Which observation best supports evidence that two different species share a common ancestor? a) they both prey on the same animals for food b) they both burrow into the ground for shelter c) they both have similarities in early embryonic development d) they both share similar biochemical pathways for energy production

The correct answer is option is C, they both have similarities in early embryonic development

Explanation:

The branch of biology which provide an early evidence of evolution in early embryos is called embryology. It is very commonly found that several characteristics are common in embryos of unrelated animals and human. For example both fish and human embryo have gills at embryo stage, while the gills of fish grow into a full fludged structure later on,  the gills of human embryo on the other hand disappear after certain period of time.

International Firefighters' Day is observed on May 4. It was instituted after a proposal was emailed out across the world on January 4, 1999 due to the deaths of five firefighters in tragic circumstances in a bushfire in Australia.
