Biology

Alina [70]3 years ago
5 0

First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.

After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.

After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.

After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".

At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.

what is the only characteristic currently known to be unique to all dinosaurs and why is it important
motikmotik
There are multiple characteristic that all dinosaurs shared. Some of the synapomorphies include:
- Vertebrates; skeletons with back bones that surrounds a nerve cord.
- Amniotes; specially adapted for life on dry land.
- Diapsids; two holes located above and behind the eye sockets on each side of the skull.
- Archosaurs; antrobital ferestra, a hole between the nasal hole and the eye socket hole.
But still all of this doesn't separate them from all others, what is unique to them is that all of the 'true dinosaurs' were land dwellers.
