EPISODE ONE

http://www.wired.com/2014/03/cosmos-image-gallery/

1. WHAT DID YOU LEARN OR FIND FASCINATING?

  • The structure of our cosmos: Earth – Solar System – Milky Way Galaxy – Virgo Supercluster – The Cosmos.
  • Our cosmos was created through a Big Bang.
  • The Sun doesn’t exist for the first few months of the Cosmic Calendar.
  • Comets shower abolished the existence of dinosaurs on Earth.
  • Humans have only started to evolve within the last seconds of the Cosmic Calendar.

2. WHAT ARE YOU INTERESTED IN LEARNING MORE OF?

  • The Earth’s early conditions (atmosphere, diversity, topography, and so on) when humans first evolved.
  • The effects of human evolution on other living things.
  • The process scientists went through to map out our cosmos.

3. EXTRA COMMENTS?

  • I love the concept of the Space Odyssey, and am definitely keen on the style of narration. The special effects and photos of outer space are out of this world (pun intended!). I am excited to continue watching!

EPISODE TWO

1. WHAT DID YOU LEARN OR FIND FASCINATING?

  • Factors affecting evolution includes inter-species relation, natural selection and artificial selection.
  • Artificial selection is when human interference contributes to the resulting mutation – which ultimately leads to evolution. Meanwhile, natural selection is when the mutation that leads to evolution is utterly caused by natural factors. Natural selection ensures that only the strongest, better-adapted species survive.
  • Mutation due to transcription and translation is entirely random.
  • The genetic code is universal, hence all living things shares a common ancestor.
  • Evolution reshapes species by little tweaks in the genetic code over generations, but it can’t start over and create entirely new species.
  • Evolution is “blind” to catastrophes, this leads to extinctions.

2. WHAT ARE YOU INTERESTED IN LEARNING MORE OF?

  • Same as episode one.
