What is Cytochrome C and its significance in evolution?

Back

Cytochrome C is a protein found in the mitochondria of cells, crucial for energy production. Its similarity between humans and chimpanzees indicates a close evolutionary relationship.

What is a vestigial structure?

Back

A vestigial structure is a body part that has lost its original function through evolution. An example is the human tailbone (coccyx), which is a remnant of a tail.

Front

What is the Coccyx?

Back

The Coccyx, commonly known as the tailbone, is a small, triangular bone at the base of the vertebral column in humans, representing a vestigial structure.

Front

What does the fossil record indicate about the age of fossils?

Back

The fossil record shows that fossils buried in layers near the surface are generally younger than those found in deeper layers, providing evidence for the timeline of evolution.

Front

What role did meat consumption play in human evolution?

Back

The consumption of meat is theorized to have contributed to the development of larger brains in humans, providing essential nutrients for brain growth.

Front

Define evolution in biological terms.

Back

Evolution is the process through which species change over time through variations and natural selection, leading to the development of new species.

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring, influencing the evolution of species.

Front

What are homologous structures?

Back

Homologous structures are body parts in different species that share a common ancestry, indicating evolutionary relationships, such as the forelimbs of humans and whales.

Front

What are analogous structures?

Back

Analogous structures are body parts in different species that serve similar functions but do not share a common ancestry, such as the wings of birds and insects.

Front

What is the significance of DNA in evolution?

Back

DNA contains genetic information that is passed from one generation to the next. Similarities in DNA sequences among species provide evidence for common ancestry and evolutionary relationships.
