Prior to Darwin, the general consensus among natural philosophers was that each species was created how many times ? And that once created, never occurred

A farmer breeds sheep with the desired traits of disease resistance and tine wool. After several decades of breeding efforts, the farmer's flock is resistant to disease and produces fine wool. Which evolutionary mechanism is responsible for the changes in the gene pool of the farmer's flock? A:Sexual selection B:Artificial selection C:Natural selection D:Gene flow

Alfred Russel Wallace agreed with Charles Darwin about which of the following evolutionary ideas? that the most common force causing evolutionary change is natural selection that the most common branching pattern in speciation is cladogenesis that the most common geographic pattern in speciation is sympatric that the most common branching pattern in speciation is anagenesis that the most common geographic pattern in speciation is allopatric

What evidence convinced Darwin that species change over time?

What did the Scottish geologist James Hutton claim about a possible evolutionary mechanism similar to natural selection (many years before Charles Darwin and Alfred Russel Wallace)? selection for heritable variation could improve neither varieties nor species of plants and animals artificial selection of crops and livestock improves plants and animals more than natural selection only natural selection, not artificial selection, could lead to improved plant and animal species only artificial selection, not natural selection, could lead to improved plants and animal species selection for heritable variation could improve varieties, but not species, of plants and animals

What causes variation among a population of living things and  How can variation in one generation influence the next generation? Is the  variation in a population will be examined as the “raw material” upon which natural selection acts.  Why are there so many different kinds of living things? Comparing species that exist today reveals a lot about their relationships to one another and provides evidence of common origins. This session explores the theory of evolution: change in species over time.

The most important piece of evidence missing from Darwin’s original hypothesis was:

Is natural selection only a negative process that removes nonadapted and lesser adapted forms? Explain your answer.

Explain Darwin’s theory of descent modification.

Identify the random and nonrandom components of Darwin’s theory of natural selection.
