1 point 7. Read the following claim. "Butterflies and moths have passed on useful
survival traits to their offspring through the process of natural selection."
What evidence from the article supports this claim?"
For now, Saccheri hopes that his study will help people appreciate the power of
natural selection. "This isn't a made-up story" he said. "There's more and more layers
of evidence."
Natural selection is an idea about the way living things have developed over millions
of years. It says that creatures with useful traits are more likely to survive and
reproduce. When they reproduce, they pass their useful traits on to their offspring.
This idea is also known as "survival of the fittest."
A family of brightly colored butterflies lives in the American tropics. Over hundreds of
years, they have been evolving at incredible speeds. Though they come in a wide
range of species, the butterflies share a taste for poisonous plants.
"It's amazing because [Heliconius and peppered moths) haven't had a shared ancestor
in over 100 million years,' Saccheri said. The two are very different organisms.
However, they share the same cortex gene.
