“Which Came First – The Chicken or the Egg?”

25 Jan

Proving whether the chicken or the egg came first! This relates to the Genetics topic. It talks about DNA, replication, and mostly about mutations.

Random bio related things I learned from the video:

1.) The protein needed for chicken eggs (for the shell) is OV-17.

2.) Some idea of evolutionary pressure. More specifically selective pressure in the evolution of dogs from wolves.

3.) No one mutation can make an entirely new species.

Things we learned in class that were mentioned in the video:

1.) Genetic information is passed in the form of DNA in reproduction.

2.) Mutations occur when there is an error in the replication of the DNA.

3.) Mutations occur in the zygote.

I thought this was a super cool and interesting video 😀
