How is the theory of evolution supported by evidence from the fossil recordc omparative anatomy comparative embryology?
The theory of evolution is supported by the fossil record, which reveals a chronological progression of species and transitional forms that illustrate gradual changes over time. Comparative anatomy shows similarities in the structures of different species, indicating common ancestry; for example, the forelimbs of mammals, birds, and reptiles have similar bone structures despite differing functions. Additionally, comparative embryology demonstrates that embryos of diverse species exhibit striking similarities in early development, further suggesting a shared evolutionary origin. Together, these lines of evidence reinforce the concept that species evolve and adapt over time through common descent.
What is the line of descent of a purebred animal called?
The line of descent of a purebred animal is called it's pedigree.
How do groups support the theory of evolution?
It's not groups that are the key bit of evidence for common descent, but nested hierarchies.In all lifeforms known to humankind, be it extant or extinct, the totality of similarities and differences forms a pattern of nested hierarchies - sets within sets within sets, each set having all the defining characteristics of the superset in addition to unique defining characteristics for itself and its subsets.There is only one testable explanation for such a pattern: common descent.
What is a Anagenesis?
Speciation without branching of the evolutionary line of descent.
Where does meursault live?
Meursault lives in Algeria, but is of French descent
What provides physical evidence of descent with modification over long periods of time?
Homologous Structures
How is the idea of common descent supported by example of homologous structures?
this question is to hard cant find it
How does homologous structures and analogous structures provide evidence that evolution has occurred?
Structures which are apparently different and performing different functions but their basic structure is similar are called homologous structures and indicate common ancestry eg. fore limbs of bat , whale , horse dog and man apparently different but are made up of humerus , radius , ulna , carpel , metacarpals and phalanges .
How do you use homologous structure in a sentence?
A homologous structure is an example of an organ or bone that appears in different animals, underlining anatomical commonalities demonstrating descent from a common ancestor.
What are the three types of evidence that suggest various organisims are related through common descent?
The three types of evidence that suggest organisms are related through common descent are anatomical evidence (similarities in body structures), molecular evidence (similarities in DNA sequences), and fossil evidence (transitional forms showing evolutionary changes over time).

Fossils show evidence of descent with modification?
yes they do

How biochemistry provides evidence of evolution?
Biochemistry is concerned with chemical substances and processes that occur within plants, animals and microorganisms. All life has prominent similarities at a molecular level. Organisms have basically the same:Genetic code in their DNAEnzymes used for basic metabolic processes, such as cellular respirationStructural Chemicals in their basic cell components, such as the phospholipids in cell membranes.

How does the existence of homologous structures support the theory of evolution?
When comparing earlier and later developments, homologous structures become more refined through time. When comparing common ancestors, we can compare the derivations of a homologous structure between two successors and also between the ancestor and each successor. We thus see several relationships between this and that, from 'right now', 'a little before now' and 'way back then'. For example, we see two species whose legs are very similarly structured, and then we find an ancestor that also possessed such a leg, except it was simpler or shorter or in a different ratio between sections. We can draw conclusions that the later species developed both from this earlier one, and that this earlier one died out, after its successors (which eventually became the newer species) could survive more often because they had better structured legs.
How can embryology be evidence for evolution?
Embryology provides evidence for evolution because it shows similarities in early developmental stages among different species. For example, vertebrate embryos often have similar structures early in development, reflecting their shared ancestry. These similarities suggest a common evolutionary origin and support the idea of descent with modification.
