horses and zebras are similar.They have common ancestors.
Scientific theory
Darwin drew ideas for his theory from observations of organisms on the Galápagos Islands, as well as from his studies of diversity and natural selection in various species around the world. His observations of finches, tortoises, and other animals on the Galápagos Islands were particularly influential in shaping his theory of evolution.
Darwin was influenced by ideas from other scientists such as Lamarck's theory of acquired traits and Malthus's principle of population. These ideas contributed to Darwin's concept of natural selection as the mechanism for evolution. Ultimately, Darwin's observations and synthesis of these ideas led him to develop his theory of evolution by natural selection, which revolutionized the field of biology.
Lucy's discovery of the Australopithecus afarensis remains was significant because it provided key insights into human evolution. The discovery showed that bipedalism preceded the development of a larger brain, challenging previous ideas about the evolution of early humans. Lucy's remains helped researchers better understand the timeline of human evolution and the characteristics of our ancestors.
Adaptation, natural selection, genetic variation, and speciation are key concepts that describe and influence the theory of evolution. These ideas explain how species change over time in response to their environment, leading to the diversity of life we observe today.
observations
Lamarck proposed the idea of "inheritance of acquired characteristics," suggesting that organisms can pass on traits acquired during their lifetime to their offspring. He believed that these acquired traits could lead to evolutionary change over time. However, his ideas have largely been discredited in favor of Darwin's theory of natural selection as the primary mechanism of evolution.
Observations are ideas that explains the authors idea.

The Galapagos Islands are significant to the theory of evolution because they inspired Charles Darwin's ideas on natural selection. Darwin's observations of unique species on the islands led to his theory that species can adapt and evolve over time to better survive in their environment.
Jean-Baptiste Lamarck published his ideas on evolution in 1809 in a book titled "Philosophie Zoologique." In this book, he proposed the theory of inheritance of acquired characteristics, which suggested that organisms could pass down traits acquired during their lifetime to their offspring.
Scientists test ideas about chemical evolution by using computer models.
