Is made of cells
Cells use DNA to copy themselves.
Has mitochondria in cells
Cells have cell nucleus
Reproduces through sexual reproduction
Multicellular and cells are held together with collagen
Cells organized into three layers: endoderm, mesoderm, and ectoderm
Cells organized into true tissue. Nerves, muscles.
Three layer organization allows for tissue to organize into true organs
When just an embryo forms a blastula (hollow ball of cells—microscopic beachball)
Bilateral symmetry (you could draw a line down the middle). Has a head and tail.
Blastula develops into a tube shaped "tornarias" larva, tail end forming FIRST.
Has a spinal chord protected by vertebrae
Skull provides a hard braincase to protect the brain
Jaws
bony skeleton
Paired appendages
pectoral (shoulder) and pelvic (hip) girdles
Simplified pattern of bony plates in skull
Four limbs
Five fingers and toes
Ankle bones form: "Astragalus" and "Calcaneum"
Amniotic Egg protects embryo: Eggs can be laid out of water (and is laid internally)
One temporal opening in skull behind the eye socket (synapsid opening opening)
Three middle ear bones
Mammary glands nourish young with milk
Placenta connects embryo's and mother's blood and lymph systems and allows young to be born more
fully developed.
Stirrup shaped stapes (one of the middle ear bones)
Flexible ankles
Proportionately larger brain (compared to body size) than other mammals
Forward facing eyes
Fingernails
No tail
Small teeth
Obligatory bipedalism (must walk upright)
Smaller ribcage & thinner cheekbones (compared to Homo neanderthalensis)
