Hey guys, it's Eunice L.
Today, we reviewed Darwin and Lamarck. Finding similitaries and differences between both of their theories. We then moved onto Evidence Revolution.
HOMOLOGOUS STRUCTURES
Are similar organisms that adapt to different enivronments in which the functions of appendeages are changed.
ANALOGOUS STRUCTURES
Are different organisms that started to live in similar environments in which the functions of appendages evolved, performing the same function.
VESTIGIAL STRUCTURES
Are structures that continue to remain in organisms but have no fuction. Such as leg bones and the pelvis in snakes and whales.
COMPARATIVE EMBRYOLOGY
By obeserving embryos of organisms, embryos that are similar are found to be more closely related.
BIOCHEMICAL EVIDENCE (MOLECULAR BIOLOGY)
The relationship of amino acids and DNA sequences. Such as how a chimpanzee's and a human's hemoglobin are alike.
Don't forget the Endangered Species Project!
Here are some videos about Evolution

The last one I'm not sure if it has much to do with evolution, but I think it's pretty cool.
