Scientific investigation is crucial in the development of the Theory of Natural Selection. This was illustrated by Charles Darwin and Alfred Russel Wallace in the 19th century, who used systematic observation, measurement, and experimentation to formulate the theory that diversity of life arose gradually through natural selection. A notable example is Darwin's research on finches in the Galapagos Islands.
The role of scientific investigation in the development of the Theory of Natural Selection is crucial. Scientific investigation involves the systematic observation, measurement, experiment, and the formation of theories or hypotheses, which are then tested.
In the 19th century, Charles Darwin and Alfred Russel Wallace independently devised the Theory of Natural Selection which proposed that the diversity of life arose through gradual changes in populations over time. They built this theory based on years of careful observation, note-taking, and hypothesis-testing - in essence, systematic scientific investigation.
For example, Darwin observed different variations of finches across the Galapagos Islands and made notes on their physical traits and habitats. Through rigorous analysis of this data, he eventually proposed that each species of finch adapted over generations to best suit its environment via the mechanism of natural selection.
So, scientific investigation played a fundamental role in the formulation and further development of this transformative biological theory.

Fish, poultry, lean meats, and nuts should be consumed for which of the following nutrients?
A. calcium
B. carbohydrates
C. protein
D. vitamin D
Answer: C. Protein
Answer: Fish, poultry, lean meats, and nuts should be consumed protein.
Explanation:
Fish, poultry, lean meats, are seafood and they are highly rich in protein with a very low amount of fat. The ratio of fat and protein is about 5 grams in a 3-ounce serving and it consists of omega 3 fatty acid. Cashews, Pistachios, Almonds are the nuts rich in proteins approximately 8-18% protein.
