Darwin used various forms of evidence to support his theory of evolution by natural selection, including observations of variation within species, the fossil record, comparative anatomy, and biogeography. His work also drew on principles of population genetics and the idea of descent with modification.
Charles Darwin used selective breeding as evidence for evolution to illustrate how humans could influence the traits of domesticated animals and plants through controlled reproduction. He observed that breeders could enhance specific characteristics over generations, which paralleled the natural selection process in nature. This demonstrated that variation within species could lead to significant changes over time, supporting his theory that species evolve in response to environmental pressures. Thus, selective breeding served as a practical example of how small changes can accumulate to create new forms of life.
The earliest forms of energy utilized by humans were likely fire, animal power (such as muscle power from domesticated animals), and wind power for sailing ships and windmills. These forms of energy were essential for cooking, transportation, and mechanical work.
No, Darwin believes that land animals traveled to the Galapagos Islands and adapted to the islands in different ways, causing them to become a different species.
the variation in the forms of adult vertebrates probably arose through mutations in dominant genes
Charles Darwin
Various is an adjective; variation or variety are noun forms.
Neolithic people primarily traveled by foot, as there were no domesticated animals for transportation at that time. They likely walked or used crude forms of transport such as rafts, canoes, or sledges. As agricultural practices developed, they would have also used animals such as oxen or donkeys to assist with transportation.
Darwin collected thousands of specimens across the world. Like other naturalists before him, Darwin noted similarities in the species that contributed to their classification. But Darwin also had fossils detailing changes that had occurred over vast stretches of time. Darwin noted pigeon breeders could introduce stable changes in a population via a process of artificial selection. He also saw that nature introduced its own changes in species. Although there is a huge diversity of life, Darwin saw how it was organized and how it must have changed over the ages. Not long after he published his theory, a fossil of Archeopteryx was discovered, showing the link between birds and dinosaurs. Later fossils of Neandertal were discovered, demonstrating the existence of multiple hominid species in prehistoric ages past.
Biodiversity means different types of plants and animals in one area.
Darwin was inspired by Thomas Malthus's idea that populations grow faster than the resources available to support them. Darwin applied this concept to the natural world, suggesting that individuals within a species compete for limited resources, leading to a struggle for survival. This struggle, along with natural variation and heritability of traits, forms the basis for natural selection, where individuals with advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring.
Charles Darwin introduced the theory of evolution through natural selection, which posits that species evolve over time due to the survival and reproduction of individuals with advantageous traits. He emphasized the importance of variation within species and the role of environmental pressures in shaping these traits. Additionally, Darwin's work highlighted the interconnectedness of life forms, suggesting that all species share a common ancestor. His seminal work, "On the Origin of Species," laid the foundation for modern evolutionary biology.
