Which British naturalist used thousands of plant and animal specimens?
Charles Darwin
Who was the naturalist that traveled the world to study plants and animals?
Charles Darwin set sail on the ship HMS Beagle on December 27, 1831, from Plymouth, England. Darwin was twenty-two years old when he was hired to be the ship’s naturalist. Most of the trip was spent sailing around South America. There Darwin spent considerable time ashore collecting plants and animals.
What did Darwin discover on the Galapagos Islands?
finches
Who is Darwin and what did he do?
Charles Darwin, in full Charles Robert Darwin, (born February 12, 1809, Shrewsbury, Shropshire, England—died April 19, 1882, Downe, Kent), English naturalist whose scientific theory of evolution by natural selection became the foundation of modern evolutionary studies.
What is Charles Darwin theory of evolution all about?
Charles Darwin’s theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.
What continents did Darwin visit on his voyage?
In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship’s naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos.
What are the 4 parts of the theory of natural selection?
Darwin’s process of natural selection has four components.
- Variation. Organisms (within populations) exhibit individual variation in appearance and behavior.
- Inheritance. Some traits are consistently passed on from parent to offspring.
- High rate of population growth.
- Differential survival and reproduction.
What important observations did Darwin make on his voyage?
Darwin observed living things as he traveled. He thought about relationships among those organisms. Darwin’s important observations included the diversity of living things, the remains of ancient organisms, and the characteristics of organisms on the Galápagos Islands.
What were the three patterns that Charles Darwin observed on his voyage that led him to accept and form his ideas of evolution?
As he traveled, Darwin noticed three distinctive patterns of biological diversity: (1) Species vary globally, (2) species vary locally, and (3) species vary over time. Darwin noticed that different, yet ecologically similar, animal species inhabited separated, but ecologically similar, habitats around the globe.
What is an example of species vary globally?
Species Vary Globally – different, yet similar, animal species inhabited separated, but similar, habitats around the globe. example: rheas, ostriches, & the emu.
Who observed variations in the characteristics of animals and plants on the different island of the Galapagos?
How is survival of the fittest related to a population’s environment?
How is the process of survival of the fittest related to a population’s environment? →In the survival of the fittest, individuals that are best suited to their environment survive and reproduce most successfully.
Which is a major concept included in Lamarck’s theory of evolution?
chapter 15

| Jean Baptiste Lamarck proposed that organisms | Have an innate tendency toward complexity and perfection |
| Which is a major concept included in Lamarck’s theory of evolution? | Body structure can change according to the actions of the organisms |
Which of the following best describes how Lamarck would explain giraffes and their long necks?
the most. Which of the following best describes how LAMARCK would explain giraffes with long necks? Some giraffes have acquired longer necks by stretching to reach food and passed that trait on.
Who proposed that the selective use or disuse?
Jean-Baptiste Lamarck was one of the first scientists to see that evolution occurred. He proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetimes. Scientists now know that was incorrect, but his general ideas about adaptation was correct and influenced Darwin.
Who came up with a very similar theory about evolution around the same time as Charles Darwin?
Charles Darwin is more famous than his contemporary Alfred Russel Wallace who also developed the theory of evolution by natural selection. Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the 500s B.C.E.
What are 7 kinds of evidence that support Darwin’s theory of evolution?
Evidence for evolution: anatomy, molecular biology, biogeography, fossils, & direct observation.
What can be used as evidence for evolution?
Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos.
How do fossils prove the theory of evolution?
The fossil record Fossil remains have been found in rocks of all ages. Fossils of the simplest organisms are found in the oldest rocks, and fossils of more complex organisms in the newest rocks. This supports Darwin’s theory of evolution, which states that simple life forms gradually evolved into more complex ones.
