because in their larval stage they are bilaterally symmetrical.
Yes, humans evolved from ancestors who had tails.
Derived characteristics, also known as apomorphies, are traits that have evolved in a particular group of organisms and are not present in their ancestors. Ancestral characteristics, or plesiomorphies, are traits that are shared with the ancestors of a group of organisms. The key difference is that derived characteristics are unique to a specific group and have evolved over time, while ancestral characteristics are traits that have been inherited from common ancestors.
The theory of evolution is supported by evidence such as the similarities in DNA and physical traits among different species that share common ancestors. This suggests that animals have evolved over time to adapt to different environments in order to survive and thrive.
That's correct! The theory of evolution states that organisms have evolved over time from common ancestors through the process of natural selection. This gradual change in species over generations is driven by factors such as genetic variation and environmental pressures.
Physiological similarities suggest the species evolved from the same ancestor.
Cnidarians are true radially symmetrical animals. They include jellyfish. Echinoderms (like starfish) also display radial symmetry. It is important to note that the larvae of echinoderms are bilaterally symmetrical and that Echinoderms evolved from a bilaterally symmetrical group.
I believe Echinoderms evolved first.
Because cats evolved from the ancestors of the fox - just as dogs evolved from the ancestors of the wolf.
Yes, humans evolved from ancestors who had tails.
A taxanomic tree.

vestigal
No, humans and dogs have evolved from different ancestors, they are completely different species.
Birds evolved from small reptiles that lived during the age of dinosaurs, but not from the dinosaurs themselves.
clown fish have bilateral symmetry
Some anthropologists believe that dancing evolved as a way to signal that dancers were symmetrical, and therefore were more fit as mates.
