How did Lyell's book of principles of geology help Darwin see that natural selection over many generations could explain species modification?
Lyell collected overwhelming evidence that the Earth's surface is constantly changing and did much to advance the idea that the Earth changes through time (inorganic evolution). Lyell also put forth the idea that changes from one rock layer to another may take millions of years, which indicated that Earth much older than was previously thought.

What terms did Darwin use to explain how new species emerged?
Charles Darwin used the terms "natural selection" and "descent with modification" to explain how new species emerged. Natural selection refers to the process by which individuals with favorable traits are more likely to survive and reproduce, leading to the gradual evolution of species. Descent with modification denotes the idea that species evolve over time, sharing a common ancestor while developing distinct characteristics. Together, these concepts illustrate the dynamic nature of species and their adaptation to changing environments.
Explain the difference between artificial and natural selection?
Artificial selection is anthropogenic -- humans interfere with nature to determine what traits get passed on, whereas natural selection is when through sexual reproduction the traits passed on are determined by survival of the fittest.
Is it true that natural selection helps explain how new species develop?
Yes, it is true.
What term did lamarck use to explain?
Lamarck used the term "inheritance of acquired characteristics" to explain how organisms could pass on traits they acquired during their lifetime to their offspring. He believed that environmental challenges would lead to physical changes in an organism, which could then be inherited by future generations. This idea was a significant early contribution to evolutionary thought, although it was later largely replaced by Darwin's theory of natural selection.
What are the 5 theories of evolution by Charles Darwin?
Charles Darwin's theory of evolution is primarily encapsulated in the concept of natural selection, but it can be expanded into several key ideas: Variation: Individuals within a species exhibit variations in traits. Inheritance: Traits can be passed down from parents to offspring. Overproduction: Organisms tend to produce more offspring than can survive. Survival of the Fittest: Individuals with advantageous traits are more likely to survive and reproduce. Descent with Modification: Over time, these advantageous traits become more common in the population, leading to evolutionary change. These concepts collectively explain how species adapt and evolve over generations.
How did Lyell's book principles of geology help Darwin see that natural selection over many generations could explain species modification.?
With Lydell's book , the premise that stratification can take millions of years, it allowed Darwin the freedom to accept that the world was much older than current conjecture. Armed with that notion, Darwin realized there was enough time for organisms to develop from ancestors.
How did Darwin explain the patterns of distribution of plants and animals?
He explained them in terms of descent with modification, common descent and natural selection.
Which two ideas did Darwin use to explain evoultion?
Darwin used the ideas of natural selection and descent with modification to explain evolution. Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce, passing those traits on to their offspring. Descent with modification refers to how species change over time through the accumulation of small changes in their inherited traits.

How do experiments with selective breeding help explain natural selection?
Experiments with selective breeding illustrate the principles of natural selection by demonstrating how specific traits can be enhanced or diminished in a population over generations based on human choice. In selective breeding, individuals with desirable characteristics are chosen to reproduce, leading to a concentration of those traits in subsequent generations. This mirrors natural selection, where environmental pressures favor certain traits, allowing individuals best suited to their environment to survive and reproduce. Both processes show how variations within a species can lead to evolutionary changes over time.
What did Darwin claim the mechanism that caused evolution?
Natural selection with modification of traits. He could explain natural selection, however he had no explanation for modification of the traits from generation to generation (this had to wait for Gregor Mendel's theory of genetics, and the later discovery of nucleic acids and Watson and Crick's study of DNA to explain the storage of genetic information chemically).

What are the principles of a food chain?

When Darwin published his theory of natural selection in 1859 he could not explain how traits were passed on to offspring what helped complete Darwin's theory of natural selection?
The discovery of discrete inheritance by Gregor Mendel. This genetic finding was combined with evolutionary findings to form the modern evolutionary synthesis that is still, with modification, the theory of evolution by natural selection today.
How can the darwinian concept of descent with modification explain the evolution of such complex structures as an aye?
Eyes are easy. Just look at all the intermediates. From eye spots to cup eyes past pinhole eyes all the way to camera eyes. This progression easily shows the concept of descent with modification.
