What are three pieces of evidence for evolution?
Fossil record shows a progression of organisms from simple to complex forms over time. Comparative anatomy reveals similarities in bone structure and development between different species, indicating a common evolutionary ancestry. Genetic similarity and shared sequences in DNA among different species provide strong evidence for common ancestry and evolution.
How is homologous structures an example of evolution?
Though the forelimb of your cat or dog does not look much like your arms these are homologous structures that are almost identical bone for bone. This shows the common ancestry of all tetrapods and the closer common ancestry of you and your mammal pets.
Birds and bees have wings are their wings homologous features or analogous features?
The wings of birds and bees are an example of analogous features, as they have evolved independently in each group and do not share a common ancestry that possessed wings. Homologous features are those that are inherited from a common ancestor and are usually more similar in structure.
Which of these might be used to determine common ancestry of two different species of animals?
Fossil evidence
How does comparative anatomy not support evolution?
The comparisons between the anatomies of various organisms show common ancestry which supports evolution.
What are Structures in different organisms that share a common ancestry?
Examples of structures in different organisms that share a common ancestry include the pentadactyl limb in vertebrates (including humans, cats, bats, and whales) and the similar bone structure seen in bird wings, bat wings, and pterosaur wings due to a common ancestor from which they evolved. Another example is the vertebrate eye structure found in humans, birds, and octopuses, which have evolved independently yet share common features due to their shared ancestry.

What is a better indicator of the relationship between two organisms structure or function?
Oh honey, it's like asking if the chicken or the egg came first! Both structure and function play a role in understanding the relationship between organisms. Structure gives you the blueprint, while function shows you how that blueprint is being used. It's a package deal, you can't have one without the other, darling.
Similaritys between the chicken wing and human arm?
how can you relate the structures of a chicken wings and the human arm adapted to served different function ignore that first answer because it makes no sense.some similarities are: 1)both of them have elbows 2)both have epithelial,connective,muscle,and nervous tissue
What can homologies reveal about evolution?
Homologies, similarities in structure or genetic sequence among different species, can reveal common ancestry and evolutionary relationships. Studying homologies can help us trace the evolutionary history of organisms and understand how they have diversified over time. By comparing homologous traits, scientists can infer the shared ancestry and evolutionary pathways of organisms.
Who are the ancestors of people from Newfoundland?
While there is no one common ancestry, many of them have Irish ancestry.
What is the Strong evidence for the common ancestry of all vertebrates is?
The strong evidence for the common ancestry of all vertebrates is THE SIMILARITY OF THEIR EMBRYOLOGICAL STAGES.
What are 3 forms of evidence for evolution?
Fossil record: Shows a gradual change in species over time, supporting the idea of common ancestry and evolution. Genetic evidence: Similarities in DNA sequences between different species indicate shared ancestry and evolutionary relationships. Comparative anatomy: Homologous structures among different species suggest a common origin and evolution from a common ancestor.
Does the similarity in bone structure suggest a common ancestry amongst these animals?
Yes, the similarity in bone structure among different animals suggests a common ancestry. This phenomenon, known as homologous structures, indicates that these species evolved from a shared ancestor while adapting to different environments and functions. The presence of similar bone arrangements supports the theory of evolution, highlighting the genetic and developmental connections between diverse species.
What is the most common ancestry of your mom?
your nana
Analogous structures are evidence of?
Analogous structures are evidence of convergent evolution, where unrelated species evolve similar traits independently in response to similar environmental pressures. This supports the idea that evolution can lead to similar solutions to maximize survival and reproductive success in different lineages.
