My Inner Fish Reflection

My Inner Fish Reflection

This video series was about understanding our past ancestors and their traits that have pasted on to us. The first video was my inner fish and that was focusing on the similarities between fish and modern day humans and how even though they don't look alike they have similar bone structures. The second video, my inner reptile, was talking about those same things and also talking about the transition from fish in water to land living reptiles. Reptiles have a hard scale skin that derived from fishes' scales that were much less hard. This video series helped me understand evolution more and also the connection between animals and reptiles to modern day humans.
Why are mass extinctions important? Mass extinctions are important because they allow smaller species to evolve and live without being in danger from larger animals. Without mass extinctions the dinosaurs might have still been alive and dominating the Earth which wouldn't have allowed other species to evolve and survive. Without mass extinctions there is an extremely high possibility that us, modern day humans, wouldn't extinct today.
How and why did hair first evolve? Hair first evolved because of colder climates to keep species warmer. This is a prime example of how important and useful traits have been passed on to us. Without hair many animals today would not be able to survive.
