Solution
Fossil record & Genetic evidence:
It has clearly observed the predicted order of trait appearance has been increasing as the actual
order of appearance of trait increases among a group of species. Therefore, according to “a
descent with modification of a trait i.e. derived from a common ancestor (a fossil species arose
from a common ancestor)” specifically changing over time. This change was observed in
phylogenetic tree of multicellular organisms (from porifera with no symmetry to bilateral
symmetric species) as “a linear hypothetical relationship between the predicted order of trait
appearance based on trait nesting and the actual order of appearance in the fossil record for a
number of traits among a group of species”.
Fossil species are different and they are transitional fossils as they often resemble and exhibit
both the groups of organisms. They often different in the DNA sequences when perform DNA
sequencing even though they look similar morphologically thereby paleontologists often classify
them as per their interspecific and intraspecific genetic variations (pan genes, core genes)
variations. Fossils are formed due to catastrophism and gradualism, their classification is based
on their body size, and body weight for example dinosaurs is the common ancestors of both birds
and reptiles. Thereby different paleontologists show different family trees for the same fossils.
Blast search engine
The above multicellular eukaryotic classification as per PSI-BLAST considerably along with
matrix -based alignments is used to reveal the amino acid substitution in every species for gene
expression similarity so that protein synthesis can be compared with every species in relation to
higher eukaryotes (chordates). PPSM (position specific scoring matrix) is widely used to get
either positive or negative results in relation to the substitution of the amino acids for protein
multiple sequences.
Delta Blast is more useful in detecting and is identifying “species proteins from lower
multicellular porifera species to annelids, arthropods, non-chordates & chordates” in which

PSI- BLAST. Some time PSI-Blast also enables to get possible information in identifying the
evolutionary nucleotide substituent’s in the species, which are not closely related.
Nervous system:
The three animal phyla that best represent stages in the evolution of the nervous system of
animals are animals belongs to primitive bilateria, Cnidaria and Ctenophora since these are often
referred as Epitheliozoa. These animals often diversified from primitive sponges where primitive
neuronal system has developed already. The nervous system present in these phyla have no
complex brain structures but have neural canals and long single neuronal cells to transmit
synaptic responses to muscle cells. The long neuronal cells are completely single celled so that a
better model to examine motor effects for cutting -edge research for example in Caenobacter
elegans. Prior to these animal phyla, species belongs to arthropods, annelids often belongs to
protostomes possess simple neuronal system with no brain structure later evolution of highly
developed vertebrates with complex CNS, brain often deuterostomes phylogenetically evoluted.
The neuro-active molecules can describe the efficient neuronal activity for example, caeffine is
going to act on the ATP receptors & produces excitatory responses whereas epinephrine is going
to act on adrenergic receptors finally exert G-protein coupled receptors-mediated excitatory
signaling mechanism. The GABA is a inhibitory neurotransmitters so that it is going to produce
inhibitory responses on the neurons. These molecules are going to produce differential effects on
single-neuronal cells to synaptic plasticity finally active on multi-cellular activity
