Climatic factors has contributed to climatic change either direct or indirect. I recommend this website above to read, which talks about the factors (Solar radiation: a. Light, b. Heat and temperature, Moisture and wind). The writer go into details how they contributed to climatic change and you will see other references too.

Int J Dev Biol - Loss of plakophilin 2 disrupts heart development in zebrafish

Int J Dev Biol - Loss of plakophilin 2 disrupts heart development in zebrafish

This is interesting topic to read about the 'Loss of plakophilin 2 disrupts heart development in zebrafish.

The abstract talks about the desmosomal armadillo protein plakophilin 2 is the only plakophilin expressed in the heart, and mutation in the human plakophilin2 gene result in arrhythmogenic right ventricular cardiomyopathy.....

Developmental Biology! Animal Body Plans of Development.

The body of animal form as part of an inherited developmental sequence and the sequence starts after fertilization of an egg produced by the ovary form a Zygote. And this Zygote is single big cell until the process of cleavage started dividing itself into a large number of smaller cells named Blastomeres.

The cleavage starts in several different patterns: cnidarians and sponges lack a distinct cleavage shape, but bilateral animals, exhibit either radial or spiral cleavage. Based on the Biologist, assumed that these two types of cleavage each evolved and the animals with spiral cleavage form a monophyletic group, compared to the animals with radial cleavage.

Radial cleavage are typical of echinoderms, chordates and hemichordates. It occurs with regulative development where each blastomere of the early embryo.

Spiral cleavage are typical of mollusks, annelids and other protostomes. It occurs in form of mosaic development, which the organ-forming determinants in the egg cytoplasm etc.
