Lamarck's explanation of evolution is based on two principles: use and disuse and the inheritance of acquired characteristics. Lamarck's "use and disuse" principle explained his belief that the body parts that are commonly used become larger and stronger such as a giraffe's neck, while those that are not used deteriorate and become smaller. He also believed that an organism could pass these modifications to its offspring through the inheritance of acquired characteristics. Thus, Lamarck thought that evolution is driven by the innate drive of organisms to become more complex. Although he was later proven wrong, he was insightful in observing and recognizing that gradual evolutionary change does exist.

What idea of Darwin's based on fossil and the modern organisms he found basically says that genetic changes are inherited by later generations?
Heredity is the idea of Darwin's based on fossil and the modern organisms he found basically saying that genetic changes are inherited by later generations.
Is The geologic time scale divided by major changes in the fossil record true?
Yes, the geologic time scale is typically divided based on major changes in the fossil record, called biostratigraphy. These divisions are used to categorize different periods in Earth's history based on the types of organisms that lived during that time.
Can fossil age determine organism changes related to the time scale?
The discovery of a fossil's age can be determined through methods involving radiometric dating. Fossils must then be compared to other organisms of that time period to determine changes to it.
How is the theory of evolution supported by fossil evidence?
When we examine the fossil record we see that the Earth has not always had the same living organisms living on it that it has today, but rather, there have been many changes, some gradual and some abrupt, over the past few billion years, and those changes show progressive alterations of exactly the kind that evolution would be expected to produce. The fossil record tells us that yes, life has evolved.
What can geologist learn from fossils?
Geologists can learn about the Earth's history, past environments, and changes in climate by studying fossils. Fossils provide evidence of how life has evolved over time and can help geologists understand the geological processes that have shaped the planet. They also help in dating rocks and determining the age of different geological formations.
What term describes coal as an energy source?
Fossil fuel.
Is fossil record considered scientific theory?
Probably more in the line of many converging pieces of evidence in support of theory. Theory is explanation and fossils are just mineralized bones in the rock. which need and explanation. The fossil record supports the theory of evolution by natural selection and, some say, the theory of punctuated equilibrium.
What word describes where fossil fuel comes from?
The word that describes where fossil fuel comes from is "deposits." Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of ancient plants and animals that were buried and subjected to heat and pressure over millions of years in geological deposits. These deposits are typically found in sedimentary rock layers beneath the Earth's surface.
How are fossils an example of evolution?
Fossils show certain species underwent small changes over a period of years the rock in which the fossil is encased dates the fossil and so they can put them in order to show the progression of the physical changes
A very simple explanation of how fossils or archaelogical age determine by a very simple example?
By measuring the amount of carbon in the fossil the archaeological age.
What is the answer to this describes a organism whose tissues are completely replaced by minerals?
An organism whose tissues are completely replaced by minerals is a fossil.
If similar fossil collections are found on two continents now widely separated what is a possible explanation?
If similar fossil collections are found on two widely separated continents, a possible explanation is the theory of continental drift, which posits that continents were once part of a single landmass called Pangaea. Over millions of years, tectonic plate movements caused these landmasses to drift apart. Another potential explanation could be that these regions were once connected through land bridges or shared ecosystems before becoming isolated, allowing for similar species to evolve and leave similar fossil records.
Time unit based on major striking and world wide changes in types of fossil presents?
The time frame does change the fossil world wide. The fossil in today's present would be different then it would be years ago.
What would be the changes if the fossil fuels are used up?
The world will be using non renewable energy
What idea of Darwin's based on fossil and the modern organisms he found basically says that genetic changes are inherited by later generations?
Heredity is the idea of Darwin's based on fossil and the modern organisms he found basically saying that genetic changes are inherited by later generations.
What describes the energy resources of the US?
America's energy resources can be described as nuclear, fossil, solar, renewables, wind, and water. Many of these energy sources are still relatively new but show promise as alternatives to fossil fuels.
Over geologic time changes to which feature of Earth have had the least effect on the course of evolution?
Fossil fuels
