Comparative embroyology allows us to see the similarities between embryo's of related species. Therefore, similarities between two organism's in the embryo signal that at some point, those two organism's were related. The earlier those similarities disappear, the farther apart evolutionarily the two organisms are.

When was natural selection accepted?
Natural selection was formally accepted as a major mechanism of evolution in the 19th century with the publication of Charles Darwin's seminal work "On the Origin of Species" in 1859. However, the concept of natural selection was not widely accepted until later in the 20th century when more evidence in support of the theory accumulated.
Darwin proposes that all species of the natural world are in a constant state of evolution whereby natural selection plays a pivotal role in the survival of species Do you agree with this theory of yo?
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
Darwin's claim that all of life descended from a common ancestor is best supported with evidence from?
the fossil record, comparative anatomy, molecular biology, and biogeography. These lines of evidence all point towards a shared ancestry among different species, providing support for Darwin's theory of evolution by natural selection.
Why do scientists believe in natural selection?
Scientists believe in natural selection because it is a well-supported and extensively studied mechanism that explains how species evolve and adapt to their environment over time. The evidence for natural selection comes from various fields of study, including genetics, paleontology, and ecology, providing a strong foundation for understanding the diversity of life on Earth. Additionally, the observations of natural selection in action, such as antibiotic resistance in bacteria or beak size in finches, further support its validity as a key driver of evolution.
Joins together the ideas of modern genetics with Darwin's theory of natural selection?
Modern genetics has provided evidence to support Darwin's theory of natural selection by showing how variations in genes can lead to differences in physical traits among individuals of a species. Genetic research has also demonstrated how the process of natural selection acts on these genetic variations to drive evolutionary changes in populations over time. By understanding how genes and natural selection interact, scientists can better explain the mechanisms behind the diversity of life on Earth as proposed by Darwin.
What evidence is there that evolution has occurred?
Evidence for evolution includes fossil records showing transitional forms between species, genetic similarities between different species, and observations of natural selection leading to changes in populations over time. Additionally, comparative anatomy and embryology provide further support for the theory of evolution.
How does genetic variation support Natural Selection?
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
What are five areas of evidence that support evolutionary theory?
Fossil record showing transitional forms between different species. Genetic similarities between organisms indicating shared ancestry. Biogeographical distribution patterns supporting species divergence and modification over time. Comparative anatomy and embryology demonstrating common structures and developmental patterns. Observations of natural selection and adaptation in living populations.
What types of evidence do scientists use to support evolution?
Scientists use various types of evidence to support evolution, including fossil records showing transitional forms, the distribution of species around the world, comparative anatomy and embryology, genetic similarities among organisms, and observed instances of natural selection. These different lines of evidence provide a strong basis for understanding the process of evolution.
Is the theory true that the theory of evolution is supported by a wide range of biological evidence?
Yes. If evolution was not widely supported by evidence, then it would be regarded as a hypothesis rather than a theory.
Who is the scientist that collected so much information to support natural selection in 1809?
Charles Darwin, the creator of the theory of natural selection, was born 1809.
Is evolution true or false reasons why?
true Answer The Theory of Evolution by Means of Natural Selection is accepted by most, almost all, scientists as an excellent account of how life must change and diversify and adapt across time. Evolution is considered factual and thus true by most scientists. The reason for this is the huge amount of evidence, which comes from comparative genetics, comparative genomics, comparative cytogenetics, biogeography, comparative morphology, comparative biochemistry, comparative behaviour and the fossil record.
What did Charles Darwin used the least to support natural selection?
Charles Darwin used data on artificial selection the least to support his theory of natural selection. While artificial selection played a role in shaping his understanding of how traits can change over generations, he focused primarily on observations of variation in nature and the role of competition and adaptation in driving the process of natural selection.
What proof do we have evolution taking place?
Evidence for evolution includes the fossil record, comparative anatomy, molecular biology, and observed instances of natural selection. These different lines of evidence all support the concept of biological evolution occurring over time.
What is the kind of evidence used to support evolutionary theory?
Evidence used to support evolutionary theory includes the fossil record showing the progression of species over time, comparative anatomy and genetics showing shared traits among different species, and the observation of natural selection acting on populations leading to adaptation and speciation.
What were the sources of evidence Darwin used for his theory of evolution?
Darwin used various sources of evidence to support his theory of evolution, including the fossil record showing patterns of species change over time, comparative anatomy and embryology showing similarities between different species, biogeography illustrating patterns of species distribution, and selective breeding experiments demonstrating artificial selection. Additionally, he observed natural variations within species and proposed the mechanism of natural selection to explain how advantageous traits become more prevalent in a population over generations.
What have you learned about heredity and genetics that could support Darwin's theory of natural selection?
Understanding how genetic variation can be inherited from one generation to the next helps support Darwin's theory of natural selection, as it provides the basis for the variability upon which natural selection acts. The mechanisms of inheritance, such as dominant and recessive traits, allow for the passing down of advantageous traits that can confer a survival advantage, leading to their increased prevalence in a population over time through natural selection. By observing how traits are passed on and how they can change within a population over generations, we can see how natural selection can drive the evolution of species.
