they first ever treat wild captive animals in zoos?
They extrapolated dose rates and suitable medical therapies from supposedly related species. E.g. Many seal species receive the same medical and surgical therapy as dogs based on their close evolutionary relationships.
What is the stripey pupil in a cats eyes called?
It's called an elliptical pupil, it basically is an evolutionary sight failure fail safe, though they are susceptible to cataracts it keeps there vision sharp and it allows the pupil to open and close much faster than our sorry little round pupil hehe, it's also used in there night vision, but I'm not sure how
Which type of animals are close to chordates from evolutionary point of view?
Chordates are the common ancestors of fish and sharks. They include lampreys and other types of primitive fish species that live in the sea.
Are echidna exoskeletons?
No. echinoderms have no exoskeleton.Related Information:Echinoderms are deuterostomes, a group belonging to the Phylum, Chordata but separate from the vertebrates, also of this phylum. While there is a close relationship between the echinoderms and the vertebrates, echinoderms are endoskeletal invertebrates.
Why evolutionary relationship are stronger between organism that have close biochemical similarities than between organism that do not close biochenical simillarities?
idk im tryna do it now? can anyone help me?? im stressed :/
Are vertebrates the largest group among the chordates?
Vertebrates are a subgroup of the chordates, meaning that all vertebrates are chordates, but not all chordates are vertebrates. Vertebrates are distinguished from other chordates by having backbones or spinal columns.All vertebrates have muscular systems that mostly consist of paired masses, as well as a central nervous system which is partly located inside the backbone (if one is present). The defining characteristic of a vertebrate is considered the backbone or spinal cord, a brain case, and an internal skeleton, but the latter is not true for lampreys, and the former is arguably present in some other chordates. Rather, all vertebrates are most easily distinguished from all other chordates by having a clearly identifiable head. Sensory organs--especially eyes--are concentrated at the foreend of the body, and there is pronounced cephalization.
What other phylum might be considered our close relatives?
Our close relative phylum are the echinoderms because they are also deuterostomes.
How do scientists use geographical distribution to determine the evolutionary relationship?
Organisms that are close geographically are usually more closely related than those that evolved in widely separated areas of the world.
How comparisons between the proteins of two species can yield data about their evolutionary relationship?
Take the protein cytochrome C. There is not one amino acid difference in structure between we humans and our close relatives, the chimpanzees. There are 51 differences between humans and single celled yeast in amino acids. We can strongly and simply infer from this data the evolutionary relationship among the three species mentioned here.
What is the scientific definition for hominid?
A hominid is a primate which has a close resemblance to the human race (H. Sapiens) and is considered to be a close evolutionary relative.
What is a close meaningful relationship between you and an individual called?
Friendship
What was a goal of a Whig party?

What is a close long term relationship between two or more species?
A symbiotic relationship is a close long term relationship.
What is affinity?
