Question

question 4
what evidence can developmental biologist and embryologist examine in regards to evolution?
it examines the maternal instincts of species to see how they care for their young.
it compares embryo development to show that all species are different from the beginning and therefore are not related at all.
the process of reproduction in various species.
it compares early embryo development to see the similarities that show an evolutionary link between species.

Explanation:

Developmental biologists and embryologists study embryo development. By comparing early embryo development, they can identify similarities that suggest evolutionary links. Maternal instincts (first option) are more about behavior. The second option is incorrect as embryos of related species show similarities. Reproduction process (third option) is too broad. The fourth option aligns with their focus on embryo - based evolutionary evidence.

Answer:

It compares early embryo development to see the similarities that show an evolutionary link between species.
