The appearance of the cavefish and the minnow suggests a common ancestry since they possess homologous structures. Based on observations made on the characteristics of the cavefish and minnow, the structures of the fins, tails, and overall shape of the bodies make the two types of fish seem exceedingly related.What about the internal structure of the cavefish and minnow suggest common ancestry? The arrangement of bones, muscles and other internal organs. 1.The minnow is found in open streams and has excellent eyesight. The cave fish is found in dark, cave streams. It is blind and has reduced, non-functioning eye parts.

What is the biggest difference between cave fish and minnow?
The minnow is found in open streams and has excellent eyesight. The cave fish is found in dark, cave streams. It is blind and has reduced, non-functioning eye parts.

Do similarities in bone structure suggest a common ancestry among these animals?
ARRANGED SIMILARLY YES IT SUGGESTS A COMMON ANCESTRY. THE SPECIES ILLUSTRATED HAVE SIMILAR BONE STRUCTURES SUGGESTING COMMON ANCESTRY. HOWEVER THOSE STRUCTURES HAVE DIFFERENT FUNCTIONS DEPENDING ON EACH SPECIES’ ENVIRONMENT. THEY SHARE THE SAME FUNCTION.
What Four animals are listed as examples of homologous structures?
The common structures are the body parts but the difference is the structure. What four animals are listed as examples of homologous structures? Humans, dogs, birds, and whales.
Do you think cat and whale share structural similarities that would suggest they are closely related?
Homologous structures are similar physical features in organisms that share a common ancestor, but the features serve completely different functions. An example of homologous structures are the limbs of humans, cats, whales, and bats.
What do you think has become the most important adaptation of the cave fish think about senses explain your answer?
Blind cave fish compensate for their lack of sight by having a more sensitive lateral line system which detects vibrations or changes in pressure in the water. The lateral line is a specialized sensory organ found in fish.
Why did cave fish lose their eyes?
A new study reveals that the cave-dwelling form loses its eyes due to the silencing of more than two dozen genes—many of which are shared by humans and have been implicated in human eye disorders.

9.The appearances of the cave fish and the minnow can suggest some common ancestry as, though different sizes, they appear to have a similar basic structure, …
Do you think birds and insects have common ancestor Why or why not?
Analogous structures, on the other hand, can be represented by the wings of birds and of insects; the structures are used for flight in both types of organisms, but they have no common ancestral origin at the beginning of their evolutionary development.
Do cavefish have eyes?
Cave shrimp and cave fish don’t… because they don’t have eyes. Energy-saving eye loss, or the expensive tissue hypothesis, is one of a number of theories to explain why sighted animals that took up life inside caves evolved to be blind.
What animals have common ancestors?
All animals (including humans), plants and other organisms such as fungi and algae are Eukaryotes and share a common ancestor. And universal common ancestry would have it that all three domains themselves stem from a single root.
What is the common ancestor of reptile fish bird and mammals?
Amphibians, reptiles, mammals, and birds evolved after fish. The first amphibians evolved from a lobe-finned fish ancestor about 365 million years ago. They were the first vertebrates to live on land, but they had to return to water to reproduce.
What shows how organisms are related by descent from common ancestors?
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Which pair of animals show a correct example of homologous structures?
A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all derived from the same ancestral tetrapod structure.
What are 3 examples of homologous structures?
The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures. They are different and have a different purpose, but they are similar and share common traits.
Are beavers and elephants homologous or analogous?
For example, elephants’ tusks and beavers’ teeth are homologous structures, though they look quite different. Conversely, structures that look similar are not necessarily homologous. Similar structures that evolved independently are called analogous structures.
Is human whale and bat common ancestor?
Scientists have used computer analysis to read evolution backward and reconstruct a large part of the genome of an 80-million-year-old mammal. This tiny shrewlike creature was the common ancestor of humans and other living mammals as diverse as horses, bats, tigers and whales.
What is the strongest evidence for evolution from a common ancestor?
Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.
Which organisms evolved from the common ancestor Pakicetus?
The ancestor of today’s whales, the first cetacean, is believed to be Pakicetus, a quadruped measuring 1 to 2 metres long. Skeletons discovered in Pakistan indicate that the animal had typical artiodactyl ankles and a typical cetacean skull.
What kind of sensory adaptation Could you suggest the cave fish might have that will allow it to move in a cave including catching and eating food?
What kind of sensory adaptation would you hypothesize the cave fish has to allow it to navigate in a cave, including catching and eating food? The cave fish has special sense organs on its body surface that respond to the presence of different chemicals in the water. This would be analogous to our sense of smell.
Can Cavefish feel?
The blind cavefish has more sensors on its body, and each of them is twice as sensitive as a sighted fish’s receptors. It can feel its way around by judging disturbances in the ripples sent out by its own swimming body.
How does the pattern of embryological development provide evidence which supports common ancestry?
Evidence of an evolutionary common ancestor is seen in the similarity of embryos in markedly different species. Darwin used the science of embryology to support his conclusions. Embryos and the development of embryos of various species within a class are similar even if their adult forms look nothing alike.
How did the Mexican tetra evolve?
Evolution of the Mexican Tetra
Experiments have shown that cellular degeneration in the eye lens itself is key to the lack of eyes (Jeffery, et al, 2003). This phenomenon combined with natural selection over many generations, has, theoretically, led to the development of these eyeless fish.

What ability have many cave fishes lost *?
Many cave fishes are blind, and an experiment carried out by scientists suggests that blindness in these fishes is the result of a mutation that also improves their sense of smell.
Can cave fish hear?
They Can’t Hear You
In at least two species of cavefish, the opposite holds true. Daphne Soares, a neuroscientist at the University of Maryland, discovered cavefish only hear lower frequency noises, up to about 800 Hz. Ambient cave noise is normally around 1 kHz, a higher frequency than the cavefish can hear.
