Darwin’s theory of natural selection, shows individuals that survive are those that have

variations best suited to the environment.

Which concept is NOT included in the modern theory of evolution?

transmission of acquired characteristics

Darwin began to formulate his concept of evolution by natural selection after

observations of species and their geographical locations.

When Darwin returned from the voyage of the Beagle, he

wrote about his ideas but waited many years to publish them.

Darwin's voyages allowed him to

collect samples that lead to the conclusion of evolution

Darwin’s theory of evolution is based on the idea(s) of

natural variation and natural selection.

our wisdom teeth are vestigial structures that suggest

common ancestors that needed them

how is common decent supported by homologous structure

similar structures with different uses from ancient ancestor

Lamarck proposed that organisms

inherit all of the adaptations they display.

The tortoises that Darwin found displayed different structural adaptations, what is one

variation in length of the tortoises’ necks.

Lamarck’s theory of evolution includes the concept that new organs appear as a result of

Characteristics obtained throughout their lives

On the Galápagos Islands, Charles Darwin observed

similar species with traits that suited for the environment

If 3 is the anceint ancestor why might bird 4 evolved over time

chance mutation that allowed him to feed better
