The evolution of biological complexity is one important outcome of the process of evolution. Evolution has produced some remarkably complex organisms – although the actual level of complexity is very hard to define or measure accurately in biology, with properties such as gene content, the number of cell types or … See more Usually organisms that have a higher rate of reproduction than their competitors have an evolutionary advantage. Consequently, organisms can evolve to become simpler and thus multiply faster and produce more … See more If evolution possessed an active trend toward complexity (orthogenesis), as was widely believed in the 19th century, then we would expect to see an active trend of increase over time … See more The mutational hazard hypothesis is a non-adaptive theory for increased complexity in genomes. The basis of mutational hazard hypothesis is that each mutation for See more • Biocomplexity • Biodiversity • Biosphere • Complex adaptive system • Complex systems biology See more Recently work in evolution theory has proposed that by relaxing selection pressure, which typically acts to streamline genomes, the complexity of an organism increases by a … See more In the 19th century, some scientists such as Jean-Baptiste Lamarck (1744–1829) and Ray Lankester (1847–1929) believed that nature had an innate striving to become more complex with … See more WebSex is a label — male or female — that you’re assigned by a doctor at birth based on the genitals you’re born with and the chromosomes you have. It goes on your birth certificate. Gender is much more complex: It’s a social and legal status, and set of expectations from society, about behaviors, characteristics, and thoughts.
