Darwin and Natural Selection

What key observation during Charles Darwin's voyage significantly influenced his development of the Theory of Natural Selection?

Charles Darwin proposed his Theory of Natural Selection before his voyage on the HMS Beagle.

Besides the Galapagos Islands, what broader aspect of Darwin's journey contributed to the development of his theories?

Darwin proposed the Theory of Natural Selection approximately ______ years after Lamarck's Theory of Use and Disuse.

Match the figures with their contributions to the theory of evolution:

Which evolutionary mechanism primarily explains the diversification of finch beak structures on the Galapagos Islands, as observed by Darwin?

The extinction of the original finch species represents a scenario where that species was outcompeted or failed to adapt to changing environmental conditions.

Explain how the varying beak structures of finches on the Galapagos Islands provide evidence for Darwin's theory of natural selection.

The Maui parrotbill's adaptation of tearing back bark to search for beetles represents a specific ______ that enhances its survival in its ecological niche.

Match each finch species with its primary food source, demonstrating the relationship between beak structure and diet as evidence of adaptive radiation:

Which of the following scenarios best illustrates the principle of 'Overproduction' as described by Darwin?

According to Darwin's theory, all variations within a population are considered adaptations that enhance survival.

Explain why 'Variation' is a prerequisite for natural selection to occur, according to Darwin’s theory.

A genetically acquired trait that enhances an organism’s ability to survive and reproduce in its environment is known as an ______.

Which statement accurately reflects the relationship between adaptation and natural selection?

Which statement best explains why Lamarck's theory of inheritance of acquired characteristics is considered incorrect?

According to Lamarck's theory, a weightlifter's child would inherit increased muscle mass due to the parent's acquired physical changes.

Explain why, according to modern genetics, altering one's hair color from black to blonde would not result in offspring with naturally blonde hair.

The reason that many scientists rejected Lamarck's theory is their understanding that there must be changes in the _______ information of a species for traits to be inherited.

Which of the following examples best refutes Lamarck's theory of inheritance of acquired characteristics?

How did the availability of food resources influence the evolution of giraffes, according to Darwin's theory of natural selection?

According to Darwin's theory of evolution, all giraffes originally had the same neck length, and the environment caused them to evolve longer necks.

Contrast the primary mechanism of evolutionary change proposed by Darwin with that of Lamarck, focusing on the role of environmental influence.

According to Darwin's theory, __________ favored the survival of giraffes with longer necks due to the lack of accessible food supply.

Match the following scientists with their contributions to evolutionary theory:

How did Lamarck contribute to the field of biology and evolutionary thought?

Lamarck's published work, Zoological Philosophy, was published after Charles Darwin's work on evolution.

In what publication did Jean-Baptiste de Lamarck present his ideas on evolution?

Jean-Baptiste de Lamarck was a French ______.

Match the scientist with their contribution to evolutionary thought.

Which of the following statements best encapsulates Lamarck's theory of evolution regarding acquired characteristics?

According to Lamarck's theory, if a giraffe stretches its neck to reach higher branches, its offspring will be born with longer necks.

Briefly describe how Lamarck's theory explains the evolution of a particular trait, such as the giraffe's long neck.

Lamarck believed that animals could alter their ______ characteristics to better utilize available resources.

Match the following concepts with their descriptions according to Lamarck's theory:

According to Lamarck's theory, which of the following scenarios would be most likely to drive evolutionary change in a population of birds?

Lamarck's theory suggests that if a weightlifter develops larger muscles during their lifetime, their offspring will be born with a genetic predisposition for increased muscle mass.

Lamarck's theory of ________ suggests that organs that are not used will disappear over time.

Which of the following statements best describes the central dogma of molecular biology?

Explain how Lamarck's 'Theory of Use and Disuse' would account for the evolution of flightless birds from flying ancestors.

Match each evolutionary concept with its description according to Lamarck's theory:

The primary function of transfer RNA (tRNA) is to directly catalyze the formation of peptide bonds between amino acids during protein synthesis.

Describe the role of RNA polymerase in the process of gene expression, detailing its function and the specific nucleotide sequences it recognizes to initiate transcription.

During DNA replication, the enzyme ______ is responsible for unwinding the DNA double helix, while ______ relieves the torsional stress created by this unwinding.

Match the following events with their specific phase in protein synthesis:

Which of the following best describes the core tenet of creationism regarding the origin and development of life forms?

Creationism suggests that species can undergo significant transformations over time in response to environmental pressures.

In the context of creationism, what is the key characteristic of life forms since their creation?

The idea that life forms were created in their present form and remain unchanged is known as ______.

Match the individuals and the descriptions based on their beliefs:
