Practise IB Biology SL A4.1.5 by explaining how similar environmental pressures produce analogous structures through convergent evolution.
Convergent evolution increases similarities, despite differences in origins.
Explain how analogous structures can evolve.
a. evolution occurs by natural selection;
b. analogous structures come from convergent evolution;
c. analogous structures have similar functions or structures evolved from different ancestry;
d. similar conditions/environments have similar selective pressures favouring similar adaptations;
e. similar functions/functional requirements result in similar adaptations/structures;
f. e. g. torpedo shaped body in sharks and whales to facilitate swimming/ another verified example;
