Evolution Vs. Biological evolution
Gradual change or development of something over time and the evolution of the gene pool of a population
Micro-evolution Vs Macro-evolution
Change in the allele frequencies within a species or population and change that occurs at or above the eye level of a species over a long period of time
Lineage-splitting (speciation) vs. adaptive radiation
Where new species are formed by Cladogenesis forming a clade and the burst of divergence from a single linage to give rise to new species from a single ancestor
What is natural selection and its process?
A mechanism of evolution where the best adapted to the environment survives and reproduces. There are more offspring produced than are required, Natural variation among group is there,A change in the environment lead to differential reproduction or survival of the fittest,then Characterstics (traits) were heritable
10 Skeletal/Skull/Brain differences between African apes and humans prospectively
Big toes that are divergent-toes that are short and straight
Bow-shaped spinal spine-S (curved) shaped spine
Enlongated ilia(hipbone)-bowl-shaped pelvis
Fermurs is shorter and straighter-Femurs that slants towards midline keeping knees close together
Pronounced Brow ridge-large brain case
Sloping face-vertical face
Large caninies and diastema-Small canine
Large jaw bone-chin
Smaller brains/ capacity-Larger brain/capacity
Foramen magnum located near the back(rare) of the Under-surface of skull- Foramen magnum is in the middle of under-surface of skull
