Detailed explanation-1: -The embryos of two different organisms are observed to have similar features. What is the most reasonable conclusion that can be drawn from this observation? These organisms are related by a shared common ancestor.
Detailed explanation-2: -What is the most reasonable conclusion that can be drawn from a comparison of these structures? Humans and bats share a closer evolutionary history with each other than with birds. Comparing the embryos of different animals can show relationships that can’t be seen when comparing the fully formed animals.
Detailed explanation-3: -chimera, in genetics, an organism or tissue that contains at least two different sets of DNA, most often originating from the fusion of as many different zygotes (fertilized eggs).
Detailed explanation-4: -Similar anatomy across different species highlights their common origin and can be seen in homologous and vestigial structures. Embryology provides evidence for evolution since the embryonic forms of divergent groups are extremely similar.
Detailed explanation-5: -For a vast range of creatures, the primary stages of embryo development are nearly identical. Almost all types of life share the same genetic code, implying that species descended from a common ancestor who shared the same genetic code, which would explain why different organisms’ stages of development are so similar.
