Scientists believe that over millions of years lungfish changed to become the first amphibians. what evidence do scientists use to support this idea?

a.)the shape of rock formations
b.)direct observation
c.)fossil evidence
d.)data collected by early humans

I'd have to say C. Hopefully this helps!

chordata is the answer

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
