If an animal has a vestigial structure what can a biologist infer about the animal's evolutionary history?

that the animal once had a use for that structure depending on where it lived. or that it decended from an animal that had that structure and used it.

Who is someone that studies adaptations in animals?
Charles Darwin, often times considered the Father of Evolution, studied the evolution of animals. He was coined the first Evolutionary Biologist, and where the term came from.
Which organ is absent or vestigial in animals living in burrows?
The blind mole rat has a thin layer of skin covering its eyes, which is considered to be vestigial. There are also cavefish which have eyes that are vestigial. (There are also other vestigial traits in other animals that do not burrow.)
How are vestigial structures not removed by natural selection?
Yes, because vestigial structures can be harmful. For example, some humans are now born without an appendix which ensures they will not be killed via appendicitis. Having a smaller expression of a vestigial structure, like having a smaller appendix, saves on the energy wasted in maintaining an unneeded structure.
What biologist attempts to gain insight into the natural history of animals plants and microorganisms using the concept that species change over time?
the correct answer is Evolutionary or A.... for Plato Biology course
Do all animals have a tail?
Yes, all chordates have a tail sometime during their development, although its not necessarily seen when the animal is adult. In many animals its a vestigial structure
What is the difference between homologous and vestigial?
Homologous refers to the similarity in structure and function of different parts and organs of different animals. For example, a human hand is homologous to a dog paw; a bird's wings are homologous to human arms. Vestigial refers to parts and organs that, due to historic evolution and development, may no longer be necessary. For example, the tail bone has no purpose or function in modern human structure, and neither do some of the muscles that surround the human ear. Also, whales have unnecessary bones in the back portion of their bodies that appear to have once been used to support legs; this indicates, from an evolutionary perspective, that whales may once have been land animals. Now that they live only in water, those remaining leg bones are vestigial.
What does vestigial mean and give one example?
The word 'vestigial' means not fully developed in mature animals Vestigial is a small remnant of something that was once much larger.
What do marine biologist do weekly?
Weekly, Marine Biologist study animal medicine the undersea habitats of animals, and the animals themselves.
Whales have vestigial legs This suggests they?
That they evolved from land animals.
What do marine biologist do to help us?
Marine biologists study the habitat, food, shelter, mode of nutrition, morphological and anatomical structure of body of those animals.
What biologist studies animals?
all biologists sudy animals
What animals do marine biologist study?
animals in the ocean/sea
