Evolution

Living species are identical to their ancestral species.

Evolution is a process that occurred only in the past.

Living species are descendants of ancestral species that were different from present-day ones.

Evolution is a process that happens only to animals.

It proposed that all species are unchanging.

It suggested that all life is connected by common ancestry and changes over time.

It stated that Earth is young and species are recent.

It denied the existence of adaptations.

Natural selection creates new traits in a population.

Natural selection selects for traits already present in the population.

The environment determines which traits are selected for or against.

Natural selection always leads to extinction.

Because sedimentary rocks are formed from deposited sediments that bury and compress ancient life

Because sedimentary rocks are the hardest type of rock

Because sedimentary rocks are formed by volcanic activity

Because sedimentary rocks are always found underwater

Deeper rock layers contain older and simpler fossils

Upper rock layers contain younger and more complex organisms

Fossils are only found in volcanic rocks

The fossil record reveals evolution over time

lizards

birds

Artificial selection and natural selection both result in changes in species, but artificial selection is guided by humans.

Artificial selection occurs naturally in the wild, while natural selection only happens in controlled environments.

Natural selection produces changes in species much faster than artificial selection.

Artificial selection cannot result in significant changes in species.
