Quick Quiz
It looks like your students have some questions about Patterns seen in evolutionary relationships. Reflect on what you have just learned and see how well you can respond. Just click on their raised hands!
You could respond:
“As science gained more knowledge about how things are related
the kingdoms were replaced by Archaea, Bacteria, and Eukaryota, often referred to as the ‘Three Domains’ of life.”
You could respond:
“Homologies are features possessed by different organisms that are
inherited from a common ancestor. They give us clues about how closely two or more living things are related to each other.”
You could respond:
“He had no sense of evolution and didn’t recognize the actual
relationships between living things. This meant that he based his classification on which living things looked alike and that
doesn't always show us the correct relationship.”
You could respond:
“We have to go back six million years to find the grandma and grandpa
of both chimpanzees and humans. So, chimpanzees are our cousins a lot of times removed, but they are our cousins.”
You could respond:
“Yes.”
You could respond:
“A clade is a grouping that includes a common ancestor and all the descendents (living and extinct) of that ancestor. Basically, it’s a bunch of related critters.”
You could respond:
“The wings are front legs that don’t look much like legs because they are adapted for flying.”
You could respond:
“Analogous characters may appear similar, but have separate evolutionary origins. Homologous characters are corresponding parts of different organisms that are similar because they were inherited from a common ancestor that also had that character.”
