¡Evolution!
From The Stars
To You
All life
on planet
Earth
including us
humans
is made
out of
star dust
called Atoms
Atoms tend to stick together to form the material that makes us
and everything else around us.
Originally, this universe started with what is called the Big Bang,
increasing energetically in size from a singular point outwards in all
directions. Hydrogen atoms were mostly created when this happened
Hydrogen is the simplest of the Atoms and the lightest of them all .
Stars are made out of hydrogen and the first stars were formed from the
hydrogen produced in the Big Bang which accumulated into large
concentrated densities. From the gas left over that originally formed in
the Big Bang new stars continue to form all the time
Our own Sun is a type of star.
¡Look at our Sun shine!
A solar flare is a sudden flash of increased Sun’s brightness, usually
observed near its surface. These can be powerful enough to cause
huge areas of electronic failure on planet Earth.
Our own Sun is a type of star.
Different types of atoms than the original atoms of hydrogen the star was
mainly composed of are created, transformed from the hydrogen during
the star’s life or in different types of stellar events. Our Sun is currently
burning, or fusing, hydrogen to helium. This is called Nucleosynthesis
Nucleosynthesis periodic table
This other type of star, larger than our own Sun is of a type that explodes
at the end ot its life and is called a Supernova. Elements heavier than iron
are made in this type of stellar event
Nucleosynthesis periodic table
These are Neutron Stars attracted to each other until they crash
Scientists think that Gold and silver are made in this type of event
Nucleosynthesis periodic table
IAfter different types of stellar explosions the atomic matter is expelled
into outer space and clumps around newly forming stars so older stars
add to new stars
This is a young star & its
protoplanetary disks, forming
from remains of older ones
which have reached the end
of their lives once they
have exploded, combining
with the relatively abundant
gas hydrogen, left over
from the beginning of the
universe
The matter from generations of different stars clumps together into very
large objects which form planets around stars like planet Earth
Once the matter made
out of all the types of
atoms mix and react
(mix at a molecular
level) with the water
on a planet like Earth
the possibility for life
to happen occurs
This is an
imagined
recreation of
what an
asteroid or
comet impact
with planet
Earth would
look like
from outer
space.
This is an

from the
surface of
planet Earth
On the Early Planet Earth billions of
years ago all life was very small and
simple
We still have very
similar lifeforms
alive today. By
studying them using
technology .like this
microscope we can
figure out that some
of the original
lifeforms were our
ancestors
All plants and animals that exist today are genetically related in the tree
¿Do you know what these are?
They are fossil ammonites. Fossils are any preserved remains,
impression, or trace of any once-living thing. These remains are found
preserved through mineral replacement in sedimentary rock after
hundreds of thousands to millions of years
Scientists believe that ammonites were marine free swimming animals
and that they looked as an octopus but carried a shell just as snails do
They looked similar to an octopus like this one
But they carried a shell like this snail. This is not a coincidence
in this case. Octopus and snails are closely related. Both
belong to a general type of animal call molluscs
Molluscs are a numerous and diverse in form group of animals
but we know that they all had the same common ancestor.
This type of extinct mollusc is called Orthoceras, a type of
Nautiloid
These are fossil Orthoceras that are still embedded in their
matrix, the original rock they were found in. They have an
age of approximately 490 million years
These are Orthoceras fossils that have been individually been
extracted from the rocks they were found in. This takes a lot
of work which makes them cost more
This a Nautilus, another type of Nautiloid but this species can
still be found alive swimming in the oceans to this day
Not all fossils are related to the molluscs which are the ones most
commonly found. There are many types of fossilised animals and plants
¿What is this type of fossilised carnivore called?
Once we find the fossil remains of a life form we can reconstruct with
quite a degree of accuracy what it looked like
This is a tyrannosaurus Rex
¿What is this type of fossilised herbivore called?
This is a stegosaurus. It had a spiked tail probably used as a weapon
This is a stegosaurus. It had a spiked tail probably
used as a weapon
¿What is this fossilised flying creature called?
This is called archaeopteryx
¿Do you know what this is a fossil of?
These fossils are the remains of animals that have lived in more recent
times that the ammonites or Orthoceras, from a few million yearsago to a
few thousand
This is a Woolly Mammoth
Mammoths lived from around 5 million years ago to about 4,500 years
¿Do you what this is a fossil of?
These fossils are related to what we now think eventually branched of
and evolved into the Human species. This is a type of
Australopithecus.
From the fossil bones we can
work out how the flesh that
covered them looked like
and artisticallyrecreate them.
This creature, although it
looked like a chimpanzee,
walked just like a Human
on 2 legs
It walked
something like
this
Chimps walk on all fours most of the time. This is called knuckle
walking
Do you know from what type of human this fossil skull is from? It is
even more recent that the australopithecus!
!
This skull was found in Gibraltar in 1848
It is from a neanderthal woman. Neanderthals were until very
recently thought to have gone extinct
Neanderthals were much stronger than us. They looked different to us.
