What class of aquatic creatures evolved from artiodactyla?
Whales and dolphins are believed to have evolved from artiodactyls. This is supported by genetic and anatomical evidence, showing a close evolutionary relationship between these groups.
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?
A symbiotic relationship is defined as a close relationship between two organisms of different species. This relationship can be mutually beneficial (mutualism), one-sided benefit (parasitism), or neutral (commensalism).
Who are the snakes are close cousins to?
Snakes are close cousins to lizards, as they both belong to the same group of reptiles called Squamata. They share a common evolutionary ancestor and have similar characteristics such as scales and a forked tongue.
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
Why are echinoderms considered to be closely related to corroded?
Echinoderms, such as starfish and sea urchins, are considered closely related to chordates, including corals, due to their shared evolutionary lineage within the deuterostomes, a major group of animals characterized by specific developmental features. Both echinoderms and chordates exhibit bilateral symmetry at some stage of their development and share common genetic and embryological characteristics. Moreover, molecular studies have shown significant genetic similarities between these groups, supporting their close evolutionary relationship.
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.
How close are humans to chimps in terms of genetic similarity and evolutionary relationship?
Humans are about 98-99 genetically similar to chimpanzees, making them our closest living relatives in terms of evolutionary relationship.
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 are echinoderms closely related to chordates?
most chordates are vertebrates, but some are not. invertebrate chordates belong to two of the subphylum of chordates. Cephalochordata and Urochordata. both invertebrate and vertebrate chordata have a dorsal nerve cord, a notochord, pharyngeal pouches and a postanal tail.
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.
Why evolutionary relationship are stronger between organism that have close biochemical similarities than between organism that do not close biochenical simillarities?
Organisms with close biochemical similarities likely share a more recent common ancestor, leading to a stronger evolutionary relationship based on a more recent divergence from a common gene pool. This shared genetic heritage results in similar biochemical pathways and molecular mechanisms, reinforcing the evolutionary relationship between closely related organisms. In contrast, organisms with greater biochemical differences likely diverged from a common ancestor further back in evolutionary history, leading to a weaker relationship due to more distinct genetic and biochemical characteristics.
How does the comparison of ape DNA and human DNA provide insights into the evolutionary relationship between the two species?
The comparison of ape DNA and human DNA reveals similarities that suggest a close evolutionary relationship between the two species. By analyzing the genetic similarities and differences, scientists can trace the evolutionary history and understand how humans and apes are related through a common ancestor.
What other phylum might be considered our close relatives?
Our close relative phylum are the echinoderms because they are also deuterostomes.
What similarities in DNA and protein sequences do humans and chimpanzees share?
Humans and chimpanzees share about 98.7 of their DNA sequences and have similar protein sequences due to their close evolutionary relationship.
The molecular and structural similarities observed among these organisms is best explained by?
their common evolutionary ancestry and shared genetic material, which have led to the conservation of certain molecular and structural features. This indicates a close evolutionary relationship and a common ancestor from which these organisms have diverged over time.
What class of aquatic creatures evolved from artiodactyla?
Whales and dolphins are believed to have evolved from artiodactyls. This is supported by genetic and anatomical evidence, showing a close evolutionary relationship between these groups.
