Question

Select all that apply. How have fossils contributed to our understanding of evolution? Fossils can show the slow changes of macroevolution Some fossils are detailed and can show homologous structures Every living thing has left a fossil A collection of fossils from the same strata can give us a picture of the organisms that could survive during that time period.

Answer 1

All of the above points are valid for fossils' contributions in understanding the process of evolution. They allow us to study the ancestry, we can see the homologous organs or structures, if fossils are well-preserved; different fossils can lead us to follow the cycles of the changes that occurred during macroevolutions, and fossils can be used to study different populations which had different body structures for surviving in different environmental conditions. 

Answer 2

all of the above is correct, i just got this correct
