What are the three types of evidence that suggest various organisims are related through common descent?
Fossil Records, Comparative Anatomy, & Molecular Evidence
Is there no evidence of a common ancestor?
There is lots of evidence for a common ancestor but I suggest you look at wikipedia's evidence for common descent or Talk origins 29 evidence for evolution.
Describe three lines of evidence that support the theory of evolution Provide an example for each line of evidence you list?
Fossil Record the ordered array in which fossils appear within layers of sedimentary rocks. Comparative Anatomy comparison of body structures in different species, which give signs of common descent. Biogeography the geographical distribution of species.
What is the role of fossils in supporting the theory of common descent?
There have been many fossils of intermediate types discovered that provide strong support for the theory of common descent.
What evidence is there to evolution?
The evidence for evolution is extensive and multi-layered, too much for me to cover comprehensively. The Wikipedia article 'Evidence of common descent' has many subcategories. these are: Evidence from genetics Evidence from palaeontology Evidence from comparative anatomy Evidence from geographical distribution Evidence from comparative physiology and biochemistry Evidence from antibiotic and pesticide resistance Evidence from complex iteration Evidence from observed speciation and adaptation Evidence from intraspecies modifications I would recommend the Wikipeidia article and I am sure there are a large number of YouTube videos dedicated to the subject.
How Are homologous structures such as forelimbs evidence for common descent?
It shows the organism has same structures as its relatives.
What does the evidence for evolution suggest?
That evolutionary theory is accurate, at least in its fundamental theses: common descent and natural selection.
Identify two ways that organisms can be compared to provide evidence of evolution from a common ancestor?
You may use a brace map to determine common ancestors, look at physical structures of the skeletal system, or homologous genes.
What provide evidence of common ancestry amongisms?
Simularities in DNA sequence
What evidence do we have of evolution?
Evidence of common descent of living organisms has been discovered by scientists researching in a variety of disciplines over many decades, demonstrating that all life on Earth comes from a single ancestor.
Examples of biochemical evidence of evolution?
Physiological similarities suggest the species evolved from the same ancestor.
What is the type of descent that explains why all species are linked in a single tree of life?
Common descent