They had big lips and noses. They also had no pointed chins
Nearderthals did not die out completely. They were like our cousins.
There is a little bit of neanderthals still alive in most people
Here we have
speeded up an
evolutionary
version, from
when our
ancestors had a
common
ancestor with
the
chimpanzees,
to the present
Today we have studied the tree of life on our planet Earth which has
inclusively been formed from other parts of the Universe. Seeing as this
Universe is so big and there is so much of the material for life to live of
across the Universe, can other trees of life exist elsewhere?
Scientist think that it is very possible that life forms have arisen
independently in other parts of the Universe
These forms of life could have taken different evolutionary pathways
than that on planet Earth
Considering that we humans are life forms and that we are
made of the material itself made in the Universe, we think that
intelligent life in the Universe is the Universe aware of itself
Hasta Luego ¡Hasta Luego!¡Have a nice day!

  • 17. This is an imagined recreation of what an asteroid or comet impact with planet Earth would look like from outer space.
  • 18. This is an imagined recreation of what an asteroid or comet impact with planet Earth would look like from the surface of planet Earth
  • 19. On the Early Planet Earth billions of years ago all life was very small and simple
  • 20. We still have very similar lifeforms alive today. By studying them using technology .like this microscope we can figure out that some of the original lifeforms were our ancestors
  • 21. All plants and animals that exist today are genetically related in the tree
  • 22. ¿Do you know what these are?
  • 23. They are fossil ammonites. Fossils are any preserved remains, impression, or trace of any once-living thing. These remains are found preserved through mineral replacement in sedimentary rock after hundreds of thousands to millions of years Scientists believe that ammonites were marine free swimming animals and that they looked as an octopus but carried a shell just as snails do
  • 24. They looked similar to an octopus like this one
  • 25. But they carried a shell like this snail. This is not a coincidence in this case. Octopus and snails are closely related. Both belong to a general type of animal call molluscs
  • 26. Molluscs are a numerous and diverse in form group of animals but we know that they all had the same common ancestor. This type of extinct mollusc is called Orthoceras, a type of Nautiloid
  • 27. These are fossil Orthoceras that are still embedded in their matrix, the original rock they were found in. They have an age of approximately 490 million years
  • 28. These are Orthoceras fossils that have been individually been extracted from the rocks they were found in. This takes a lot of work which makes them cost more
  • 29. This a Nautilus, another type of Nautiloid but this species can still be found alive swimming in the oceans to this day
  • 30.
  • 31. Not all fossils are related to the molluscs which are the ones most commonly found. There are many types of fossilised animals and plants ¿What is this type of fossilised carnivore called?
  • 32. Once we find the fossil remains of a life form we can reconstruct with quite a degree of accuracy what it looked like This is a tyrannosaurus Rex
  • 33.
  • 34. ¿What is this type of fossilised herbivore called?
  • 35. This is a stegosaurus. It had a spiked tail probably used as a weapon
  • 36. This is a stegosaurus. It had a spiked tail probably used as a weapon
  • 37. ¿What is this fossilised flying creature called?
  • 38. This is called archaeopteryx
  • 39.
  • 40.
  • 41. ¿Do you know what this is a fossil of? These fossils are the remains of animals that have lived in more recent times that the ammonites or Orthoceras, from a few million yearsago to a few thousand
  • 42. This is a Woolly Mammoth Mammoths lived from around 5 million years ago to about 4,500 years
  • 43. ¿Do you what this is a fossil of?
  • 44. These fossils are related to what we now think eventually branched of and evolved into the Human species. This is a type of Australopithecus.
  • 45. From the fossil bones we can work out how the flesh that covered them looked like and artisticallyrecreate them. This creature, although it looked like a chimpanzee, walked just like a Human on 2 legs
  • 47. Chimps walk on all fours most of the time. This is called knuckle walking
  • 48. Do you know from what type of human this fossil skull is from? It is even more recent that the australopithecus! ! This skull was found in Gibraltar in 1848
  • 49. It is from a neanderthal woman. Neanderthals were until very recently thought to have gone extinct
  • 50. Neanderthals were much stronger than us. They looked different to us. They had big lips and noses. They also had no pointed chins
  • 51. Nearderthals did not die out completely. They were like our cousins. There is a little bit of neanderthals still alive in most people
  • 52. Here we have speeded up an evolutionary version, from when our ancestors had a common ancestor with the chimpanzees, to the present
  • 53. Today we have studied the tree of life on our planet Earth which has inclusively been formed from other parts of the Universe. Seeing as this Universe is so big and there is so much of the material for life to live of across the Universe, can other trees of life exist elsewhere?
  • 54. Scientist think that it is very possible that life forms have arisen independently in other parts of the Universe
  • 55. These forms of life could have taken different evolutionary pathways than that on planet Earth
  • 56. Considering that we humans are life forms and that we are made of the material itself made in the Universe, we think that intelligent life in the Universe is the Universe aware of itself
  • 57. Hasta Luego ¡Hasta Luego!¡Have a nice day!
