Darwin's theory of evolution is based on natural selection, where organisms with advantageous traits are more likely to survive and reproduce, passing those traits to future generations. In contrast, Lamarck's theory, known as Lamarckism, posits that organisms can acquire traits during their lifetime based on their needs or environmental pressures and then pass those acquired traits to their offspring. While Darwin emphasizes genetic variation and survival of the fittest, Lamarck focuses on the direct adaptation of individuals to their environments over generations. Ultimately, Darwin's ideas are supported by modern genetics, while Lamarck's have been largely discredited.

Whose population theories did Wallace and Darwin believe in?
Wallace and Darwin believed in Thomas Malthus's population theories, which proposed that population growth would eventually exceed resources, leading to competition for survival. This concept of natural selection as a result of competition for limited resources played a key role in shaping both Wallace's and Darwin's ideas on evolution.
Why were Darwin's publications of the origin of species controversy?

How did the study of Galapagos finches help Darwin to form some of his theories and how do we know that some of these theories are true?
The subtle differences between the beaks of Galapagos finches, and their distribution over the different islands helped Darwin to formulate his theory of Natural Selection. We know that this is true because it is constantly observable in the world around us.
What islands did Darwin study?
Charles Darwin visited Floreana, Isabela, San Cristóbal, and Santiago islands.
What did Darwin think about his journey home from England?
Darwin viewed his journey home from the Beagle expedition as a formative experience that profoundly influenced his scientific thinking. He reflected on the vast array of observations he made during the voyage, which contributed to his developing theories on evolution and natural selection. The return trip allowed him to contemplate the evidence he had gathered and solidified his commitment to studying and explaining the diversity of life on Earth. Ultimately, this journey was pivotal in shaping his intellectual path and the formulation of his groundbreaking ideas.
Whose theory stuck between Lamarck and Darwin?
lamarcks theory of natural selection was accepted as they believed in religion and didnt want to believe anything other than god created our planet. darwin believed in evolution and plants and animals develop without the aid of intelegent creater through natural selection. lamarcks believed animals changed to fit there habitat for eample a girrafe reached for tall tree's and eventually grew into tall necks. At this period of time niether lamarck are darwin new about genes and in that so came up with these theories. hope this helps xoxox
When it came to Darwin explaining the origins of variations within species?
Various evolutionary theories had already started to form when it came time for Darwin to publish On the Origin of Species. The book attracted interest on a national level and made arguments for "survival of the fittest."
What is the difference between evolution and theories of evolution?
Evolution is the process by which species change over time through natural selection. Theories of evolution, such as Darwin's theory of evolution by natural selection, are explanations for how evolution occurs and the mechanisms driving it. In essence, evolution is the phenomenon, while theories of evolution are the explanations for how it happens.

What are differences between Spencer's and Darwin's theories?
Spencer's theory of social evolution focused on the idea of survival of the fittest and that individuals and societies evolve through competition. Darwin's theory of natural selection, on the other hand, specifically applied to biological evolution, explaining how species evolve and adapt to their environment through genetic variations. While both theories share some similarities, Spencer's theory is more generalized and applied to social and cultural aspects, while Darwin's theory is based on biological principles.
