What was lamarcks hypothesis about how species change?
Lamarck's hypothesis about evolution was that animals would change based on their environment during their lifetime and pass on those traits to their offspring. This is different from Darwin's theory in that all animals mutate in someway and it's the surviving mutations that pass on that slowly change the animal over many generations.
What were the lamarcks two theories of how organisms evolved?
Concepts more than theories. Use and disuse. A anatomical part of an organism would fade away if not constantly used and would enhance itself is used. The giraffe neck as an example of use. Acquired characteristics. Characteristics that one developed over the course of a lifetime could be passed on to progeny. Such as the developed muscles of a blacksmith could be inherited by his children. Naturally, both these concepts were absolutely refuted by the theory of evolution by natural selection.
How have dogs changed over time?

What Charles Darwin theory did Herbet Spencer argue applies to humans too?
The theory of evolution by natural selection, of course. Herbert Spencer was wrong about many things but he was not wrong about this. Humans are the ultimate, though partial product, body and mind, of naturally selective process over many years in many differing environments.
What did Darwin conclude about the animals on the Galapagos islands?
They had changed over time
How has the expanding earth theory changed over time?
By now, this should not still be a theory, it should be common knowledge.
How have animal populations changed over time?
Charles Darwin Theory of natural selection
Name a scientific theory that has changed?
The theory of continental drift has changed over time. Initially proposed by Alfred Wegener in the early 20th century, it was met with skepticism. However, over the years with advancements in technology and research, the theory evolved into plate tectonics, which is widely accepted today.
Evolution say the world was created how?
Evolution does not propose that the world was created. Instead, it explains how life forms have changed and adapted over billions of years through natural selection and genetic variation. The theory of evolution is focused on the development of life on Earth, not the creation of the Earth itself.
How did Darwinism change history?
Charles Darwin changed history with his theory of evolution. His theory of evolution suggested that species undergo small changes over time.
How do scientists know that living things have changed over time?
Scientists use various lines of evidence, such as the fossil record, comparative anatomy, embryology, and genetics, to show that living things have changed over time. By studying these pieces of evidence, scientists can construct evolutionary relationships and track changes in species over generations. This accumulation of evidence supports the theory of evolution.
Who is theory changed Linnaeus's method of classification?
Charles Darwin's theory of evolution changed Linnaeus's method of classification. Darwin's theory emphasized the idea of common descent and the branching of species over time, which led to the development of the modern classification system based on evolutionary relationships.
Which statement is not included as a part of the modern theory of evolution?
The statement that all organisms were created in their current form and have not changed over time is not part of the modern theory of evolution. Evolutionary theory explains that organisms have changed and diversified over time through processes like natural selection and genetic variation.
What later evidence disproved Lamarcks theory of acquired characteristics and supported Darwins theory?
Later evidence from genetics and molecular biology showed that acquired traits are not passed down through generations as proposed by Lamarck, as they do not alter the genetic material. On the other hand, Darwin's theory of natural selection was supported by the discovery of the mechanism of inheritance through genes and DNA, providing a more robust explanation for evolutionary change over time.
Can a theory change over time?
yes, as more things are learned theories can be modified (theory of evolution) also sometimes theories can be thrown out (the theory that the earth is flat)
How does the development of the theory of plate tectonics demonstrate scientific process?
it shows how the earth used to be and how it spread and changed over time
What theory states that Earth's landmasses have changed position over time?
The theory that states Earth's landmasses have changed position over time is called plate tectonics. It suggests that Earth's outer shell is divided into several plates that move and interact with each other, leading to the shifting of continents. This movement is believed to be driven by processes within the Earth's mantle.
