This video is helpful for getting some idea of the concepts, but unfortunately it also contains some misleading or at least confusing statements, so make sure you consult other sources in order to get the right information.
Thank you for this clear explanation! I only have 1 question: homolasy is a character state found in at least 2 organisms and not in the ancestor, but this definition can also be correct for an apomorphy. Is it correct to say that an apomorphy is also a homoplasy?
is homoplasy the same or very similar to analogous features? Like functionally, for instance, bird and bat wings are the same, but they evolved separately in time and are structurally different. I would call that analogous, but if I understand properly homoplasy would also be an appropriate term?
It is all a matter of perspective. If you consider the taxon vertebrata, the vertebrae are an apomorphy of their common ancestor and a synapomorphy of all vertebrates. If you compare e.g. only birds, mammals and reptiles, the vertebrae are a symplesiomorphy, wheras the amniotic egg is a synapomorphy.

Thank you for making this video, I was really anxious approaching this topic. But the way you explained it cleared literally everything up.
You even gave an example at the end. Dude, I'm definitely subscribing!!!!!!
Have a midterm next week and this helped so much thank you🙏
Ma'am this is so useful. I cannot finish my assignment for Anthropology without this explanation. Thank you so much!

oh its very clear.. it helps me a lot. Thank you!
Glad it helped!😊
very simple and easily you make me understand this. thanks
Thank you this was very helpful 🙏🏻
Glad it was helpful!
Best video on the planet.

I think the difference is that homoplasy is for unrelated taxa while apomorphy is unique to a group or species (like a clade)
is homoplasy the same or very similar to analogous features? Like functionally, for instance, bird and bat wings are the same, but they evolved separately in time and are structurally different. I would call that analogous, but if I understand properly homoplasy would also be an appropriate term?
homoplasy ARE analogous
According to wikipedia Homology_(biology)#Homology_vs._analogy, analogy is called homoplasy in cladistics.
Is aminiotic egg is the synamorphy for birds, lemurs and humans. Since it is common to all these 3, and also its a derived one
Thank you for explaining clearly these confusing words!
Thank you so much!
thank you so much
Well explained 🤘
Thanks 🙂
Thank you maam
Why is synapomophy not an ancestral train when the ancestor also has it?
In synapomorphy even though the ancestor has the trait it is only exclusive to a single clade
@@IntrovertGeek Did the ancestor pass it on though or all species in the clade developed it independently?

thank for this maam!!
Welcome!
again thanks a lot
Always welcome
