Darwin and theory of common descent states that all organisms?
Darwin's theory of common descent states that all organisms _____.
Darwin’s theory of common descent states that all organisms?
Darwin's theory of common descent states that all organisms evolved from past organisms.
According to Darwin's theory of evolution all species on Earth are united by what?
common descent
What are two ideas about evolution that were proposed by scientists in the 18th century?
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
What is a Common theory?
A common theory is a theory which has not been proven or a theory without evidence.
What does the biogeography or fossils support evolutionary theory?
Biogeography, which studies the distribution of species, supports evolutionary theory by showing patterns of species distribution that align with the idea of common ancestry and evolution. Fossils provide physical evidence of species that have existed in the past, showing transitional forms and demonstrating the gradual changes in organisms over time, supporting the concept of descent with modification proposed by evolutionary theory.
Darwin and theory of common descent states that all organisms?
Darwin's theory of common descent states that all organisms _____.
Does the theory that organisms share a common ancestor is known as common descent?
Yes, that is true.
What should each species on Earth today have according to the theory of Common Descent?
The theory of Common Descentbelievesthat all species on earth have a common ancestor.
Darwin’s theory of common descent states that all organisms?
Darwin's theory of common descent states that all organisms evolved from past organisms.
According to Darwin's theory of evolution all species on Earth are united by what?
common descent
According to Darwin's theory of evolution all species are united by what?
They are united by common descent
How do fossil and biochemicals support the theory of evolution?
Fossils provide physical evidence of extinct organisms and show a progression of forms over time, supporting the concept of evolution through natural selection. Biochemicals, such as DNA and proteins, can be compared between different species to reveal shared genetic sequences, indicating a common ancestry and supporting the theory of evolution.
Are fossils evidence of continental drift?
Yes, fossils are evidence of continental drift because similar fossils have been found on different continents that are now far apart. This suggests that these continents were once connected, supporting the theory of continental drift.
Why fossils support the theory of continental movement?
Fossils found on different continents with similar characteristics suggest that these landmasses were once connected millions of years ago. As continents drift apart, similar fossils can only be explained by the movement of landmasses over time, supporting the theory of continental drift. This provides evidence that different continents were once part of a single supercontinent, such as Pangaea.
What is the evolutuionary theory?
The theory of descent with modification.
What are two ideas about evolution that were proposed by scientists in the 18th century?
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.
