How did Lamarck pave the way for the work of later biologists?
Lamarck's theory of acquired characteristics proposed that traits acquired during an organism's lifetime could be passed on to offspring, an idea later proven incorrect but it stimulated interest in how traits are inherited. This idea set the stage for the development of the field of genetics and evolution, leading to the work of later biologists such as Charles Darwin and Gregor Mendel.
How is a coin toss model similar to the way in which traits are inherited in living things How are they different?
A coin toss model is similar to the way traits are inherited in living things because both involve the random passing down of characteristics. However, in living things, trait inheritance is governed by genetic material and can be influenced by various factors, while a coin toss is a simple probability model with equal chances for outcomes. Additionally, living things exhibit variation and evolution over time, which is not a characteristic of a coin toss model.
Explain the role of mutations in evolution?
Mutations are the material upon which natural selection acts. Evolution is a two sided coin. One side is mutation; the other side is natural selection. Without mutation there is no significant variation. Mutations are, however, ubiquitous. Every organism is a mutant. Evolution can be summarized as the non random survival of randomly varying replicators.
Does medicine have a reverse effect on evolution?
Evolution has no direction. I think you are asking about medicine ameliorating the effects of natural selection as portrayed in this terminology. " Survival of the fittest. " Biologists have never been too comfortable with that term because the ultimate coin evolution pays in is reproductive success, which is a somewhat different thing than just survival. Just because someone is kept alive by modern medicine does not guarantee this persons reproductive success. To launch tour genes into the gene pool is the " goal " of existence and not only do you have to survive long enough to do that your genes must be well represented in the future populations gene pool.

The sociologist who first described society as the survival of the fittest was?
The sociologist who first described society as the survival of the fittest was Herbert Spencer, not Charles Darwin. Spencer applied Darwin's principle of natural selection to human societies, coining the term "survival of the fittest" to explain social change and progress.
From an evolutionary stand point fitness is measured in?
Reproductive success is the coin evolution pays in.
Have we humans stunted our evolutionary path by increases in medical science?
No. This is a common misconception that natural selection will not eliminate the " weak " id we medically ameliorate their problems. This misconception is even held by some biologists. Actually, the coin evolution pays in is reproductive success and natural selection can be a creative force to that end. Evolution is the change in allele frequency over time in a population of organisms and the " stunted path " concept implies progress in evolution, but evolution does not care about progress, only reproductive success. If alleles change frequency in populations of organisms, which they do, evolution is not being " stunted, " whatever that means.
